ic555 adjustable duty cycle flasher PCB

This circuit of IC 555 as adjustable duty cycle flasher is unique. It uses the trick of charging the timing capacitor C1 through two different paths of resistors R2 and R3, via two independent diodes D1 and D2. Working When power supply is connected to the circuit (9V, PP3 battery) the timing capacitor C1 starts charging Read More
