Issue with the electronic brick starter kit

Hello dear seeedstudio crew,

I am having a contrast problem with the lcd 1602 contrast from the electronic brick starter kit set

I already posted my problem on the arduino forum as seen here:,69656.0.html

so how do I change the contrast on my lcd? Is my lcd probably broken?

Regards, Soelen

The code on the pdf tutorial is right now not working anymore with the current release of the arduino ide! An begin() method have to be inserted to let the display work! You guys have to update your pdf tutorial for comming arduino hobby developers!

Big thanks to Don for explaining the behviour!
