The Arduino Uno board has over 20 pins that you can use for many different applications. In this post I’ll give you a complete and practical overview of the main Arduino Uno pins.
If you’re starting with Arduino, or if you’re already a software developer and want to learn more about the bridge between software and hardware on an Arduino board, then you’ve come to the right place!
In this post you’ll see :
- What are the pins you can use
- What you can do with them
- And some tips on how to connect other devices to your Arduino pins
I’ll also give you some examples of sensors/actuators that you can use with each pin functionality.
