Last year we built a drone using ESP32 and our community loved it. Since then the project has evolved and the drone is now ...

HT16K33 Library for Arduino This is a quick and dirty library providing a relatively easy-to-use interface for driving the Holtek HT16K33 16×8 LED driver IC. I wrote it for a project I was working on, ...

An Arduino library for 7-segment display modules based on the TM1637 chip, such as Seeed Studio's Grove 4 digit display. The TM1637 chip also has keyboard input capability, but it's not implemented in ...

AD3 is a sweet little box that can supply power (variable) to a circuit board or prototype. It has a built-in 125-MSPS ...

This is a very simple but useful project, strobe navigation lights for rc airplanes, or you can adjust the flashing time and make it a warning light for a forklift or even a turn signal light for ...

Single-phase ac light-emitting diode (LED) lamps require long-lifespan and high-efficiency ac-dc power converters for power factor correction (PFC) and current regulation. In such converters, the ...

A single-stage light-emitting diode (LED) driver has been developed integrating a single-ended primary-inductor converter with a half-bridge LLC resonant converter. The proposed topology reduces ...
