An RGB LED module is a versatile lighting component that can produce millions of colours by mixing red, green, and blue light. The RGB LED module used in this ESP32-S3 Box-3 Arduino programming ...

On Oct. 3, 1950, three Bell Labs scientists received a patent for a "three-electrode circuit element" that would usher in the transistor age and the era of modern computing.

After a major water leak flooded my home, I realized alerts alone weren’t sufficient—I needed automatic shutoff. This project combines a hacked Gröhe Guard system, an Arduino Nano, an ESP32, and the ...

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components to a 555. But you needn’t go so fancy! [The Design ...

Back in 1966, a suitable toy for a geeky kid was a radio kit. You could find simple crystal radio sets or some more advanced ...

To meet the growing demands of flexible and wearable electronic systems, such as smart watches and biomedical sensors, ...

A Planet Analog article, “2N3904: Why use a 60-year-old transistor?” by Bill Schweber, inspired some interest in this old transistor and how it’s commonly used, and if any uncommon uses might exist.

Frequent contributor Christopher Paul recently provided us with a painstakingly conservatively error-budget-analyzed Design Idea (DI) for a state-of-the-art pursuit of a 16-bit-perfection PWM DAC. The ...

Elektor DIY electronics projects don’t just invite readers to build — they spark innovation. Take the Mini Reflow Plate from ...

Qualcomm has made a move to acquire Arduino, which they will leverage for edge computing, robotics, and AI applications.

Qualcomm didn’t disclose what it would pay to acquire Arduino. The acquisition also needs to be approved by regulators “and ...
