You’ve ordered an Alien Transceiver in order to communicate with your intergalactic neighbours. Unfortunately, the device is not set up yet; to activate it, you have to adjust the climate in your room. Without any screen, the physical game challenges you to press buttons, turn knobs, adjust the lighting and room temperature, so you can start receiving signals. The final signal points to the beginning of another game: AlienSignal by Pixdigit
Arduino IDE (https://www.arduino.cc/en/Main/Software), Arduino Arduino Uno, Half-Breadboard, Pushbutton, Rotary Potentiometer (small), Piezo Speaker, Photocell (LDR), Temperatur Sensor, 3 red LEDs, 2 Resistors (10kΩ), 3 Resistors (33Ω), 22 Jumper Wires
In order to be able to play the game, you have to compile and copy the Arduino code onto an Arduino microcontroller as well as build the circuit yourself. A schematic is provided in the source files.
