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 Arduino Nano and Raspberry Pi Pico have distinct pin configurations ... Any time you find a function or structure element confusing, you can consult the documentation. Conveniently, the ...

Here, the three LEDs are directly connected to Arduino pins with independent current limiting resistors (R1, R2 and R3) which is enough for a basic model. But if you wish to control Hi-Power LEDs (or ...

This circuit can be considered as a general purpose daisy-chained parallel shift-out register group for a total of 32 output ports that we can easily manage with our Arduino board (or similar ...

One unusual thing about the keyboard is that it is not multiplexed. Each button has a label that indicates what Arduino pin it connects with. So key 6 connects to pin 6 and pin A2 connects to the ...

The outputs from the potentiometers are analog, so they can have a value only between 0 and 1,023 when read by the analog pin of the Arduino. This number sends a pulse to the Arduino, which in ...

It transpires that folk have been busy writing ‘cores’ – the name for code that adapts Arduino code to run on different hardware – for several other bare chips, and some have 20 pins – plenty. Have ...

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 ...
