Simple Touch Switch using transistors
Touch circuit diagram:
The purpose of this project is to trigger/switch AN diode with an easy bit. The skin’s resistance is concerning 1K. therefore if you are
Tiny electrical phenomenon flows through the skin once the top bit conductors area unit touched. this small current is amplified in magnitude by the primary and second transistors and it finally passes through the diode. discuss with the circuit diagram for higher understanding.
