34+ Arduino Board Pins Explanation Pictures. Introduction to arduino uno board and all the components for beginners. In this post i'll give you a complete and practical overview of the main arduino uno pins.
Arduino (atmega) pins default to inputs, so they don't need to be explicitly declared as inputs with pinmode() when you're using them as inputs.
In this case, the following graph can be a good guide to compare all parameters for selecting the proper board in your project. Input and output pins of arduino board models are different in type and number. Arduino boards commonly use a limited number of processor types and architectures. The most common being the atmega range using the avr without it, you will not be able to set the correct pin output functions or configure serial ports.
