Infrared sensor remote controlled car system has transferred to Bluetooth using system by rn42xvp-i/rm module. As same as infrared sensor system, the number of figures are confirmed to model car behaviors.
On the other hand, but contrary to Infrared ones, it’s easier to build up by directly to accompany character without assigning hexadecimal than before hands.
Red modules are Bluetooth system. It takes 5 hours.
