Input and Output Each of the 14 digital pins on the Arduino Uno can be used as an input or output, using pinMode (), digitalWrite (), and digitalRead () functions. They operate at 5 volts. Each pin ...

Note: Some pins are not connected on a standard Arduino Uno R3 but still listed so you can use them if you had a custom board. It might also be possible that your ICSP header of the 16u2 is flipped ...

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.

The Board Overview Now, if we look at the Arduino Uno R4 WiFi development board, we can see that it comes with many hardware upgrades over its predecessor. Here is a part marking image of the Arduino ...
