Attiny85 Battery Tester

Projects General Guidance
18

  • You need to measure the voltage at pin 3 of the ATtiny85 with a multimeter.
    (do you have one?)

  • You then need to download the sketch again.
    (I recommend saving it this time - it might come in useful).

  • Modify the sketch by adjusting 'FACTOR'.

  • Reprogram the ATtiny85 with the modified sketch.

  • Test to see if the results are acceptable.

  • If still not correct make further adjustments to 'FACTOR' and re-program etc.

We will help you further if you get stuck, but we would need to see the sketch to do so.
