How do you make a simple line follower robot with Arduino?

How do you make a simple line follower robot with Arduino?


  1. Step 1: Connect the circuit as shown in the schematic.
  2. Step 2: Use the Arduino IDE to write your own code.
  3. Step 3: Upload your code to the Arduino and connect it to the batteries or you can even use a power bank to run the Arduino.
  4. Step 4: Test it on a black path.

How do you make a line follower?

Step 2: Hardware Installation

  1. Assemble the 2WD Smart Car Chasis 2 Wheels.
  2. Connect the IR sensor to Analog to Digital and Comparator Module.
  3. Then, connect the output pin to Arduino UNO analog pin.
  4. Connect Vin to 5V and GND to GND in Arduino UNO.
  5. Then, connect the motor driver pin to Arduino UNO pin.

How do you make a line follower robot with Arduino Motor Shield?

Just connect the pins to the Motorshield and place the sensors in front, one left, one right. Use a small cardboard piece to mount sensors on. Connect the sensor’s VCC pin to +5v and GND to GND pin on motor shield. Connect the Out pin of right sensor to A4 and left sensor to A5.

How does line follower robot work?

Line Following Robotic Vehicle Circuit Working

  1. Initially draw the path on a light colored surface with black color tape.
  2. Place the robot on the floor.
  3. Now power on the circuit.
  4. Robot moves in the specified path.
  5. When it moves out of path, sensors check it and automatically adjust the robot.

How do you code a VEX line follower?

Open the Motors and Sensors Setup menu, and go to the Analog Sensors tab. Select Robot > Motors and Sensors Setup to open the Motors and Sensors Setup menu. Click the “VEX 2.0 Analog Sensors 1-8” tab on the Motors and Sensors Setup menu. Use the dropdown list to make “Line Follower” the sensor type.

Which sensor is used in line following robots?

QRD1114 IR reflective line/object sensor and CNY70 reflective optical sensor are the most commonly used sensors for line follower robots. The CNY70 is a reflective sensor that includes an infrared emitter and phototransistor in a leaded package which blocks visible light.

Why do we need a line follower robot?

The sensor based black line follower robots are one of the most basic robots used to follow black line on white background or vice versa. These robots may be used to in various industrial and domestic applications such as to carry goods, floor cleaning, delivery services and transportation.
