Quickstart - Soldering Basics and Advice
There are some basic tips that will help you achieve the best solder connection possible, help keep your soldering
iron in good condition and also keep you safe. For starters, it is best to keep your iron unplugged when not using it.
Leaving soldering irons on for long periods of time will wear out the tip much quicker. They are also very easy to
forget about when left plugged in and can be a potential fire hazard.
With that said, put on your safety glasses and plug your iron in to let it warm up before using it. Allow it to warm up
for about 30 seconds - 1 minute. The tip of the iron is normally 700°F, hot enough to melt metal solder. It is normal
for the handle of the soldering iron to heat up a bit. Hold it like a pencil and move your hand further away from the
tip if the heat is uncomfortable.
There isn't any indicator to let you know when the iron is ready. NEVER TOUCH THE TIP OF THE IRON TO SEE
IF IT'S ON. The best way to test if your iron is warmed up and ready is to melt a little solder on the end. If it melts
easily, you're good to go. The solder smokes because the rosin inside the solder is burning off - it’s not harmful. If
you have trouble getting the solder to melt on the tip, let it warm up a little bit longer.
Here's a close up of the solder once the solder is able to melt on the soldering iron tip.
The next bit of advice is always keep your iron in its stand while your not using it. Setting down your iron on your
workspace can be a major hazard. Not only can you burn the other items on your workbench, but you can also set
your arm down on it and get a gnarly burn (I speak from experience). Your iron has a home, and we're all better off
when you keep it there.
Maintaining Your Soldering Iron
You'll notice that on your stand there is a little pool with a sponge in it. This sponge plays a very important role in
soldering. As you solder, old solder tends to clump up and loose it's ability to melt and flow properly. It can also
build up a nasty residue on your iron tip and corrode it to the point were it won't accept solder any more. That's
where the sponge comes in handy.
Dampen it in a sink or using a water bottle. It doesn't need to be soaked, just wet enough to pull solder off you iron.
Now, very gently, wipe the excess solder off onto the sponge. Avoid jamming the tip into the sponge or leaving the
tip on the sponge for more than a few seconds. Doing so could result in holes in you tip, which ultimately ruin your
iron. You should periodically clean your tip as you're soldering. This will make your solder connections look nicer
and will increase the life of your iron. To increase the life of your iron even more, we recommend using a brass
sponge instead of a regular one. Expansion and contraction of the tip, from the cool water, tends to wear it out
over time.
Now that we've covered proper soldering iron handling and care, let's go over how to properly use it. There is a
correct way to solder, and it takes lots of practice to master. Getting it right early on will make your soldering
experience a lot more fun. Be sure to follow these bits of advice while your putting your kit together.

10kΩ Resistor
How to Solder: Through-Hole Soldering
SEPTEMBER 19, 2013
This tutorial covers everything you need to know about through-hole soldering.
BROWN BLACK ORANGE GOLD BOTTOM q-ngncun
Locate the 10kΩ resistor.
If you look closely, it has a specific pattern of stripes on it: BROWN, BLACK, ORANGE, GOLD.
Note: The patten can be in the opposite order; this is still the correct resistor. To further understand resistor
markings, please check out the following tutorial: Decoding Resistor Markings.
Bend the legs downward.
Locate the 10kΩ resistor position on the board
Insert the resistor into the PCB.
Push the resistor in so it is nearly flush with the board.
Note: This component is not polarized and so it does not matter which leg goes into each hole. Some
components in this kit are polarized and we will take extra care when we get to them to ensure they are
plugged in properly. These components will be denoted with a note and highlighted in yellow instead of
green:
Polarized
Component
Pay special attention to the component’s markings indicating how to place it on the PCB.
Polarized components can only be connected to a circuit in one direction.
To learn more about what it means to be polarized, please check out this tutorial: Polarity.
Slightly bend the legs outward to hold it in place.
