Arduino Touch Sensor Relay Circuit

Last updated on 4 July 2026 by Admin-Lavi Leave a Comment

Want to control appliances by touch? then this circuit makes it possible, as this Arduino Touch Sensor Relay Circuit uses Arduino and touch sensor. The Arduino reads the touch signal and uses the relay as a toggle switch. When we touch the sensor once, the relay turns ON and when we touch the sensor again, […]

Arduino Sine Wave Output Circuit with RC Filter

Last updated on 2 July 2026 by Admin-Lavi Leave a Comment

This project show how to make simple Arduino sine wave circuit with RC filter; as Arduino cannot give real analog output, but it only gives PWM signal. So we use low pass RC filter to change PWM into smooth sine wave; also two potentiometer control amplitude and frequency, therefore, this circuit is very easy and […]
