[Jacob Geigle] had a problem. A GPS unit and a Bluetooth-to-serial were tying up all the hardware UARTs on an AVR Arduino project. “Software serial”, I hear you say. But what if I told you [Jacob] ...

libmodbus is a library that provides a Serial Modbus implementation for Arduino. A primary goal was to enable industrial communication for the Arduino in order to link it to industrial devices such as ...

The SPI protocol is a "standard" for serial communication, however there exists many variants. This document only describe the four modi typical used in the Arduino context. The SWSPI library ...

[Andrew] wonders why the SerialUSB() function on the Cortex M3-based Arduino Due is so much faster than Serial() on the Uno or Nano, and shares his observations in this short video. He sets up an ...

Before opening the Arduino software, wire up the Arduino according to the circuits page using the 8MHz minimalist breadboard circuit but with a 10k pull-up resistor on the reset pin (physical pin 1).

Fascinated with electronic projects and want to build your own? Arduino boards can most definitely help with that. These microcontroller boards are designed to send and receive data to and from the ...

Celebrate 20 years of Arduino software and tools with a spotlight aimed at industrial automation, AI, rapid prototyping and more. Since it began in 2014, Arduino Day has been an annual celebration of ...
