The complete circuit diagram for the Arduino Whistle Detector Switch circuit using Sound Sensor is show below. The circuit was drawn using Fritzing software. The Sound sensor and the Relay module is ...

In this project we are going to make Clapper circuit using the concept of ADC (Analog to Digital Conversion) in ARDUINO UNO. We are going to use a MIC and Uno to sense the sound and trigger a response ...

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 ...

Arduino based 4 channel toggle switch using 4 relays, 4 tactile switches, an Arduino Nano, the circuit required 12V DC, the relay can handle load up to 7Amps 230V DC or 7Amps/30V DC. - Arduino-4-ch ...

Due to the low current drawing, the circuit can be supplied from 230Vac mains without a transformer. Supply voltage is reduced to 12Vdc by means of C1 reactance, a two diode rectifier cell D1 & D2 and ...

When reed switch is opened, pin 2 of Arduino goes high with the help of the pull-up resistor R2, and the alert signal is available through the piezo-speaker PZ1 (not an active piezo-buzzer). At the ...

Switches: S1: Toggle switch: Circuit & Working. Circuit shown below operates using a minimum of 5V DC power supply ... The brain of the circuit is Arduino Uno MCU board (Board1). Three Ultrasonic ...

The circuit is shown active or “on” mode. Half of RL1 and RL2 manipulate the switching and the other is connected to an application. Relays are 200 ohms above ground and at one point are referenced to ...

For some of us, there are few sounds more satisfying than the deep resonant “thunk” of a high quality toggle switch slamming into position. There isn’t an overabundance of viscera… ...
