capacitive sensor

[salahjardali]

Hi

Iam using the capacitive sensor with Neopixel. When i upload the code, the program give me an error regarding the RGBpixel. Here is the code

Code: Select all

#include <CapacitiveSensor.h>
#include "Adafruit_NeoPixel.h"


/*
 * CapitiveSense Library Demo Sketch
 * Paul Badger 2008
 * Uses a high value resistor e.g. 10M between send pin and receive pin
 * Resistor effects sensitivity, experiment with values, 50K - 50M. Larger resistor values yield larger sensor values.
 * Receive pin is the sensor pin - try different amounts of foil/metal on this pin
 * Modified by Becky Stern 2013 to change the color of one RGB Neo Pixel based on touch input
 */


CapacitiveSensor   cs_9_10 = CapacitiveSensor(9,10);        // 10M resistor between pins 4 & 2, pin 2 is sensor pin, add a wire and or foil if desired
//CapacitiveSensor   cs_9_2 = CapacitiveSensor(9,2);        // 10M resistor between pins 4 & 6, pin 6 is sensor pin, add a wire and or foil
//CapacitiveSensor   cs_4_8 = CapacitiveSensor(4,8);        // 10M resistor between pins 4 & 8, pin 8 is sensor pin, add a wire and or foil
Adafruit_NeoPixel strip = Adafruit_NeoPixel(1);

void setup()                    
{
   cs_9_10.set_CS_AutocaL_Millis(0xFFFFFFFF);     // turn off autocalibrate on channel 1 - just as an example
   Serial.begin(9600);
    strip.begin();
    strip.show();

}

void loop()                    
{
    long start = millis();
    long total1 =  cs_9_10.capacitiveSensor(30);
    //long total2 =  cs_9_2.capacitiveSensor(30);
    //long total3 =  cs_4_8.capacitiveSensor(30);

if (total1 > 75){
  digitalWrite(7, HIGH);
  strip.setPixelColor(0, Color(0,255,0));  
  strip.show();
} else {
  strip.setPixelColor(0, Color(0,0,0)); 
  strip.show();
}
  
    Serial.print(millis() - start);        // check on performance in milliseconds
    Serial.print("\t");                    // tab character for debug windown spacing

    Serial.println(total1);                  // print sensor output 1

    //Serial.print("\t");
    //Serial.println(total3);                // print sensor output 3

    delay(10);                             // arbitrary delay to limit data to serial port 
}

// Create a 24 bit color value from R,G,B
RGBPixel Color(byte r, byte g, byte b)
{
  RGBPixel p;
  
  p.red = r;
  p.green = g;
  p.blue = b;
  
  return p;

the program give me an error regarding the RGBpixel. Here is the code

It would help if you posted the error code too.

From the looks of it, you are missing the closeing '}' bracket on your Color function. And I don't see anywhere that you are defining the RGBPixel type.

Hi now there is no error, but the neo pixel is not lighting when i touch the fabric. Only the LED 7 is lighting. and this is my code:

Code: Select all

#include <CapacitiveSensor.h>
#include "Adafruit_FloraPixel.h"


/*
 * CapitiveSense Library Demo Sketch
 * Paul Badger 2008
 * Uses a high value resistor e.g. 10M between send pin and receive pin
 * Resistor effects sensitivity, experiment with values, 50K - 50M. Larger resistor values yield larger sensor values.
 * Receive pin is the sensor pin - try different amounts of foil/metal on this pin
