to Arduino pins 0 and 1. The APC220 module (see next image) has a total of nine pins (only seven are in use), and its small size makes it an ideal solution for wireless data transfer applications.

Arduino has introduced a new feature to its Arduino Cloud platform: the Image widget. This addition aims to improve the user experience by allowing for greater customization and visual appeal in ...

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.

Source a nice and noisy germanium diode, give it a couple of op-amps to amplify and filter the noise before feeding it to that Arduino pin. Maybe you were thinking about radioactive decay and ...

Apart from understanding the Arduino's code language, one of the most confusing parts about the platform — especially for beginners — is picking the right board to use in a project. Sure, it ...

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 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 ...

Except, on the Micro, there is no actual serial bus involved in programming the Arduino, as everything is done over USB. So the TX and RX leds are driven by a couple of pins on the ATmega32U4 (see a ...

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 ...
