How to power Arduino with VIN?

Here’s the short, safe guide to powering an Arduino via VIN. 1) What VIN is (and isn’t) VIN feeds the board’s 5 V linear regulator. Use it when your source is \> 6 V and < ~20 V. Recommended: 7–12 V (sweet spot: 7–9 V to reduce heat). Do NOT put 5...

What is the Arduino Uno duty cycle?

This is an excellent question that gets to the heart of how Arduino controls things like LED brightness, motor speed, and servos. The short answer is: The Arduino Uno itself doesn't have a fixed duty cycle. You, as the programmer, define the duty cyc...
