PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

It is important that you know at least the basic difference between PinInterrupts and PinChangeInterrupts.I will explain the basics of PinChangeInterrupts (PCINTs) based on an Arduino Uno.. On a ...

The Arduino UNO has 14 digital I/O pins and 6 Analog inputs. The digital I/O pins are 5V logic level and you can also use the Analog pins as digital I/O too. Arduino UNO supports 6 channel 10 bit ADC ...

Both the Arduino Nano and Uno can be powered via their integrated USB connectors. This automatically supplies regulated 5V power to the board, allowing you to use any USB-supported power source ...
