Reusing the LM4041 voltage regulator to create a precision current source by leveraging the CATHODE pin as a sense pin.

If you’re breathing in nasty VOCs or dust, surely a little blinking LED isn’t enough to express your displeasure with the current situation. Luckily, [Tobias Stanzel] has created the AqMood to ...

The Hackaday crew acquitted themselves well, and though an 01005 resistor and LED certainly pushes a writer’s soldering skills to the limit it’s very satisfying to see it working. Lest that ...

This project demonstrates how to blink an LED on and off using an Arduino UNO. It is a beginner-friendly project to get started with Arduino programming, basic electronics, and controlling outputs ...
