Hi there,

Using the DFRobot LCD-keypad with the project, how did you manage to use pin 10 and 11?

Thanks

On the DFRobot LCD-Keypad schematic, I just noticed that the pinouts are VCC, 1, 2, 3, 11, 12 and 13.

Using a duemilanove, it leaves only the pins 3 and 11 for the PWM. I should use a shift register such as the 74HC595 to expand for more lights.

They say RTFM… >_<
