[Resolved] Arduino Robot - Control board white screen and disconnecting com port


Please help me troubleshoot my Arduino robot.

Symptom :

  • When powering on only a blank white screen is displayed.
  • I Can hear the com port connect and see it registering on com port 10 as Robot Control board then is just immediately disconnects

I have tried the reset buttom on control board and motor board

8) Any assistance will be greatly appreciated. Please and thank you

Those are the com ports i have.

Robot Control board: If i plug into the top controller board it disconnects after 2 to 4 seconds. :~
Robot Motor board: COM8 comes up and i am able to upload the Motor_Core sketch

I am investigating the boot-loader area of this robot. Am i going in the wrong direction?

  • Downloaded IDE 1.0.5-r2 for Windows http://arduino.cc/en/Main/Software

  • Uninstalled Arduino IDE via control panel

  • Deleted C:\Users\cs\Documents\Arduino\libraries folder

  • Deleted the whole folder C:\Program Files (x86)\Arduino

  • Installed IDE 1.0.5-r2 for Windows and selected correct serial port and board

I struggled for a good few weeks with this issue. XD

The root cause was the incorrect placement of library files and running on older versions of Arduino IDE.
