Thanks I will give it a look once I’m done I will post pics of device!
Actually, in your programming Arduino IDE, select File-> Examples -> digital write (a.k.a, PWM), 1602 display and several others are already on your computer - just cut, paste, edit, experiment, show it to your friends. Be the envy of the neighborhood.

Personally, I like the I2C 4x20 LCDs because they only tie up two pins.

I suppose you ride a three wheeled "motorcycle" as well.
He obviously rides a two wheeled one, where you ride a 14 wheel one :D

As he says, it makes life a LOT easier if you use the I2C interface chip, it's really just a question of the trade off between an extra chip and I/O lines.
