The code for the Arduino battery tester is straightforward. We take a reading from the analog input and convert it to a voltage. We then compare this to our defined values and turn the relevant LED on.

To test it out, turn the Arduino on and then hook the analog wire to the positive end of the battery and the negative wire to the negative end. Once hooked up, the Arduino should light up the relevant LED. If it doesn’t, you will need to do some troubleshooting.

I hope that you find this Arduino battery tester tutorial helpful.
