A simple AVR microcontroller based circuit that can detect when you touch a metal probe connected to one of the mcu inputs. A simple AVR microcontroller based circuit that can detect when you touch a ...

The DTMF extension project is intended to detect DTMF tones and decodes them to binary digits that can be easily read by a microcontroller which can decide what jobs to perform. The DTMF extension ...

Judging from the video (found after the break) the Nebulophone is one of the best sounding DIY synthesizers we’ve seen. Especially when you consider the simplicity of the hardware design. It uses an ...

Meet the Raspberry Pi Pico 2 W, a tiny board designed around a microcontroller that lets you build hardware projects at scale. Raspberry Pi is once again using the RP2350, its own well-documented ...

[Aditya] had a project that called for spoken output. He admits that he could have built a PC-based solution, but he found that adding speech by using a microcontroller was not only a cheap and ...

Description: In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever ...

Snekboard is an open hardware development board that’s designed to let you hook up to LEGO Power Functions motors and switches so you can build robots out of LEGO and control them with CircuitPython ...

Costing a mere $4, the Raspberry Pi Pico was launched in 2021 using the in-house RP2040 chip. Unlike most other Raspberry Pi models, the Pi Pico isn't a microcomputer, as it is classified instead as a ...

An Arduino is one of the cheapest ways to built your own electronics prototypes and projects, but the Arduino Uno isn't exactly the most powerful device on the planet. If you're looking for something ...

Unijunction transistors (UJTs) were common circuit elements several decades ago. A simple ramp generator could be built from a single UJT and a few other components (Fig. 1). 1. In a simple UJT-based ...
