Monostable Multivibrator 555 Timer IC Full Diagram & Simulation.

How are you all? I hope everyone is well and healthy by the grace of Allah. Today I will share with you the 555 Timer as a Monostable Multivibrator Diagram and Simulator.

Edited with Canva.

In today's post I am sharing a simulation of a simple circuit made using a 555 timer IC. I have summarised step-by-step how the connections have been made and the output has been tested. I hope it will give a clear idea for the beginners.

A monostable multivibrator is a synchronous or asynchronous sequential circuit that is widely used in electronic circuitry. When a negative pulse is applied to the input trigger pin of the IC, a positive rectangular pulse is generated at the output.

The trigger pulse produces a single output pulse. In short, we are going to design a monostable multivibrator using a 555 timer IC.

Parts Used

Name	Quantity	Component
U1	1	555 Timer IC
R1	1	100 kΩ Resistor
C1	1	47 µF, 16 V Polarized Capacitor
P1	1	12V / 5V Power Supply
D1	1	Green LED
R2	1	1 kΩ Resistor
C2	1	100 nF Capacitor
R3	1	10 kΩ Resistor
S1	1	Pushbutton

Now I will show you step by step how to make a diagram.

Step -01

First of all, I have taken the 555 IC. Then you can see that I have taken out the 555 timer IC pinouts, and I have taken the pins according to which one will be connected to which place.

Then you can see that I have placed a 100K resistance from the positive, then a capacitor of 47 uF 16 volts has been placed, then the connection to the ground has been given.

Then you can see that the number one ground PIN has been connected to the ground, and the number 5 pin has been connected to a capacitor, and again the ground connection has been given, and the value of the capacitor is 100 NF.

Step -02

Now you can see that the number 7 pin and the number 6 pin have been combined and the connection has been given between the capacitor and the resistance.

Then you can see that another line has been drawn from the positive connection, and it is given to the trigger pin number two. A 10K resistance has been given to the trigger. Then a push button has been placed from the second pin number, and the push button has been given to another connection ground so that the trigger can be turned on again and the output can be running.

Step -03

Finally, now you can see that from the output number 3 I have connected the LED with a 1K resistance and connected the minus end of the LED to the ground, and I will show this diagram through simulation software. So you can watch the video.

Here is a software diagram.
