Features
- 3U 6HP Eurorack card
- Arduino Pro Mini CPU
- 16 MHz
- 5V
- Drives recessed NeoPixel strip in top of Eurorack box
- Daughtercard to ER-PROTO-02 card
- Uses Front Panel and Controls card
- RV1 = Mode knob
- 4 modes: 3 rainbow, 1 white
- RV2 = brightness
- GATE input could be used to step between rainbow pattern
- LED strip types (Ebay search)
- Using 30 LEDs per 1 M
- Other options are 60 LEDs/M or 144 LEDs/M
- 16 pin (8x2) box power connector
- Requires 5V at current depending on the number of LEDs
- From Powering NeoPixels Adafruit page
- Each individual NeoPixel draws up to 60 milliamps at maximum brightness white (red + green + blue)
- 17 LEDs (30 LEDs/M) in 104 HP rack = 1A
Arduino Pro Mini
Software
ER_LEDS.ino - Software Build
- RV1 - Pattern
- White
- Color
- RV2 - Brightness
Build
- 1000 uF cap on 5V power
- RV1, RV2 jumpers on controls card for Vcc/GND
- Vcc is 5V from daughtercard
- Series resistor on Data Output line
- GVS (Ground, Vcc, NeoPixel data line) on 1x3 header
- Arduino uses +12V into "RAW" pin of Arduino Pro Mini
