The goal is to press the red button when the red LED is lit up. When you get a “HIT!” you get a point. Every 5 points increases your level. If you miss, you lose a point. This project uses the Arduino (ATMEGA328P) micro-controller.
Using an Arduino Nano (micro-controller), LCD1602 (display), 8 LEDs, a red push button, an external battery (power supply), a small speaker, a few resistors, a few transistors, and a ton of wires.
