Using the multimeter, you can (safely) confirm connections and polarities before applying power to a circuit. Perhaps it is time to purchase a low cost digital multimeter. While I cannot point you to a specific tutorial, the most important part of wiring power is to get the polarity correct. Ideally something small is better, I want to fit the whole thing in a Altoids box. I'm not sure whats the best way to power this up, in 'efficient manners' should I go for a rechargeable battery? Some button batteries? AAA ones?

This type of sentence doesn't make me want to do a bunch of 'try and error' tests The most scary aspect is when you ready: 'Oh and be careful, if you're doing it wrong, it's gonna blow up'. I very recently got into electronics, and I found a lot of 'beginner''s tutorials which were fantastic.Īnd a lot of 'very advance ones', sadly I'm king of missing the middle partĮspecially when it comes down to powering up an Arduino with a rechargeable battery or using AAs.
