- In this video, I've explained 555 Timer IC with the pin diagram and the internal circuit diagram. In this circuit, we have four basic blocks, these are
1. Voltage divider by resistor block
2. Comparator block
3. SR flip flop
4. Discharge and output circuit
I've also given the explanation each and every pin except pin number 7.
For the pin 7, we have to add external device like capacitor and resistor. In Astable mode of IC555 video, I explained that.
Pins of IC 555
Pin number 1: Ground
Pin number 2: Trigger
Pin number 3: Output
Pin number 4:. Reset
Pin number 5:. Voltage Control
Pin number 6: Threshold
Pin number 7:. Discharge
Pin number 8: Vcc (4.5 volt to 15 volt)

Comparator of less then 4volt of pin 2 , how ur telling comparator output is high
Incisive explination!!
Loved it
Thank you so much 😀

There is a way of calculating the frequency of an astable circuit using a chart called a nomograph and cannot find any explanation of how to do this and would love to see a video with a step by step explanation of how to use this chart.
Could you please provide a link for this chart? I'm not able to find it.
@@EEWave here is another link and they all say the same thing but don'r show how to use it or i'm just not understanding how it is done. docshare01.docshare.tips/files/25701/257011035.pdf
Thank you 😊.
Now I will make two videos with nomograph.
1.Monostable
2.Astable.
@@EEWave thank you so much and here is a link to astable nomograph. www.555-timer-circuits.com/astable-multivibrator.html
Sir how we know that the Resistance value is 5 ??
Cuz it is named 555 timer....based on 3 resistance that is 5 k-ohms
your schematic is wrong in a few places. qbar is output and there is an inverter on the output at pin3.
Supper anna
Thank you Macha

Brother I know that Q bar is the out put ....will u see and tell me
I'm sure that it is correct. Please refer other books and videos. And don't forget to watch the theoretical and practical video on monostable mood, you will get your answer, link in the description below. I'm sure this will help you. Thank you sister. 😀
make a mega Arduino tutorial with a 12volt led power supply 12 volt battery
😍
Glad you think so!
Please watch my Monostable and Astable mode of 555 timer IC explanation, link in the description below. I hope it will be helpful to you..!
Totally wrong.... output need to take at Qb
Explain please
Already I mentioned it in above comment
@@Kanishma658 but why he explained like this. .. through Q we get discharge pin but he took from Qbar ...he took reverse SR flip-flop
I'm sure that it is correct. Please refer other books and videos. And don't forget to watch the theoretical and practical video on monostable mood, you will get your answer, link in the description below. I'm sure this will help you. Thank you bro. 😀
