Hi guys.
I'm new to this Arduino thing. I have a uni project that I am working on which is to control arduino robot from PC through USB. I am trying to control the robot with the software Scratch 4 Arduino(S4A).
My hardware setup currently is just arduino UNO with an arduino 2A motor shield (L298) connected to tamiya gearbox which holds 2 DC motors all bought from Cytron. What I am having now is I can play around with the values on pin 5 and 6 and it worked well (ie speed changes). However, I not able to change the direction of the motor (pin 4 and 7)even though I tried changing it in S4A. Both motors spin counterclockwise which make the robot spin one direction forever. Is there something wrong with my S4A sketch (ie. anything I should add/drop)? Can someone out here whose familiar with S4A help me? Or maybe offer other wired-solution than using S4A? right now wireless is not an option for me.
Thanks
Yasir
