PWM Backlight Workaround for LCD Backpack. Dan writes –

I really like the Adafruit LCD Backpack, but I’ve been wanting to play around with adjusting the LCD backlight brightness programatically.  After much mulling and reading of forum posts, I decided to just operate the backlight using one extra wire to a PWM pin on the Arduino.  To try and keep things tidy, I ordered some extra 3-pin terminal blocks so I could make a 6-pin block instead of the normal 5-pin block.  Just to up the stakes, I’m doing this with my brand new 20×4 LCD.
