Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Component Need
- 4 dc motors
- 1 motor driver
- few jumper cable
- ultrasonic sensor
- arduino(here i use pro mini 5V)
- motor clamp
- wood piece
- some tape
- ultrasonic sensor stand
- some skrue
Step 2: Make Frame
attach motor clamp to wood piece with skrues.
Step 3: Motor Connection
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
Step 4: Ultrasonic Sensor & Motor Driver
connect ultrasonic sensor to stand and mount on motor. make wire that to connect with arduino. also connect the wire to motor driver.
Step 5: Main Processing Bord
make the circuit as picture diagram. use male and female header for connect components like servo, ultrasonic sensor, motor driver etc.
Step 6: Final Connection
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.
Step 7: Program Arduino
program the arduino by this program. i use FTDI programer to programe arduino pro mini.