Flip the board over. Hold the soldering iron's “Sweet Spot” so it touches both the leg and the metal ring. Hold for 2
seconds.
Feed solder into the joint.
First, pull away the solder. Second, pull away the iron.
Your solder joints should look like this - a tiny volcano.
Clip off any excess legs.
BOTTOM BOTTOM OF BOARD
Note: The resistor tells the microcontroller not to reset once the power is turned on, so your game can
continue uninterrupted. Try to be gentle with the board, but a few scratches are not a big deal.
Capacitors
Locate the two 0.1uF decoupling capacitors. These look a little different than resistors. They have two leads than
come down off the bottom of the component, and they have the markings “104” on them. (also note, the bottom
side may have some other letters, like “K5M”). They look like this:
Locate their positions on the PCB:
Insert the capacitors, flip the board over to the bottom side, and solder the pins just like the resistor.
Note: The decoupling capacitors help "clean up" the power on the board.
Microcontroller
Polarized
Component
Pay special attention to the component’s markings indicating how to place it on the PCB.
Polarized components can only be connected to a circuit in one direction.
Very impunam Make sure to afign me Hutch here. Ixxxxrxxxxxx‘ BUTTON BOTTOM OF BOARD
Locate the microcontroller. This component is polarized, which means we need to take extra care to place it in the
board properly. Notice the notch on the image below.
Looking at the bottom of the board, insert the microcontroller . Make sure that the notch on the chip aligns with
the white silkscreen on the board. To avoid having it inserted backwards, we cut off a pin.
Flip the board over and solder all of the microcontroller's pins to the board.
Note: The microcontroller is the brain of the game. It's programmed to light up the buttons and create the
game sequence. Bending the legs won't hurt the chip. It is designed to withstand the heat of the soldering
iron as well as gentle bending.
Buzzer
Polarized
Component
Pay special attention to the component’s markings indicating how to place it on the PCB.
Polarized components can only be connected to a circuit in one direction.
Locate the piezo buzzer.
BUTTON .spangunmm BOTTOM OF BOARD
Locate the position on the PCB. Note the “+” on the buzzer . The “+” on the buzzer should align with the white
“+” on the board.
Flip the board over and solder the buzzer's pins.
Note: The buzzer makes the noise for the game - pretty simple!
LEDs
Polarized
Component
Pay special attention to the component’s markings indicating how to place it on the PCB.
Polarized components can only be connected to a circuit in one direction.
Locate the four LEDs.
00 Bauerg 000 g 5 0:0 §5uund TOP OF BOARD
The LEDs are polarized. This means there are “-” and “+” legs. Each LED has a short leg and a long leg. The
short leg goes into the hole labeled “-”. Locate their positions on the PCB.
Insert the four LEDs into the top of the board. Also, make sure it sits flush with the PCB. Then solder them into
place.
Note: Light-emitting diodes (LEDs) are like light bulbs, but much smaller and more efficient. While the polarity
of the LED matters, the position of the colored LED should not affect the overall functionality of the Simon
game. If you are interested in placing a specific LED at a certain position, try testing the color of the LED with
a multimeter set to measure diodes.
For more information about polarization with LEDs, please check out this tutorial on Diode and LED Polarity.
Battery Clips
mmww Simon Sags TDD TOP OF BOARD
Polarized
Component
Pay special attention to the component’s markings indicating how to place it on the PCB.
Polarized components can only be connected to a circuit in one direction.
Locate the four battery clips.
Locate their positions on the PCB. Insert the battery clips . Make sure clips point toward each other so the
battery fits.
Ensure clips are flat against the board. Then solder from the bottom of the board.
Switches
Locate the two slide switches.
Simon Sags TOP f +lo o ‘ 0 Q . o o A L mugs- ass-w- TOP OF BOARD
Locate their positions on the PCB. Looking at the top of the board, insert the switches. Keep the iron tip away from
the black plastic! Plastic melts easily.
Flip the board over. Then begin to solder.
