The key to a simple circuit works simply by touching the sensor circuit is effective andexcellent in several applications
And easy construction

Circuit diagram

Explain the circuit

Working principle of the circuit simply by touching the sensor will give a glass
The oscillator circuit consisting of gates and deny the intense resistance which gives the oscillator circuit
Pulse output of the square and where the LED and intensive transfer of the signal pulses
ac to dc voltage constant is passed to the base of the transistor, which makes the transistorin
If you have connected and thus completing the circuit and pass the operating voltage ofpregnancy
