Electronic Timer Circuit Diagram Simple Adjustable Timer Circuit with 555 IC. Using simple 555 timer we can design an adjustable timer switch. This circuit is flexible to adjust required time. Circuit Diagram Components. 555 timer; Electrolytic capacitor - 470 uf; ceramic capacitor - 0.1nF; Resistors 120k ohm 10k ohm; Relay -12v; Push button; Working An electronic timer circuit is an essential component in many electronic systems and devices. It allows you to control the timing and duration of various operations, such as turning on/off lights, motors, or other components after a predefined time interval. Timer circuits find applications in a wide range of fields, including automation, home This simple digital timer circuit can be used to obtain timing output through selectable ranges, which can be set from 0 to 99 second, with 1 second interval, 0 to 990 seconds with 10 second interval, and 0 to 99 minutes with 1 minute interval. All these timing outputs can be visualized and tracked through a 2 digit common anode LED display.
Note: You can also use the formula to make a timer circuit by changing the capacitor value and make the resistance value constant.
