I started to a build a RC car with spark core and had imagined to control the RC car with an android app developed from Appinventor. I was able to send basic commands from the app and it works fine. Later I found that it is not possible by appinventor to react to multitouch situations. For example if I want to accelerate and turn left at the same time, Appinventor can only react to one of the command.
I would really appreciate if you can give some ideas towards this .
