    Ok. So im an engineering student getting used to arduino and picked up this shield.to play with. After an hour i got it to display 8 lines of random generated data. Next I used that code to update an existing program which controles a dc motor and propeller to achieve some desired life using a pid… Silly me though I forgot to check and see if a pin is being shared or not, one was and as a result my uno is messing up calling an avdr error, i believe that my serial port is fried though I could be wrong. So i fixed the code and tried it on my mega and it worked fine for a few hours of use. Then I got random characters showing and now the lcd is not showing anything at all, after just 4 hours of use. My question is what could cause it to fail? Also i soddered pins 2,3,4,5,8,9,10,11,12,13,gnd(top right),the teo gnds on the left, and the 5 and 3.3 volt pins. Is this excesive or nessicary. It looked like the schematic called that these are used.

No public wish lists :(
