pd BioAmp Eurorack version
Made a nice case with 3mm mdf, laser-cut, glued and sanded to have rounded corners and sprayed nicely.
Materials:
- upside-dowb labs BioAmp EXG pill
- Seeed Xiao SAMD21 microprocessor
- 32x128 OLED screen (and pink foil)
- neo-pixel strip, 6 Leds
- 1 x stereo jack, 3.5mm
- 1 x 10kOhm potentiometer
- 1 x push-button
- 3 x mono jacks, 3.5mm
Arduino code
Based on the example codes by Upside Down Labs for reading and filtering the BioAmp EXG pill and the scrolling graph by Jon E. Froehlich.
Libraries:
- Wire (for i2c)
- Adafruit_SSD1306 (for the oled)
- Adafruit_NeoPixel
- Adafruit_GFX
Pd patch
How to receive data from Arduino through serial port in Pd (puredata)
- install "comport" extension. And then... first you will just receive the ascii-code number of the strings sent through the serial port. So we need to decode this.
Arduino_Pd

can be loaded from ./Arduino_Pd or copied directly into the patch.
cyclone extension
