The circuit was designed to create a touch switch that can be used for ON/OFF functions in modern technology. BC547 – NPN small signal transistors designed for general purpose switching and ...
This voltage-booster circuit for driving one or more white LEDs uses a 555 timer as its main element (see the figure). The timer, IC1, functions as a resettable astable multivibrator where R1, R2, and ...
This ON OFF touch switch circuit is based on the well known timer IC 555 (IC1), which drives a relay that acts like a switch. The metal surfaces can have what form we want, but it should be clean and ...
