Simplest Clap Switch Circuit
Circuit Diagram and Working Explanation: The circuit diagram of the clapper circuit is shown in below figure: Clap Switch using Arduino ARDUINO 21 Clap Switch using Arduino 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. This Clap ON Clap OFF switch basically turns ON or OFF the device, by using the clap sound, as switch. We have previously built Clap switch and Clap ON Clap OFF switch , using 555 Timer IC. On clapping there will be a peak signal at the MIC which is much higher than normal, this signal is fed to the amplifier, though a High Pass Filter. This amplified voltage signal is fed to ADC, which converts this high voltage into a number. So there will be a peak in the ADC reading of the UNO. On this peak detection we will toggle an LED on the board, ...
