Rgb dimmers are most of the time dimming according figure 1. It’s simple code, just increase al the colors 1 step a time,\u00a0 but the disadvange is that blue is ready first and red the last and that looks not that realistic. It would be neater when all 3 colors will start and finishing together as seen in figure 2.
\nThis code will fade all colors together.
\nTimer3 is used to controle the 3 pwm channels.
\nTimer0 is the delay for the steps. It’s with this xtal and preload an delay of 20ms. If you are going to use a other crystal then you need recalculate the timer0 preload.<\/p>\n
