ICl7107 Voltmeter problem

[[email protected]]

I've constructed icl7107 voltmeter, but it doesn't work. The display
displays "1666". What's up?

Obviously, you made errors in its construction, and most likely have
damaged parts.

What you are asking is for a fortune teller to to know what you did.

I would suggest to buy a discent volt meter, not build your own.
