Stap 2: Arduino code
De volgende code uploaden naar je arduino:

U kunt ook 3S LiPos (11.1V) meten door spanning door 3, 4S LiPos (14.8V) te delen door het delen door 4 enz.
Dit is het, geniet van uw nieuwe LiPo voltmeter!
Het beste ding is, je Arduino een heleboel andere dingen kunt doen terwijl het ook toezicht houden op uw LiPo!
