A switch is the most essential part of any circuit. Different circuits use different switches in them. In this project, we are going to use a Touch Dimmer Switch. This switch is a touch-sensitive ...

This sensor device is built to measure the amount of current being used, especially in power supplies as the design is based on Arduino. The main component used is the ACS712 sensor from Allegro ...

In this tutorial we discussed the Sound sensor, its pinout, working, and how to interface it with Arduino. This article includes a complete Arduino code and circuit diagram along with a step-by-step ...

In this project we are making a Light Sensor using LDR with Arduino to control a light bulb/CFL as per light condition of the room or outside area.

This project demonstrates the design and programming of an electronic circuit using the LM35 analog temperature sensor with Arduino. The circuit reads temperature values from the sensor and displays ...

Learn the skills and tools needed for sensor and actuator hardware design. Explore the concepts, process, software, hardware and resources for this field.

To use a dark sensor instead, connect LM358 ‘s pin 7 of to one of Arduino’s digital I/O pins. As a dark sensor, the circuit will output as HIGH when it’s dark and a LOW when there’s light. The output ...
