DIY Arduino Capacitor Tester

[@philipsmith4037]

Nice walkthrough, it’s very helpful for beginners to have a walk through of the code like this.

wouldn't it be better to start with a DISCHARGE cycle first? A partially charged cap would reach the 62% point faster thus giving wrong results. Maybe this is what happened with the "faulty" 100uF that measured as 50uf... Nice project.

+mamoynas Yes it would.

Would it detect if you connect the capacitor with the wrong polarity?

[@learnelectronics]

+HobbyTime No it's a dumb detector.

learnelectronics thanks a lot for aswering It is great any way. I am wondering how to test polarity. Thanks!!

Hi, How would I edit your code and only use serial no lcd?

Where I can download code..?
