The Line Follower does exactly what the name suggests, it follows a line. Make it go where ever you want by showing the way with a 3 cm wide, black line.

Materials

• 1 x control board
• 1 x Education Shield
• 1 x IR Array
• 2 x continuous rotation servo
• 12 x jumper wire
• 1 x 9V battery
• 4 x AA battery
• 1 x AA battery holder
• 2 x power plug (One without the plug that has two loose wires)
• 1 x Line follower kit
• 1 x metal ball
• 2 x wheel

Other materials:

• 1 x black tape

This experiment can be created without the Education shield. You can download the schematics here, and the Fritzing original files can be found in this Github repository.

Instructions

Step 1

Gather all the construction materials for the Line follower.

Step 2

Let's start building the Line follower! If you want some building tips, go to the Building Advices reference.

Step 3

Step 4

Step 5

Make sure to screw the wheels to the continuous servos.

Step 21

Step 22

Step 23

Step 24

Step 25

Step 26

Step 27

Attach the shield onto the top of the board.

Step 28

Connect 5 loose jumper wires to the IR Array, one to GND, another to VCC and three different colored ones to AN1, AN2 and AN3. These will later be connected to the board so remember what color is connected to what.

Step 29

Step 30

Step 31

Step 32

Step 33

Step 34

Step 35

Step 36

Step 37

Step 38

Connect the loose wires from the IR Array to the board . VCC to power, GND to the breadboard, AN1 to A1, AN2 to A2 and AN3 to A3.

Step 39

Connect GND to the same column in the breadboard as the GND from the IR Array.

Step 40

Using 3 jumper wires, connect the right servo. The black wire to GND, the white wire to digital pin 6, and the red wire to the breadboard.

Step 41

Using 3 jumper wires, connect the left servo. The black wire to GND, the white wire to digital pin 9, and the red wire to the breadboard.

Step 42

Step 43

Check that your wiring is ready and connect the board to the computer.

Step 44

Copy the code:

/*
* LineFollower  
* The Line Follower does exactly what the name suggests, 
* it follows a line. Make it go where ever you want by 
* showing the way with a 3 cm wide, black line. 
* 
* (c) 2013-2016 Arduino LLC.

#include <EducationShield.h>

//IRArray(IR1, IR2, IR3)
IRArray ir = IRArray(A1, A2, A3);
//Wheels(left, right)
Wheels wheels=Wheels(6, 9);

void setup(){
  wheels.begin();

  //Use this line to set the threshold of the IR sensors. The default is 380. If you're using Arduino 101 board, use 530 instead.
  //Use test() to check the values of each sensor in loop()
  ir.setThreshold(530);
  
  delay(1000);
}

void loop(){
  int dir = ir.readLine();
  wheels.follow(dir);
}




Step 45

Then upload the program to the board. Remove the USB cable, you will not run this project with it connected.

Step 46

Prepare a 6 V battery with loose wires connector. Go to the Batteries reference if needed.

Step 47

Using the power plug with loose wires, connect the battery pack to the shield breadboard, black wire to GND and the red wire to the two servos’ power wires.

Step 48

Step 49

Step 50

Step 51

Step 52

Step 53

Step 54

Prepare a 9 V battery with a power plug and put it inside the robot. Go to the Batteries reference if needed.

Step 55

Connect the 9 V battery to the board's power socket.

Step 56

Now create some 3 cm wide, black lines, and lets follow it!

How it works

• The EducationShield library is included.
• The IRArray and Wheel objects are declared, ir and wheel.
• In setup() the wheels are initialized.
• The threshold for the IRArray is set with ir.setThreshold(threshold). If you’re using the CTC 101 board the threshold is 530, if you’re using the CTC UNO board its 380.
• The program pauses for 1000 milliseconds.
• In loop(), the variable dir is declared to hold the value read from the IR array using readLine(). The value will be between -100 and 100 and represents the direction the black line is heading.
• wheels is set to follow the value of dir.
• loop() continues to loop.

Note: Don't forget to change the threshold for the IRArray with ir.setThreshold(threshold) so that it fits with the board you’re using

Troubleshooting

• Refer to the illustration and double check your connections. Make sure the shield and jumper wires are firmly connected.
• If the motors are not working, see the reference wheels about how to debug servo motors used as wheels.
• Debug the IRArray, see the IR Array reference.

Learn by doing

• Print a track and build obstacles for the robot. If the obstacles are too difficult, see if there is a way to improve the robots performance by modifying the wheels.
• Make the robot react in some way when it “sees” only white. That is, when it has lost the track of the black line.
