 *testcarcom.py* is a small Python application to test the Nexus_Omni4WD firmware (sketch). The python application sends data packages to set the wheel speeds.
 
 The Arduino controller 10009 with io expansion shield on the Omni4WD  is Duemilanove/ATMEGA328 compatible.

 **varDutyT1**
+
 A sketch for varying (modulating) the duty-cycle of the PWM on the UNO-output pins 9 and 10 via the analog A0 input. The PWM frequency and update rate(!) =  15.625kHz. Resolution is 10-bits.
