- How to test 555 timer ic using multimeter
This video is about NE 555 timer IC.In this video I explain how we can check NE 555 ic using Digital Multimeter.After watching this video you will be able to check an IC whether it is Functional or Not.
Hi sir firstly thank you for this helpful vedio , i want to share my experience with checking 555 timer ic so i have the same case and values of the 2nd ic but when i make the circuit the ic work perfectly so i want to say if you have an ic you need to check it with a circuit dont rely just to the multimeter cheching , best regard !
very excellent👍
what do the numbers mean? i can see that bad numbers are way bigger, but why does that mean they are broken
why do we connect positive terminal to the ground pin?
Helpful - thank you
یک روش دیگر هم هست.
مقاومت بین پایه های ۱ و ۵ باید حدود ۱۰ کیلو اهم و مقاومت بین پایه های ۵ و ۸ باید حدود ۵ کیلو اهم باشد.
Good 👍
And 1-8= 15K
@@SparkMind1what if it is olny 14.33k?
Thanks for the video. But why, the values of IC number 3 makes it damaged. For IC number 2 I understand that it is damaged because there is a reading which did not give a value. Thank you for answering my question.
My friend, IC 555 consists of resistor and transistor.If its values change, it is no longer IC555 And it turns into a new IC. So it is not defective, but it no longer has the necessary functionality.
@@SparkMind1 bro doesnt know wat his own video is about smh
So what is the conclusion?
I showed the result at the end of the video
The internal diagram of this IC can be found by typing "555 internal circuit".
@@SparkMind1 you didn't explain why those other two were bad and what are the standard numbers we should be looking for in order to know if any pins are off.
