In the circuit given in the url, can anyone check for me how is C4 connected?I use a 9V battery,should i connect its negative straight to the ground or to the C4 before it goes to ground?This circuit looks simple but i find it confusing
Thank you very much mr mike,Another question i would like to know …are all pin photodiodes the same?can i use a pin photodiode of a different type for this circuit?
