I'm controlling the values of an RGB LED with byte values from processing, but once the Red LED turns on it won't turn off again, even though the if/else statement should be setting the redLEDPin to 0 when the byte value is >127
Here's my code!
const int greenLEDPin = 9;
const int redLEDPin = 11;
const int blueLEDPin = 10;
void setup() {
// put your setup code here, to run once:
// initialize the serial communication:
Serial.begin(9600);
// initialize the 3 lEDPins as outputs:
pinMode(greenLEDPin,OUTPUT);
pinMode(redLEDPin,OUTPUT);
pinMode(blueLEDPin,OUTPUT);
}
void loop() {
byte tweetValue;
// check if data has been sent from the computer:
if (Serial.available()) {
// read the most recent byte (which will be from 0 to 255):
tweetValue = Serial.read();
// set the brightness of the LED:
if (tweetValue<127){
analogWrite(redLEDPin, map(tweetValue, 0, 126, 255, 0));//maps a negative tweet value to the red LED
analogWrite(blueLEDPin, 0);
analogWrite(greenLEDPin, 255);}
else{
(analogWrite(blueLEDPin, map(tweetValue, 127, 255, 0, 255)));//maps a positive tweet value to the blue LED
(redLEDPin, 0);
analogWrite(greenLEDPin, 255);}
}}
