Once you get the communication going , time to upload the first sketch .
It's all very wel document in the book .
Hell yeah , I managed to make a led blink
, I'm a programmer now .WOW
Wel not in the least , but it sure felt that way
Then i installed the button shield , and tested it with a few sample sketches that drive the lcd and test the buttons .
Google for lcd button shield , see if you can identify your shield and download the test software for it . I found at least 3 different versions , you'll have to identify yours on sight .
So I eagerly plugged in the shield , uploaded the test sketch - hey I'm a programmer remember - and once again .... nothing happend .
The backlight goes on with a beautiful blue glow , so that's ok . But no text , no reaction to the buttons being pressed .
Damn , the "programmer " in me suddenly got a lot smaller .
Until I noticed a small trim potentiometer on the upper left corner of the shield . This is the contrast adjustement .
Yep that does it , turned it up and the letters start to appear .
Silly isn't it , but for a total noob ....
That 's it for now , to be continued .
