I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

This Arduino project simulates a proximity-based LED system using an IR sensor in TinkerCAD. It lights up the LED when something (like a hand or mouse) comes close to the sensor, and blinks the LED ...

This project uses an IR obstacle sensor to trigger an LED and an MPU6050 accelerometer to control a servo motor. All sensor values are displayed on both the Serial Monitor and a 0.96" I2C OLED display ...
