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 ...

An Arduino Mega Pro Mini handles the logic, sending PWM signals to a DIY servo. The chassis consists of a modified Crazy Cart, selected for its absurdly tight turning radius.

This project demonstrates how to create an anti-sleep alarm system for drivers using an Arduino Nano and a Relay Module. The system detects signs of drowsiness or fatigue in the driver and triggers an ...

The part list consists of one Arduino, two resistors, and one IR emitter. That’s right, an emitter. When an LED (IR or otherwise) is reverse biased it can act as a light sensor.

For patients to receive good care, doctors must be present. To administer medication or provide treatment, he can’t be everywhere at once. If we regularly examine our health, we may be able to ...
