10 Minute Timer Circuit | Using 555 Timer IC.

Hello friends, how are you all? I hope you are well. I am also well by the grace of Allah. In today's post, I will show you the complete process of making a 10-minute timer circuit using the 555 timer IC.

Edited with Canva.

In today's circuit diagram, by using the 555 Timer IC in Monostable Mode, when a push button is pressed, the circuit generates a timing pulse of about 10 minutes. When the time is up, the output signal is displayed through the LED.

Components used and their functions

Serial	Component	Value / Type	Function
1	555 Timer IC	–	Maintains timing, controls output and handles discharging.
2	Resistor R4	2.2MΩ	Sets the timing period.
	Resistor R5	500KΩ (Variable)	Allows for increasing-decreasing the time period.
3	Capacitor C2	150 µF	Charges and discharges to create a delay of about 10 minutes.
4	LED D1	Power LED	Indicates whether power is being supplied to the circuit.
	LED D2	Output LED	Indicates whether the timer is active or expired.
5	Push Button S1	–	Used to start the timer.
6	Battery	9V	The main power source for operating the circuit.

Now I am showing the process of drawing the entire circuit in 5 steps

In the first step, you can see that I have created the diagram through software, and here I have taken a 555 timer IC. First, we have taken a 9-volt power supply, which you can see on the right side of the hand. From there, the positive line IC 8 number pin has been, and the number 1 pin is the ground, which is connected to the ground with the minus. Then a capacitor is connected to the pin number 5 control voltage, and the minus part of the capacitor is connected to the ground, and you can see the value of the capacitor in your picture.

Step -02

Now you can see that a 10k resistance has been placed with the reset pin number 4. And pin number four is connected to pin number 2 of the trigger. And to restart the trigger, an on-off switch is used here, and it is connected to ground.

Step -03

Now you can see that pin number 7 discharge and pin number 6 threshold are connected together, and from there a capacitor of 150 uf is placed, and the negative end of the capacitor is connected to ground.

Step -04

Now you can see that two 330-ohm resistances are placed with pin number 3 output and an LED is placed with pin number 8 positive. And another LED is placed from the resistance number two and connected to ground. Here one LED will work as power and another LED will work as timing.

Step -05

Now you can see that to change the mode timing of the last one and to increase the time, a 2.02M resistor has been installed with pin numbers 6 and 7, and above you can see a 500K variable resistor has been installed and then connected to the positive.

A few words from me.

I was out of work for a long time due to my health condition, and today I created a diagram through simulation software, and I am not able to show its output. Because it is paid software, to show this output I have to buy the paid software for 15 dollars. But I wanted to buy it; unfortunately, there is no country region to buy this software from Bangladesh. So I am not able to buy this software from Bangladesh, and I am not able to start the real simulation.

🟩 Thank you for reading my post and giving your valuable time. Stay well and stay healthy. God bless you. 🟩
