From Scratch to Arduino Test Bed
In my last blog entry, I created a new graphical interface in Scratch for transmitting data to the microcontroller on the robot. Tonight I verified that the Scratch program is able to communicate via screen flashes with the Arduino test … Continue reading
Grisbot screen interface for light track
You know, time just flies when I’m doing graphic design. I sure wish I was good at it. Anyhow, the above screen shows the graphical interface (in Scratch) for programming the robot in ‘light track’ mode. 0a: Specifies the distance … Continue reading
