rc_car1 I put D2 signal to ground and working good
upload to arduino rc_car1.ino
welding wire from arduino to rc car (ground,power and D2) same as rc_car1.jpg photo
send command letter under serial ... the car need to rispond with moving
a Forward
b Forward Turbo
c Forward & Left
d Forward & Right
e Backward
f Backward & Right
g Backward & Left
h Left
i Right
