Touch Sensor Using 555 Timer Project Report. Simple touch switch project using 555 timer ic. This is a very simple touch sensor switch that is build with the 555 timer ic.
If you re new to 555 ic please take the time to read our beginner s guide on 555 ic. In this project guide we re building a touch switch circuit using ne 555 ic. This simple touch switch is developed by using 555 timer ic operated as a monostable vibrator.
A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor.
Pin 5 of 555 timer ic is connected with a capacitor of 0 01 μf. Technical specifications characteristics supply voltage. Basically in this circuit we will have a led which turns on when we touch a pin of timer. Then connect another wire which goes from the positive side of the battery to pin 8 of ic.
