Wireless power, no matter how inefficient it may be, sounds good and even looks good with the “5V remote wireless power supply LED pack” we feature in this post. It also feels magical with the LEDs ...

Adafruit has recently released the Adafruit Sparkle Motion Stick, a compact, WLED-friendly Neopixel USB controller board built around an ESP32-S3 Module designed for audio-reactive LED projects, ...

This is a very simple LED dimmer circuit which has 2 transistors, 1 resistor and 2 potentiometers. Typical segment displays LEDs consume around 25 mA for each segment and should be limited to this ...

The project is built inside a box, which is then locked by an electro-magnet. To unlock the box someone has to bring the box to three different programmable GPS - locations (order is not important).

Software is based on HomeSpan library. Supports RGB or RGBW Neopixel strips and optionally can act like a switch for any 5V electronics (Switch accessory in HomeKit can be shown as a Bulb, Socket or ...

I've been trying to use some led's on a glowpad and have found that I keep getting different intensities on the same led depending on it's power source. When testing, I've been using a 6 volt wall ...

If you’re looking to control WS2812 (or Neopixel) LEDs using a microcontroller running at 3.3 volts, you might run into some issues. The datasheet tells us that a logic high input will be detected at ...
