Positive pin to ground and the negative pin to positive through a resistor not less than 10K. Take the output to lm124 from the point where the negative pin of photodiode joints with the resistor. GND +pin photodiode – pin —- 10K resistor VCC | | LM124 Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
