[CyberTroniX]

i'm a bit confused ..
if i can connect the bluetooth module ( which has 4 pins : TX , RX , PWR , GND ) to Rx1 , do i connect it to Rx1 which was used for the RF Module that came with the robot ? or do i connect it to RX & TX that are on the Analod/Digital section of the microcontroller ?

if it's the 1st option then i need to know the pinouts of the Rx1 input ,
if it's the 2nd option then i need to know where to connect the PWR & GND pins of the bluetooth module ?


Something else i'm thinking of doing it ... which is replacing the RF Module on the Remote Control Unit with a bluetooth module . Is it possible ??
