3.3 Circuit Connection

Activity-3-> Obstacle Avoider robot 3.3 Circuit Connection

1. Collect all the components required.

2. Now, connect the components and make the robot assembly  as instructed in the chapter-5.

Note: Take the chassis and connect the motor clip with the Chassis then connect the motors on the clips.At the last attach the wheels as shown:

3. Now, connect ultrasonic sensor with Arduino Uno.

As, ultrasonic sensor have 4 pins:

  • VCC
  • Trigger
  • Echo
  • GND

4. Connect the VCC of ultrasonic sensor with the +5V of Arduino Uno.

5. Connect the GND of Iultrasonic sensor with the GND of Arduino Uno.

6. Connect the Trigger pin of ultrasonic sensor with any of the digital of Arduino Uno. Here,I am connecting it with digital pin 5.

7. Connect the Echo pin of ultrasonic sensor with any of the digital of Arduino Uno. Here,I am connecting it with digital pin 6. 

8. Now, connect all the 4 motors with Motor driver:
