Build your own ESP32 and ESP8266 projects this weekend. We detail 10 practical IoT builds, including a Wi-Fi weather station using a DHT22.

DigiKey and Arduino will award four contestants with a custom, dream-lab package valued at approximately $5,000 each. The lab ...

Program $20 ESP32 microcontroller boards using Claude Code to build Bluetooth audio spectrum analyzers and sea displays without reading a manual.

GUEST OPINION: Choosing a suitable microcontroller is a crucial stage of any electronic system creation. MCU works as the brain of an application, managing the communication between components and ...

A lot of microcontroller projects out there need some sense of wall-clock time. Whether you’re making (yet another) crazy clock, logging data, or just counting down the time left for your tea to steep ...

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 ...

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 ...

This project describes the design of a 7-segment LED-based counter which counts from 0 to 9 continuously with a one-second delay between counts. The project shows how a 7-segment LED can be interfaced ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...
