This code helps to control a servo motor using a touch sensor. You can connect the wires as below. Connect the touch sensor pin to D2 Connect the servo motor pin to D9 //below is the arduino code ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

This project uses an Ultrasonic Distance Sensor to measure the distance in front of the device. Based on the distance, it controls four DC motors and a servo motor to steer and rotate the device: 🚗 ...

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 ...
