Web14 de jul. de 2015 · So to build 1 minute (60 seconds) timer we need resistor of value 55k ohm and capacitor of 1000uF: 1.1*55k*1000uF. (1.1*55*1000*1000)/1000000 = 60.5 ~ 60 seconds. A variable resistor of … Web5 de jul. de 2024 · Working Explanation. This circuit is operating at 9-12V DC. To set the time delay of our circuit we have used an electrolytic capacitor Cx, if you want a time delay of a few seconds to use 10µF, for a delay of 2 minutes use 100µF, and so on. We have connected a switch at the input pin (pin 2) of the 555 timer IC, so when the switch is …
