Arduino doesn’t have the cultural cachet of its fellow single-board player Raspberry Pi, but it’s arguably more popular for ...

The table shows the pin configuration of the Arduino UNO–based robotic arm. The red (VCC) wires of all servos are connected to the breadboard positive rail, and the brown/black (GND) wires are ...

If you have a home lab, you probably think first about servers, networking gear, and SBCs. Those are all great tools, but they live mostly in the digital world. A basic Arduino board, like the Uno or ...

Arduino is a microcontroller designed for real-time hardware control with very low power use. Raspberry Pi is a full computer that runs operating systems and handles complex tasks. Arduino excels at ...

The big picture: If you don't know anything about electronics but have always wanted to learn and build your own IoT project, Arduino has the solution for you. The Plug and Make Kit is a comprehensive ...

With these mods, this circuit will last quite a long time, especially if you make things easier for the relay by turning off power to the motor before switching directions. It is simple and effective ...

Sure, you can buy a cable tester, but what fun is that? [Ashish] posted a nice looking cable tester that you can build with or without an onboard Arduino. If you don’t use an Arduino, the project uses ...

The Arduino Opta micro programmable logic controller (PLC) provides a unique entry point into the automation field. Automation fields like smart homes, process controls, and robotics are project areas ...

There are many ways to detect a heartbeat electronically. One of the simpler ways is to take [Orlando’s] approach. He’s built a finger-mounted pulse detector using a few simple components and an ...

Usually, I use the Serial Monitor of the Arduino IDE to communicate with the Arduino hardware. But now, I want to build an application on my computer that allows me to click some buttons to control ...
