Title is not very descriptive because of problem starting new thread
Im using a circuit I found here in another post (see attachment) to measure the current from a solar panel and feed that data to an analog input of an Arduino.
The panel produces about 1 amp max resulting in about 100mv across the sense resistor and this is pretty small to get any kind of resolution out of the Arduino so Id like to amplify that voltage to 5V as 1 amp flows through the sense resistor. I was thinking of using something like an LM 358 opamp (Im planning on powering it with 9V so I dont have a + and supply) in a non-inverting configuration but Im not sure how to design the circuit.
Id appreciate any help on this or a better idea if someone has one.
Thanks in advance,
Tom
