Colour Game Case

COLOUR GAME is a small standalone RGB colour matching game built around an Arduino Nano ESP32 and a custom 3D printed case.

The idea is simple: the player connects to the device over Wi-Fi, opens the local game page on their phone, and then tries to recreate a randomly generated colour using the physical RGB buttons on the device. Once happy with the colour mix, the player submits their guess and compares it against the target colour.

The case was designed specifically for this project to make it feel more like a finished handheld gadget than just exposed electronics. It includes large front-facing buttons and 3 LEDs used for mixing and displaying the colours during gameplay.

The device creates its own Wi-Fi network, so everything runs completely offline with no router or internet connection required.

The code for the project is available on GitHub here: https://github.com/robroy865/colourgame

Part List:

• Arduino Nano ESP32 (x1)
• Red LED (x1) — with 100 ohm resistor
• Green LED (x1) — with 220 ohm resistor
• Blue LED (x1) — with 150 ohm resistor
• Momentary push buttons (x4) 
• Resistors: 100Ω, 220Ω, 150Ω (one each for the LEDs)
• USB cable (to power/program the Nano ESP32)
