ADCTouch with midi

Projects Programming
1

I kinda new, but some what expriance with arduino, but ive been trying to make a midi controller, got most of the stuff done but just one thing i need help on is that i want to implement ACDTouch to my project like when i touch the plater it send a midi command but dont know how to, if anyone can help out will be great

heres the script im using

#include <MIDI.h>
#include <RotaryEncoder.h>
#include <ADCTouch.h>

RotaryEncoder encoder(18, 19); //Encoders are connected to pins 18-19 and 2-3 (A and B of each encoder)0
RotaryEncoder encoder1(2, 3);



MIDI_CREATE_DEFAULT_INSTANCE();
int ref0, ref1;     //reference values to remove offset

int buttonApin = 12;  //footswitch A
int buttonBpin = 11;   //footswitch B
int buttonCpin = 10;   //footswitch C
int buttonDpin = 9;
int buttonEpin = 8;

int analogpot1 = A3;  //knob 1

int analogpot1Old = 0;
int analogpot1New = 0;


#define analogpot1CC 54

void setup() {
  // put your setup code here, to run once:
MIDI.begin (); // MIDI START

ref0 = ADCTouch.read(A0, 500);    //create reference values to 
ref1 = ADCTouch.read(A1, 500);

pinMode(buttonApin, INPUT_PULLUP);
pinMode(buttonBpin, INPUT_PULLUP);
pinMode(buttonCpin, INPUT_PULLUP);
pinMode(buttonDpin, INPUT_PULLUP);
pinMode(buttonEpin, INPUT_PULLUP);

pinMode(analogpot1, INPUT);

//Serial.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly:

    if (buttonAvalueNew != buttonAvalueOld){
      if (buttonAvalueNew == LOW){
      MIDI.sendNoteOn(60, 127, 1);
      //Serial.println("Note C On");
      }
      else {

    } else if (pos > newPos) {

It looks like you already copied most of the "Buttons" example that came with the ADCTouch library. You just need the part that tests the buttons:

    int value0 = ADCTouch.read(A0);   //no second parameter
    value0 -= ref0;       //remove offset
    Serial.print(value0 > 40);    //send (boolean) pressed or not pressed

Those three lines per pin can be reduced to one line per pin:

    if ((ADCTouch.read(A0) - ref0) > 40)
    {
      // Pin A0 is being touched
    }

    if ((ADCTouch.read(A1) - ref1) > 40)
    {
      // Pin A1 is being touched
    }

I got that part but how to i make that to work with midi?

The same way that you make a button work with midi.
