INTRODUCTION
Used 2 motors operate with 3V.
Used 9V batteries
Variables resistors is use to control the motor
speed.
A microcontroller is used to program the
direction of the vehicles .
Switch is us as the sensor .
OPERATION
-When the switch is ‘ON’ ,the vehicles will move
forward .
-When it hit a obstacle switch at the front will ‘ON’
the sensor, the vehicle will move back ward for a
second.
-After that, the vehicle will stop for a second and
will turn the tyre to the right and then the
-vehicle will move forward.
OPERATION CURCUIT
-9V input go to switch ON/OFF to operate
Circuit.
-When switch ‘ON’ it will go to microcontroller.
-Microcontroller act as the controller to move
the motor operate and will move the tyre
forward ,reverse ,right ang left.
-When hit something the switch will invert the
