These on off intervals can be adjusted by varying the 555 timer output and number of counter outputs. The project adjustable dual timer circuit using 555 timer ic is also one of the applications of 555 timer ic. This circuit uses very basic components like 555 timer and 4017 counter.
This electronic timer circuit is helpful when you need to power on off any ac appliances after a pre defined duration.
Adjustable on off timer using 555 astable mode in this circuit a timer with cyclic on off operations is designed. By adjusting the values of external resistor r1 and capacitor c1 adjustable timer circuits can be designed. These on off intervals can be adjusted by varying the 555 timer output and number of counter outputs. The time period is set by adjusting the variable resistor.
