Thanks for the response. had been away so could reply timely. You have given me alot to read up on and to understand.
A few other questions:
How do I determine the value of the voltage after the diode bridge that is going into the 4n25?
what is the need for the 10k resistor going to VCC
Well I do feel a bit out of my depth but lets see what I can figure out.
From what I can see 220v is applied through the bridge rectifier which converts it to DC, which is then fed through the opto coupler to detect the zero cross.
1) How does it detect the zero cross from a dc signal?
2)...
Thank you, that helps as well, knowing which topics to read up on.
Well I've never really been a physics student and tend to focus more on the coding side of things, so that's why I hoped to get an explanation of the the workings of the circuit to help my understanding and know what I should...
Could someone please provide me a little explanation on the workings of this circuit and how the components are used.
I have this project I would like to implement for school, but to be honest I lack a bit of understanding of it and would like to know a bit more why these components are used...
Hello I am required to make a simple program to interface hardware with one of the mentioned ports using c++.
I have decided to use a 7 segment display and display numbers that are inputted from 0 to 9.
I have not done a program like this before so if anyone can help me or point me in the right...
