RGB Backlight for LCD

[inversesandwich]

Would it be possible for the Gamebuino to have a tri-color LED backlight for the LCD instead of plain old white. You could make it display all the colors of the rainbow and more! It would be pretty cool if it pulsed red when you lost a life, and green if you collected an item, for example.

Yes its possible but you have to switch the 4 LEDs from the LCD and you need 3 free ports from the Atmega32 to generate a PWM for each color led (RGB)

yes, but you can use an i2c rgb led like this:

uu can probably hack one in with sacrificing a expansion port, i say hack since u need to desolder the screen to place them then again may as well have a hole new lcd like this one http://www.adafruit.com/products/250
but this is probably as big has the hole gamebuino

RGB LEDs wouldn't fit directly under the screen and the atmega is out of pins... but I plan to include RGB LEDs in the expansion module to change the whole Gamebuino's color

[adekto]

tiny leds will fit under there
i got these tiny leds only in white though but those can fit under there (this is for a hack not expansion sinc eu still need the desolder the screen to glue them to the pcb)
