Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

A low pulse on this pin (below 1/3 of VCC) sets the internal flip-flop and makes the output go HIGH. When the voltage on this pin reaches 2/3 of VCC, it resets the flip-flop, and the output goes LOW.

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

Making a servo tester using an Attiny85 micro chip, Attiny45 also works for this project. This diy servo tester is as good as any other servo tester, the difference is that it can be programmed to do ...

I've completely swapped my home over to LED lights, and for the most part, I love it. The energy savings are real, and I'm a sucker for all the smart color changing tes. But my biggest grievance is ...

A reboot of the classic disaster film has caused a surge in amateur storm chasing. So what is it really like to chase tornadoes? Professional storm chasers monitor a tornado in Kansas, where tornadoes ...

NPR's A Martinez speaks with journalist Mark Medley about his new book, "Live to see the Day," an exploration of people motivated by nearly impossible goals.

This library currently supports any board based on the ATmega168, ATmega328P, ATmega32U4, or ATmega2560 which runs at 8 MHz, 16 MHz, or 20 MHz. The LED strip's input connector has two pins that should ...

This repository contains support for the following SparkFun Arduino-compatible development boards. IMPORTANT NOTE: These board files have been updated for compatibility with Arduino version 1.8 and ...
