Hi.
I am trying to control the colour of my Neopixel strip with 3 potentiometers. I thought I could read the value of each potentiometer, change the scale down to 0 - 255 from 0 - 1024 which is the potentiometer scale.
Then input these three numbers into the colour of the pixels, each potentiometer being used for R G or B.
What happens is only one potentiometer actually affects the neopixels and that's the first pot.
Here's my code, I was thinking that you can have a maximum of 1 potentiometer but that's all I can think of??
#include <Adafruit_NeoPixel.h>
#define PIN 9
Adafruit_NeoPixel strip = Adafruit_NeoPixel(60, PIN, NEO_GRB + NEO_KHZ800);
int sensorValue = analogRead(A0);
int sensorValue2 = analogRead(A1);
int sensorValue3 = analogRead(A2);
int currentColourValue;
int currentColourValue2;
int currentColourValue3;
void setup() {
strip.begin();
strip.show(); // Initialize all pixels to 'off'
}
void loop() {
currentColourValue = (255 - map( analogRead(sensorValue), 0, 1024, 0, 255 ) );
currentColourValue2 = (255 - map( analogRead(sensorValue2), 0, 1024, 0, 255 ) );
currentColourValue3 = (255 - map( analogRead(sensorValue3), 0, 1024, 0, 255 ) );
colorWipe(strip.Color(currentColourValue, currentColourValue2, currentColourValue3), 50); // Red
}
void colorWipe(uint32_t c, uint8_t wait) {
for(uint16_t i=0; i<strip.numPixels(); i++) {
strip.setPixelColor(i, c);
strip.show();
delay(10);
}
}
