the above is the code for the rgb code this is how i implemented the teal orange and white color modes. the colors changes after pressing a button. The orange and Teal color blinks automatically though.

the output on the serial port says ther's nothing to be found so i believe it i htink its the wiring, or a stupid mistake in the code

//Simple Motor Speed Control Program const int MOTOR=9; //Motor on Digital Pin 9 void setup() { pinMode (MOTOR, OUTPUT); } void loop() { for (int i=0; i<256; i++) { analogWrite(MOTOR, i); delay(10); } delay(2000); for (int i=255; i>=0; i--) { analogWrite(MOTOR, i); delay(10); } delay(2000); } i got the code to make the motor run , but the potentiometer didn't change the speed of the motor, but as a on and off switch. i strongly think its because i didn't wire it correctly.
