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 ...

Apart from the Arduino UNO, the circuit consists of two more primal ... performance will depend on many factors, including sensor orientation, object size, shape, color, and reflectivity. Back to the ...

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 ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

This is how this basic circuit works. Now that we have ... because in this project we have used an Arduino and a sound sensor to build a musical fountain that will generate aesthetic design with water ...

The voltage divider can be paired with an operational amplifier to design the ideal light or dark ... connect LM358 ‘s pin 7 of to one of Arduino’s digital I/O pins. As a dark sensor, the circuit will ...

The circuit components are 2 Arduino Uno, 6 servo motors, 1 ultrasonic sensor, a breadboard, and a 9V battery. The coding is done in a way that turns the servos to an angle of 90 degrees and when an ...

If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller that lights an LED to alert the user when it is time to water a potted ...

Another example illustrates an implementation of the heartbeat pulse sensor to emphasize how useful ... The paper discusses how Arduino has emerged as a pivotal tool in electronic circuit design, ...

To test the circuit, you need to connect the sensor, the output device, and the Arduino according to the schematic diagram. You also need to upload the code to the Arduino that reads the sensor ...
