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.

Solder to Iron

Here's a close up of the solder once the solder is able to melt on the soldering iron tip.

Closeup Solder on Iron

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.

Iron In Stand

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.

Cleaning Soldering Iron

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.

How to Solder: Through-Hole Soldering

September 19, 2013

This tutorial covers everything you need to know about through-hole soldering.

Quickstart - Your First Component

We'll go over over in detail how to solder on the first part. Then we'll show you which parts go where and let you have at it. The booklet that comes with the Simon Says has been carefully crafted and goes over the assembly in lots of detail. We'll follow along here. Click on the image for a larger view, or you can download the entire guide here.

10kΩ Resistor

Locate the 10kΩ resistor.

10kOhm Resistor

If you look closely, it has a specific pattern of stripes on it: BROWN, BLACK, ORANGE, GOLD.

Color Code for 10KOhm Resistor

Bend the legs downward.

Legs Bent

Locate the 10kΩ resistor position on the board

Bend Resistor Legs

Insert the resistor into the PCB.

Find Resistor's Position on PCB

Push the resistor in so it is nearly flush with the board.

Resistor Flush

Slightly bend the legs outward to hold it in place.

Bend Legs Apart

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.

Heat Through Hole

Feed solder into the joint.

Feed Solder Joint

First, pull away the solder. Second, pull away the iron.

Pull Solder and Iron Back

Your solder joints should look like this - a tiny volcano.

Ideal Solder Joint

Clip off any excess legs.

Clip Excess Legs

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:

0.1uF capacitors

Locate their positions on the PCB:

Capacitor Location

Insert the capacitors, flip the board over to the bottom side, and solder the pins just like the resistor.

Microcontroller

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 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.

Atmega328

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.

Locate Atmega328 on Board

Flip the board over and solder all of the microcontroller's pins to the board.

Buzzer

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.

Buzzer

Locate the position on the PCB. Note the “+” on the buzzer . The “+” on the buzzer should align with the white “+” on the board.

Buzzer Position

Flip the board over and solder the buzzer's pins.

LEDs

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.

LEDs

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.

LED Position

Insert the four LEDs into the top of the board. Also, make sure it sits flush with the PCB. Then solder them into place.

Battery Clips

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.

Battery Clips

Locate their positions on the PCB. Insert the battery clips . Make sure clips point toward each other so the battery fits.

Battery Clip Positions

Ensure clips are flat against the board. Then solder from the bottom of the board.

Switches

Locate the two slide switches.

Slide Switch

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.

Switch Position

Flip the board over. Then begin to solder.

Final Assembly

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.

Final Assembly

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.

Assembled Simon Says

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.

Switch Off

Press any one button.

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.

Close Up Simon PCB's 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.

PCB Hobby Knife

Using a soldering iron, close both jumper pads with some solder. The image below shows an example of one of the pads being closed.

Close jumpers

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.

Solder jumper

Locate a solder wick.

Solder Wick

Place solder wick on top of solder.

Wick on Solder

Place iron on top of solder wick. Hold for 3-4 seconds.

Iron, Wick, Solder

Once the solder begins to flow into the wick, pull the wick and iron away at the same time.

Pull Wick and Iron Away

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.

Bootloader Note: Reprogramming the ATmega328P Microcontroller w/ Arduino!

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:
