Arduino Base Auto Direction Robot

it is the robot that move by avoiding obstacles. it sens the object and view surround and keep going where free space is available.

1. 4 dc motors
2. 1 motor driver
3. cables
4. few jumper cable
5. ultrasonic sensor
6. arduino(here i use pro mini 5V)
7. servo
8. pcb
9. motor clamp
10. wood piece
11. some tape
12. battery(12V)
13. ultrasonic sensor stand
14. some skrue

attach motor clamp to wood piece with skrues.

connect motor in clamp and connect wire to motor.and check connection proper or not. and deside the front part of robot and connect servo motor

connect ultrasonic sensor to stand and mount on motor. make wire that to connect with arduino. also connect the wire to motor driver.

make the circuit as picture diagram. use male and female header for connect components like servo, ultrasonic sensor, motor driver etc.

arrange the component on frame and wire all the component to circuit. connect battery or any other 12V dc supply to motor driver and connect 5V supply to arduino board.

program the arduino by this program. i use FTDI programer to programe arduino pro mini.
