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.

Enter the ExtraCore library for Arduino, a software library that turns two or more Arduinos into a multi-core microcontroller with more pins than you’ll ever need. The ExtraCore library comes ...

The ESP’s extremely flexible hardware peripheral routing matrix allows it to assign the SPI functions to any pins, but the Arduino implementation ... you write that the macro MSBFIRST isn ...
