This project controls a relay module using an Arduino, providing both automated timer-based operation and manual override functionality via a button. The system is designed for applications where a ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

A 5V single-pole, double-throw (SPDT) relay used to control the load (230V AC, 60W bulb) acts as a switch. The 5V power supply is connected to the 5V (Vin) and GND pins of the Arduino Nano to enable ...

Proximity Sensor Switch – Circuit Diagram. The circuit diagram of the wireless load control unit is shown in Fig. 2. This design is based on Arduino Nano board and built around an I2C LCD (module1).

This study focuses on the development of an obstacle avoidance robot controlled by an ultrasonic sensor. The robot utilizes robotics and artificial intelligence techniques to improve obstacle ...
