Introduction: Delay Timer Circuit
Today we'll discuss how you'll make an easy Delay Timer Circuit. the way the circuit works is that once you press the push_Button from then the load which is connected with the circuit will work. And after a while, the load will off. this is often the circuit during a nutshell.
How The Circuit Works?
The Delay Timer Circuit is connected with a 12V Power supply. When you press the push of the Delay Timer then Current flows from Vcc to GND through c1 Capacitor. For this, the Capacitor charges. Now once we unpress the Button then the Capacitor Discharges through the Mosfet's GATE Pin. So for this, the MOSFET became conductive.
As a result, Current flows from DRAIN to SOURCE Pin. As a result, the Load which is connected with the circuit is going to be Powered. In our case, we've Connected a 100w LED.
If you notice the circuit carefully then you'll see that we've connected a 100K Resistor parallel with the capacitor. The Resistor is for increasing the Discharge rate for the Capacitor. if you employ a better value resistor then the discharge rate is going to below and if you employ a lower value resistor then the capacitor discharge rate is going to be higher for Delay Timer.
In this way the On Delay Timer Circuit Works.

Things you got to realize off delay timer circuit?
This is an easy Transistor circuit with another complementary component. Here we are using an N-Channel Enhancement type Mosfet. as a result, the present output is far above a daily NPN Transistor. you'll use the other N-Channel Mosfet as you would like. IRFZ44n may be a quite common MOSFET so, during this project, I'm Using IRFZ44N Mosfet. Here the Resistor and therefore the Capacitor is connected in Parallel.
The Capacitor charges from the 12V Power supply and therefore the Resistor discharges the capacitor. if you employ higher values of resistor then the capacitor will discharge slowly. and if you employ a lower value Resistor then the capacitor will discharge in no time and therefore the Delay Timer Circuit will off in no time.
Indifferently, it can happen. Suppose you're choosing a typical value Resistor then you're varying the Capacitor. If you employ a better value capacitor with reference to an equivalent resistor then the capacitor will take much time to discharge. Now we all know the rule for Delay Timer Circuit that if we use a lower value capacitor with reference to an equivalent Resistor then the discharge is going to be faster compared to the primary time. So my point is that the Delay timer Circuit is often varied with the Resistor and therefore the Capacitor Value.
You can also attach a relay with the Load section of the Mosfet. Now the circuit is off delay timer relay circuit. You should not choose an excessive amount of lower value resistor otherwise the discharge rate is going to be too fast.
