Lilypad RGB led pwm help
Hi everyone, I have started working with my new Lilypad Arduino and some RGB leds. I have been loading code and testing 4 RGB leds (common anode) which I have set up in parallel across pins 11, 10, and 9. While powering the lilypad by usb the leds cycle through all colours (which is what I programmed it to do). Unfortunately, I have a problem when powering the lilypad by this power supply
When powered by the power supply the only colour that lights up is red (pin 11). Can anyone suggest anything?
