Timer Circuits

Power ON Delay Circuit using IC 555 give time gap between power ON and circuit starts. When trigger comes, IC 555 work in monostable mode and give one output pulse for set time. Resistor R1 and capacitor C2 make timing part for delay. Output stay low with circuit OFF when capacitor is charging. When power […]

In this AC Power Outlet with Timer Circuit think about a normal plug goes in wall but this one have a timer built-in like small control panel. This is called a timer plug or outlet timer. We can plug other device into it. Inside, small chip work like a brain and it is called 555 […]

This Automatic Power Delay OFF Circuit is like small helper to remind us to turn OFF things. We can connect it with our device with the time frame like 1 hour, 2 hour as it stops the power by itself. It is very useful if we want to keep nightlight ON for some time or […]

Think this circuit is like a smart switch for our home things which wait for some time before power comes. This Simple 220V Time Delay Switch Circuit with Triac work like power button but it does not gives power fast. It waits for little time and then gives power to light, fan or motor. We […]

This Timer Circuit with Alarm using IC 4060 like small stopwatch which is having buzzer inside. It uses one chip named as IC 4060 and this chip count seconds like small clock. We can set time how much we want. When the time finishes buzzer make sound to remind like a kitchen timer. This circuit […]

Can anyone think small timer for their electric things? Simple Time Delay Relay Circuit work like stopwatch for power. It waits for some time before turning ON or OFF something like light or motor. This wait time can be same always like 5 second or can change using timer knob. Main reason to use it […]
