MCUs are ideal MQTT clients because the protocol is lightweight and designed for low-bandwidth, low-RAM environments.

An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention. The “automatic toll gate system project” demonstrates how simple sensors and ...

For some, Halloween is starting to rival Christmas for setting up elaborate holiday decorations. Homeowners now spend many hours─and sometimes dollars─creating ghoulish displays of lit pumpkins, ...

America’s overreliance on GPS leaves it vulnerable to jamming and spoofing. Building a terrestrial backup using 5G could secure national defense and critical infrastructure. The Global Position System ...

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm Cortex-M4F microcontroller, but offered in a much more compact form factor. It’s ...

In the previous video in this series, I built a robot arm for the robot using Dynamixel Servos at each Axis. The inverse-kinematic model runs on a Teensy Microcontroller, and now it's time to ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...

This library connects PC clients and Unity game engine instances to custom hardware modules controlled by Arduino or Teensy microcontrollers. It is designed to work in tandem with the companion ...

Arduino libraries, like libraries for other programming languages, help easily extend the range of functions available to users in the standard integrated development environment (IDE). They are ...
