The Arduino Mega's PWM pins are digital output pins located on D2 to D13 and D44 to D46, coming to a total of 15. While they function as normal digital pins that can switch a component either ...

Or perhaps you could buy something like an Arduino Mega, with its extra sockets to fulfil your needs. But what would you do if you really needed more pins ... channels via an I2C interface.

One of those hard limits, even for the Arduino MEGA, is a finite number of pins ... All that is needed is to connect the I2C pins of the microcontrollers and provide each with power.

It can be very helpful when you want to measure the outside, inside or other temperatures in the same time but you don’t want to use a lot of pins of your Arduino board. I2C protocol makes it easier ...

Adafruit has this week announced the arrival of the new Arduino ... pins hooked up to one microcontroller. Adafruit explains a little more about the new breakout board. You just found the perfect ...

The Uno also has a limited number of pins, making it difficult to work with when the project requires plenty of input and output components. However, these two areas are where the Arduino Mega shines.
