LED light strips with ultrasonic brightness controls.

• Two independent LED strips
• Brightness controls via ultrasonic sensors

Requires assembled hardware (see below) and PlatformIO.

1. Adjust ports in platformio.ini
2. Adjust pins, number of LED pixels and color settings depending on your needs in src/main.cpp.
3. Flash device

Required libraries:

• Adafruit NeoPixel
• Bifrost library for HC-SR04
• Low-Power

See (development section above)[#Development].

• Arduino Nano v3/Mini/Uno/...
• 2× 100µF capacitors
• 2× NeoPixel LED strips with 12 pixels (WS2812B)
• USB Micro Plug
• Wires
• Plastic case
• USB cable (USB A to micro)
• Power supply (>= 2.5A, depends on the number of pixels of your LED strips)
