5.3 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 Bluetooth module with Arduino Uno.
As, Bluetooth module have 6 pins but for this project we have to use only 4 pins i.e:
- VCC
- GND
- Tx (Transmitter)
- Rx (Receiver)
4. Connect the VCC of bluetooth module with the +5V of Arduino Uno.
5. Connect the GND of bluetooth module with the GND of Arduino Uno.
6. Connect the Tx of bluetooth module with the Rx (pin 0)of Arduino Uno.
7. Connect the Rx of bluetooth module with the Tx (pin 1)of Arduino Uno.
8. Now, connect all the 4 motors with Motor driver:
S.No. | MOTOR DRIVER | MOTORS |
1 | OUT2 | Positive (Red) of Motor 1 and 2 |
2 | OUT1 | Negative (Black) of Motor 1 and 2 |
3 | OUT4 | Positive (Red) of Motor 3 and 4 |
4 | OUT3 | Negative (Black) of Motor 3 and 4 |
9. Next, connect the motor driver with Arduino Uno:
MOTOR DRIVER | Arduino Uno |
IN1 | Digital Pin9 |
IN2 | Digital Pin10 |
IN3 | Digital Pin11 |
IN4 | Digital Pin12 |
5V | +5V |
GND | GND |
