This project for Arduino 2-Step Programmable Timer Circuit with Independent Output Delay Adjustment uses Arduino microcontroller to make simple timer. Not like normal timer with two outputs as this one uses only one output. It switch between two states. And each state have delay which we can change for different use. Circuit Working: Parts List: […]
Timer Circuits
Power ON Delay Circuit
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 […]
AC Power Outlet with Timer Circuit
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 […]
Automatic Power Delay OFF Circuit
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 […]
Simple 220V Time Delay Switch Circuit with Triac
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 […]
Timer Circuit with Alarm using IC 4060
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 […]
