Line Follower Robot Using MSP430 Microcontroller

Hi, in this instructable we're going to make a line follower robot using an MSP430 microcontroller.

MSP430 Launchpad, IR Tracking Module, L298 Motor Driver, 2-Wheel Robot Chassis, Power Supply (a battery or a power bank)

For the project, you'll need an MSP430 Launchpad, Infrared Sensors, a Motor Driver (I'm using L298N) , 2 - Wheel robot chassis, and power supply (In my project I'm using a power bank, however you can use other battery according to your preference, using a powerbank with two usb outputs gives me the opportunity to connect the Launchpad and the motor driver at the same time.)

In order to make the robot run with the C code that I'll provide in the next step, you have to make the connections as shown in the diagram. Below, you can find the same explanation for the connections:

Sensors to Sensor Board:

VCC,GND and IN1 --> VCC, GND, IN1

VCC,GND and IN2 --> VCC, GND, IN2

Sensor Board to MSP430 Launchpad:

VCC --> 5V

GND --> GND

IN1 --> P1.3

IN2 --> P1.4

Motor Driver to MSP430 Launchpad:

Enable (left & right) --> P1.6 (In the code you can change the duty cycle of the PWM to inc./dec. speed)

Right Motor Control --> P2.2 & P2.3

Left Motor Control --> P2.4 & P2.5

Power Supply VCC & GND --> Battery or Power Bank

You can find the code in the following link:

If you have wrong connections to the motors in the setup, you can change the P2OUT in the functions to correct your faults without messing with the cables.
