Interfacing Photodiode with Arduino: Uses a photodiode to detect light intensity and convert it into a voltage signal. Interfacing Servo Motor with Arduino: Controls the angle of a servo motor using ...

This Arduino C++ code implements a simple automatic door system using a servo motor and a motion sensor. The servo motor controls the opening and closing of the door, while the motion sensor detects ...

This research aims to develop a RADAR system using an ultrasonic sensor (HC-SR04), servo motor (SG90), and Arduino UNO. This RADAR system can detect objects in the vicinity and display information ...
