hi,
As pointed out by agu,the 10uF are reversed, if you apply 9V to the board they could explode.
Why have you started such a complex project without first getting the basic knowledge regarding components.?
I would suggest if you are interested in building projects you start studying basic electronics.
This is not intended as a 'put down', but doing this project by asking every simple step without understanding each step will not help you to learn.
If you feel you must proceed with this project, forget for the time being the clamp, the AD763 and the PIC and complete the CA3140 amplifier.
You can use a pot as a mVolt dc test source.
Once you have got that working, program the PIC to read the voltage coming from the CA3140.
