WebbLets say just for your first LED we will fade from blue to purple over 3 seconds, we need to slowly increment the values of RGB the values of purple. Blue = (66, 101, 244) - Starting colour . Purple = (143, 65, 244) - Target colour . So we need to increase Red from 66 to 143, Green from 101 to 65, and Blue from 244 to 244 over 3 seconds. Webb20 feb. 2013 · As you change the duty cycle of the pin, the eye acts like a filter and perceives a shorter on time as a dimming in brightness. 1 - Use a PWM pin output instead of a digital GPIO pins. By changing a few registers you can change the on time of the LED and thus the brightness. 2 - Use a timer (polled or interrupt) to change the state of your pin.
