While building robotics projects, the importance of controllers and motors cannot be overstated. These components are the heart and soul of any robotic system, providing the necessary control and ...

You may have never used Raspberry Pi or Arduino, but chances are you’ve heard of them. Raspberry Pi has been the bestselling British computer for years now, and Arduino has been transforming the DIY ...

Despite their similar sizes and affordable prices, microcontrollers and single-board computers have vastly different specifications and use cases. After all, MCUs are designed for circuitry, ...

The Raspberry Pi Pico is a low-cost, high-performance microcontroller board, It has flexible digital interfaces and it is very small but powerful. The board offers users the chance to develop projects ...

Over the last decade, the open-source movement has not only transformed the world of software, but also catalyzed a sweeping revolution in hardware tinkering. At the heart of this shift lies a ...

The worst thing about a volume knob is that, having connected it to a computer, it might be wrong: if you’ve manually altered the volume settings somewhere else, the knob’s reading won’t be correct.

Permanent magnet dc motors need a chunky inductor in series with them if they are fed from an SCR (thyristor) based mains power controller. It is (probably!) possible to safely interface an Arduino to ...

Most DIY tech enthusiasts have heard of a Raspberry Pi. But, like all things in the tech world, competition is inevitable. Arduino is a microcontroller used to control motors, LEDs, and interfacing ...

Read part 1 of this series on construction and operating principles here. Having understood the construction and basic operating principle of BLDC motor in the first part of this article, it becomes ...
