i have this, and i want to implement this into my code using one of the 'case' statements i have. now, i have no clue what i'm doing so help would be appreciated. i want to add it into the lowest one (play/pause key)
=]ppm #include <IRremote.h>
// Define sensor pin
const int RECV_PIN = 4;
// Define LED pin constants
const int redPin = 3;
const int greenPin = 5;
const int bluePin = 6;
// Define integer to remember toggle state
int togglestate = 0;
// Define IR Receiver and Results Objects
IRrecv irrecv(RECV_PIN);
decode_results results;
void setup(){
// Enable the IR Receiver
irrecv.enableIRIn();
// Set LED pins as Outputs
pinMode(redPin, OUTPUT);
pinMode(greenPin, OUTPUT);
pinMode(bluePin, OUTPUT);
}
void loop(){
if (irrecv.decode(&results)){
switch(results.value){
case 0xFF30CF: //1 key
// Toggle LED On or Off
if(togglestate==0){
digitalWrite(redPin, HIGH);
togglestate=1;
}
else {
digitalWrite(redPin, LOW);
togglestate=0;
}
break;
case 0xFF10EF: //4 key
// Toggle LED On or Off
if(togglestate==0){
digitalWrite(bluePin, HIGH);
togglestate=1;
}
else {
digitalWrite(bluePin, LOW);
togglestate=0;
}
break;
case 0xFF18E7: //2 key
// Toggle LED On or Off
if(togglestate==0){
digitalWrite(greenPin, HIGH);
togglestate=1;
}
else {
digitalWrite(greenPin, LOW);
togglestate=0;
}
break;
case 0xFFC23D: //play-pause key
if togglestate==0){
}
}
irrecv.resume();
}
}
Otherwise the LED doesn't ever hit a pure red output.
??? WHY ???
for (int decColour = 0; decColour < 3; decColour += 1) {
// When `decColour ==2`
int incColour = decColour == 2 ? 0 : decColour + 1;
// `incColour = 0` at this moment
After finish the i loop
,
rgbColour[0]=255;
and rgbColour[1]=rgbColour[2]=0; ... back to pure red
again...
right ?
Another kinds of colour cycle
it might ignore darker shade problem
but it's total different spectrum with original
void loop() {
unsigned int rgbColour[3];
// Start off with red.
rgbColour[0] = 255;
rgbColour[1] = 255; //// Different place !
rgbColour[2] = 0;
// Choose the colours to increment and decrement.
for (int decColour = 0; decColour < 3; decColour += 1) {
int incColour = (0==decColour ) ? 2 : decColour - 1; //// Different place !
// cross-fade the two colours.
for(int i = 0; i < 255; i += 1) {
rgbColour[decColour] -= 1;
rgbColour[incColour] += 1;
setColourRgb(rgbColour[0], rgbColour[1], rgbColour[2]);
delay(5);
}
}
}
for states :
255, 0, 0
255, 255, 0
0, 255, 0
0, 255, 255
0, 0, 255
255, 0, 255
255, 0, 0
void loop() {
unsigned int rgbColour[3];
// Start off with red.
rgbColour[0] = 255;
rgbColour[1] = 0;
rgbColour[2] = 0;
int decColour =0;
int incColour =1;
void loop() {
if (255<=rgbColour[incColour]) {
if (0>=rgbColour[decColour]) {
decColour++; decColour %= 3;
incColour++; incColour %= 3;
} else // if (0==rgbColour[decColour]) {
rgbColour[decColour] -= 15; // --
} else // if (255==rgbColour[incColour]) {
rgbColour[incColour] += 15; // ++
setColourRgb(rgbColour[0], rgbColour[1], rgbColour[2]);
delay(5);
}
}
You can also use the HSB model for your colors (if your mc is fast enough) then cycling through all colors will start to feel very natural. C++ for this can be found here https://github.com/rvt/Arilux_AL-LC0X
