The R2 resistor is attached to the C1 condenser in series, allowing the RC circuit. The 12v regulator’s output is connected to the IC 555 Timer’s VCC and the regulator’s ground is connected to the 555 Timer ground pin. I used a 12v LM7812 regulator, as you can see. But as a 12v converter can be conveniently configured, I will use 12 volts.

The Vcc can be up to 16 volts, as you know. Now let’s look at the diagram of the circuit. In projects where you don’t want to use the expensive controller boards like Arduino and Mega, this Power-ON delay circuit can be really beneficial. You can also use the circuit I’m going to explain with the PIR, Laser, Push Buttons etc. This 555 timer-based delay circuit can also be used for turning the buzzer ON in the security systems for a certain period of time that can be calculated using the formula discussed above. The aim of this project is to turn on the load any time you press the button or activate a sensor for a few seconds. In this project, the Monostable Mode uses the 555 Timer IC. The 555 Timer Power-ON delay circuit can be used in various projects where for a certain amount of time you need to turn on a specific load. I would appreciate your support in this way! 555 Timer IC-based Projects: 555 Timer Power-ON delay circuit: I may make a commission if you buy the components through these links.
