I am currently working on a team that is using the Arduino to read in measurements of current and voltage from a small solar cell. We are currently in the testing phase, and using an Arduino Uno board. Below is the circuit and schematic we came to a consensus of implementing that met our specifications. Right now, my biggest question is how to wire the components to the right inputs on the op-amp to the correct outputs for the Arduino. We plan on having a load connected to have the Arduino capable of reading the current across the circuit.
I am currently a novice, as this is my first time designing a circuit for a specific application so any input would much appreciated. Thanks!
