Light my LCD
It is not a good sign when I look things over and over again and again and don’t find any bugs. Not that I have trouble to keep the few things in my head, no, now I really suffer from concentration deficits and that is a big indicator for an overdue holiday. Why you ask? I ordered a new Roboduino from China. I couldn’t track any bug and logical solution seemed to order a new one to sort out potential failures on the board.
My inital test with the mutli-color LED failed right away and so I gave it a shot with LCD. Heureka! The LCD works as it is supposed to, showing a “hello world!” and counting the seconds. Mhhh… so why does the LED still not work. Maybe I am too blind to see. So I put the LCD back to the old roboduino and voila, it works too. It looks like I mixed cables or something… anyway, I found a nice little example of how to create custom charactrers on the LCD and made pixeled the Omnibotlogo. Here’s the link to the tutorial.
LCD check: go… LED check: no go… too stupid to wire three four cables in the right order. I really need some days off…
