This project demonstrates how to interface an IR sensor module with an Arduino UNO along with an LED and a buzzer. The IR sensor contains an infrared transmitter and receiver that detect reflected ...
An Arduino Uno guards a running 12 V motor. It watches for a person coming too close, overheating, abnormal vibration, a tilted machine and a jammed shaft. When something is wrong it slows the motor, ...
Role in this project: the controller. It reads every sensor, runs the state machine every 100 ms, drives the relay, the motor driver, the LEDs, the buzzer and the LCD, and talks to the PC over USB.
Role in this project: the MPU6050 and the LCD share two wires. The LCD shows the state, the reason for any stop, and live readings at the machine itself, with no PC needed.
If you wanted to make a game that ran on a commodity microcontroller, you could be forgiven for not knowing where to start.
