Years ago the Arduino plattform was published to the market. I already know something about microcontrollers at this moment. In school we made some first practises with programming a microcontroller (I think it was an Atmel..). The
beginning was not easy. At first I had problems to understand the programming language C. I don't try so much. With switching some LEDs on and off or react to key press was the best I done in this time. Secondarily I had school and my
apprenticeship that need much time. Further I see some other interesting projects where I can't signify how to do something like that.
After I got some more experience with microcontrollers of my school, I tried something more with it. An impact to this had an experiment of classmates that tried to programm a mini robot to move with sensor controlling. I also want to do
something like this and saw that the Arduino plattform have a "robot".
I tried to let the robot move. But I don't understand the thing that the examples work every time but when I do my own calls to the robot API it does not. I didn't get the robot to move while the examples of the robot worked.
The robot is build of two PCB panels stacked over one another. The electronic parts are soldered on, so on the bottom side there are spiky soldering joints. To protect them agianst the groud there is a covering, but it is made of paper. And
when the robot moves the cover askews and gets damaged. Further it not possible to let the robot move on a carpet while there are the soldering joints. But this is a needed thing.
Then I tried write something to the display. Also here the exampels had worked. But when I tried to write out some lines to the display, it doesn't worked. I first tried to remove the old line and then write the new inplace. But this was
not happening. But the overwriting worked like it only stores more and more black points over existing points. This makes me a bit disappointed.
But a time later there were other projects. For private and for school. You can find some of them here in subpages.
