The ExtraCore library comes from [Dustin Andrews], and allows anyone to control the input and output pins of two Arduinos with the same ease as a single Arduino. The hardware setup is fairly ...

Often, when it comes to your Arduino project,you never have enough input/output (I/O ... In principle, Charlieplexing technique allows you to drive “n 2 −n” LEDs using only “n” Arduino pins. Here, we ...

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.

If you’ve ever tried to use a standard prototype board to mount on an Arduino, you’ll know what kind of person you are. When you notice the pins aren’t on 0.1 inch centers, you might think ...

and ATmega32U4 (Figure 10-2, Arduino Leonardo, Micro or Pro Micro) Arduinos have hysteresis built into the input side of digital IO pins (as does the ATtiny85 and ATtiny861A), and so can happily be ...

The Arduino Mega's PWM pins are digital output pins located on ... One is using an analog input like a potentiometer. In this case, the analogWrite() value is dependent on the value read from ...
