Scaffolding: Mapping - NeoMemory

We created a small interactive game using the Adafruit Circuit Playground that combines a button, a potentiometer, a light sensor, and NeoPixels. The game starts when the player presses a button connected to A3. Once the game begins, a short animation plays where one NeoPixel lights up red and then turns off. This red light represents the target position the player needs to remember. The player uses a potentiometer as a controller (A2). We map the potentiometer’s analog value to numbers between 0 and 9. Each number corresponds to one of the NeoPixels, and the selected pixel lights up blue to show the player’s current choice. This gives clear visual feedback while turning the knob. When the player thinks their selected position matches the red target, they press the light sensor to confirm their answer. If the selected position is correct, the player moves on to the next round. If it is wrong, the game immediately resets. Each time the player gets a correct answer, the animation becomes longer, adding one more red light to remember. The player must correctly match the pattern four times in a row to win. If the player wins, all the NeoPixels light up green. If they lose, all the lights turn red before the game restarts.
