Pitch control using VL6180X proximity sensor

My first DYI project with my AE modular system: controlling the pitch of GRAINS with Polyramp firmware using a VL6180X proximity sensor and an Arduino Nano




The code is very simple

#include <Wire.h>
#include "Adafruit_VL6180X.h"
Adafruit_VL6180X vl = Adafruit_VL6180X();

int output_pin = 9;

void setup() {
 vl.begin();
}

void loop() {
 uint8_t range = vl.readRange();
 uint8_t status = vl.readRangeStatus();

if (status != VL6180X_ERROR_NONE) {
   range = 180;
 }

 analogWrite(output_pin, 180 - range);
}


I have patched pin 9 of the Arduino Nano to IN1 of GRAINS. I noticed that 180 is the maximum range that my VL6180X is able to detect. There is some room for improvement. But for now I am quite happy with this quick&dirty approach.
