This means that in an ideal situation, i.e bot going straight on track, the center 2 sensors are on black line, the ones immediately to the side of each sensor are on the border of the black line and the farthest sensors are on the white surface as shown in the image below. Each array features visible LEDs that point upward when the board is attached (properly) so you can see what the robot sees, brightness control right on the board, and an I2C interface for reading and power control. A line follower robot, or a LFR in short, is a simple autonomous robot that optically tracks a line made on the surface of the floor. IR Sensors(8) 16x2 LCD(1) LM324 Operational Amplifier IC(2) . For example, you do not need to connect ground to all six ground pins along the lower edge of the board. QTR-8RC is a reflectance sensor array but intended as a line sensor. After Connecting motors, the connection should look like this. 3 sensors for maze solver Image Source : Google I imported the adafruit motor shield library and ran its motor test example and it worked fine. We can use PID instead here we will see the work of 5 sensor 3rd sensor as detecting center line but sometimes the line are . Line follower is a bot which follows black line which is made on a white surface. It's kinda both.