Note: The slide switches turn on and off the power and sound.
Final Assembly
Polarized
Component
Pay special attention to the component’s markings indicating how to place it on the PCB.
Polarized components can only be connected to a circuit in one direction.
Locate the button pad, bezel, screws, standoffs, and AA batteries. You will need to:
Attach the button pad to the top of the board. Make sure to lay the rubber button over the LEDs.
Attach the bezel over the button pad with notches for the screws pointing up.
Insert the screws through the bezel and button pad. Then twist standoffs onto the protruding screw. No
screwdriver is necessary. Hand tighten.
Insert the batteries , following “+” and “-” indicators on the board.
Insert the components as shown in the image below.
Note: Squishy buttons are fun! The bezel helps hold the buttons in place. The standoffs hold the board up off
a surface, helping to protect the electronics. They also hold the pad and bezel onto the board.
With that, you should have a fully functional Simon Says that you built yourself! Turn it on by flipping the “Power”
and “Sound” switch to the “On” position to see if it works.
If something is not working (i.e. an LED won't light up), please check out our troubleshooting section.
BONUS: Extra Fun!
Did you know that your Simon is much more than it seems? As an example of how the Simon is more than just a
game, we have included special features in the code. Just for fun, try this out. Don’t worry, it won’t change your
Simon permanently.
Turn the power switch to the “Off” position.
Press any one button.
While holding the button down, turn the Simon Says back on to test out one of the special modes that we have
included!
Troubleshooting BUTTON 1w 0'
Troubleshooting
If your Simon doesn't work right off the bat, don't fret. There are many ways that your board could have an error on
it. Look over these troubleshooting tips to help diagnose the problem. This section also goes over how to use the
solder wick that came with your kit. This is like an eraser for soldering mistakes, and it can come in very handy if a
mistake is made.
LEDs
LED(s) not lighting up even though you have a sufficient solder joint? Don’t fret, there is an easy way to fix it! The
most common cause of a failed LED is incorrect polarity. We have designed a special trick into the Simon PCB’s
design. You can simply cut the two traces and close two jumpers. This will swap the polarity without having to
remove the LED.
Using a hobby knife, cut both exposed traces directly over the white dots. To test, try using a multimeter set to
measure continuity to probe the trace between the pads and LED pins. This can help determine if the traces have
been fully cut.
Using a soldering iron, close both jumper pads with some solder. The image below shows an example of one of
the pads being closed.
Solder Jumpers
Did you accidentally solder a jumper between two legs where it should not be included? Don't fret. Here is a
simple process using solder wick to remove the excess solder.
Locate a solder wick.
Place solder wick on top of solder.
Place iron on top of solder wick. Hold for 3-4 seconds.
Once the solder begins to flow into the wick, pull the wick and iron away at the same time.
Resources and Going Further
Wrapping It All Up
I hope this has been a fun learning adventure. Soldering is a much easier than it may seem, and can be a useful
tool for many trades and hobbies. If you still feel like you need some more help you can check out the video below.
It goes over the same steps as are mentioned here, however, sometimes seeing someone else do it is easier than
trying to explain it.
Note: Please note that the video showcases a different version of the Simon Says, but it still highlights all the
main components and shows you the proper way to assemble them.
Bootloader Note: Reprogramming the ATmega328P Microcontroller w/ Arduino!
Building the Simon PTH Kit
Now that you’ve successfully got your Simon Says up and running, it’s time to incorporate it into your own project!
Arduino IDE
This ATmega328P comes pre-programmed with the Simon code as well as the STK500 serial bootloader. This
serial bootloader will allow you to re-program the Simon game using the Arduino IDE. Selecting the “LilyPad
Arduino w/ ATMega328” bootloader that was burned to the Atmega328P chip allows the Simon to be re-
programmed to do many different things! You can write code to change your Simon into a new unique project. Try
browsing our GitHub repository containing the default example code and additional examples:
