Turn your Arduino Uno into a fun, portable "Simon" style memory game. This kit is a perfect way to practice beginner soldering skills, and includes with all the parts that you need to build this Arduino Uno shield.

You can find the complete code for the Simon game on GoodArduinoCode.com and on GitHub.

Note: the kit in the first photo with the cat graphics is an older version, you get the new version with the Wokwi logo.

Connection Diagram

The diagram shows how the components are wired in the shield PCB:

• The LEDs are connected through a 220Ω resistor each.

Kit Contents

What you get:

• 1 x Simon Game Uno Shield PCB
• 4 x LED: Red, Green, Blue, Yellow
• 4 x 12mm Tactile Push Buttons with Caps: Red, Green, Blue, Yellow
• 4 x 220Ω Resistor
• 1 x Piezo Buzzer
• 1 x 10-pin Male Header
• 2 x 8-pin Male Header
• 1 x 6-pin Male Header

What you need:

• Arduino Uno (or compatible) board
• USB cable (to program the Uno board)
• Soldering iron and solder (for assembly)
• Wire cutter (to cut the leads of the components)

Assembly Guidelines

To make assembly easier, it's advised to begin with the lower-profile components first. Polarity is only important for the LEDs, the other components can be assembled in any direction.

Here is the recommended soldering order: 1. Solder the four 220Ω resistors 2. Solder the Piezo buzzer (the black part) 3. Solder the 4 LEDs, paying attention to their polarity (see below) 4. Solder the 4 Tactile Push Buttons 5. Flip the board, and solder the pin headers (see below).

Make sure you pay extra attention to orientation of LEDs, otherwise the LEDs won't function! The longer leads should be where the white circle is curved, facing AWAY from the WOKWI logo. The red arrows in the following photo indicate where you should put the longer lead of each LED:

When soldering the pin headers, it's recommended to place the board on top of an Arduino board. This helps to solder them straight. The longer part of the pins should go into the Arduino board, and the black plastic should be between the Arduino board and the Simon Game Shield PCB:

After assembling, cut the protruding leads of the LEDs and Resistors. You can also cut the end of the leads of the buzzer and Push button (one of the Push button may touch the USB connector on your Uno board, so it's necessary to either cut its leads or mask them with some masking tape).

After you finish soldering, upload the game code to your Arduino Uno board, plug-in this shield and... you are ready to play! Can you beat my high-score of 20 points?
