Circuits – How to Fix your Earphones

Shares

Today I’ve decided to share how to fix your earphones when they get a short circuit. This happens once in a while so I’ve thought this could be useful the next time this happens to you. This tutorial will be a bit different, It’s a step by step video. I hope you enjoy.

Arduino – Pull-Up Resistors

Shares

Today I’ll talk about Arduino built in Pull-Up resistors. I think that probably some of you already used this Arduino feature (It’s actually on all ATmega 328 microcontroller) but never realized what It was.
