Touch On-Off Sensor Switch Circuit on Breadboard | IC 555 Timer project #1

A tutorial on how to make a Touch Switch / Touch Sensor circuit on breadboard using 555 timer IC. An explanation of how this circuit works is also included in this video.
AC appliances or any high loads can be controlled with just a touch of your finger by using a relay in combination with this circuit.

Components Required:
555 Timer IC
1 or 2 LED's (You can also connect buzzers etc.)
Resistors 2 x 10M, 2 x (The series resistor for LED's)
Breadboard
Few Breadboard Connectors
(5-12)V of DC power supply

This touch on touch off switch circuit requires two pairs of touch contacts for it to turn on & off the output. In the upcoming video we'll make a circuit that requires just one pair of touch contacts. So stay tuned.

This channel has a lot more electronics projects & 555 timer projects. So feel free to check them.
