# Line Folower Robot

## Materials

- Standard 4WD Chasis

- Microcontroller that supports Arduino Code

- L298N Motor Driver

- IR Sensor Array (5 Sensors)

- Portable Power Source

## Step 1: Assemble the Chasis and fix the Sensor to the bottom of the Car's front 
 Attach L298N Motor Driver Module and Arduino on the top of the car.

### Wiring circuits

| From     | Pin  | <== Pin Name   | To      | Pin |

| -------- | ---- | -------------- | ------- | --- |

| L298N    | IN1  | Left Forward   | Arduino | 2   |

| L298N    | ENA  | Left Speed     | Arduino | 3   |

| L298N    | IN2  | Left Backward  | Arduino | 4   |

| L298N    | IN3  | Right Forward  | Arduino | 5   |

| L298N    | ENB  | Right Speed    | Arduino | 6   |

| L298N    | IN4  | Right Backward | Arduino | 7   |

|          |      |                |         |     |

| IR Array | OUT1 | Very Left      | Arduino | 8   |

| IR Array | OUT2 | Slight Left    | Arduino | 9   |

| IR Array | OUT3 | Middle         | Arduino | 10  |

| IR Array | OUT4 | Slight Right   | Arduino | 11  |

| IR Array | OUT5 | Very Right     | Arduino | 12  |

#### Note: Wiring depends on your orientation 
 This is why I have included "Pin Name" to describe which Pin I am actually referring to. You can use your own pinouts too.

### Wiring motors

| From         | Pin | To    | Pin  |

| ------------ | --- | ----- | ---- |

| Left Motors  | Vcc | L298N | OUT1 |

| Left Motors  | GND | L298N | OUT2 |

| Right Motors | Vcc | L298N | OUT3 |

| Right Motors | GND | L298N | OUT4 |

## Step 2: Power

- Power is upto you, you can use any thing that has between 7 - 12 Volts

- You simply need to connect it in the following way

  | From    | Pin | To       | Pin |

  | ------- | --- | -------- | --- |

  | Supply  | Vcc | L298N    | 12V |

  | Supply  | GND | L298N    | GND |

  | L298N   | 5V  | Arduino  | Vin |

  | L298N   | GND | Arduino  | GND |

  | Arduino | 5V  | IR Array | 5V  |

  | Arduino | GND | IR Array | GND |

## Step 3: Upload the code

## Step 4: Try it on different tracks!
