Arduino Basic Line Follower
Step 1: Collecting all the required hardware for this project.
The first step in this project is to acquire all the hardware necessary for this project. The important hardware in this project is an arduino uno R3, You can get an arduino micro controller from different sources like as ebay.in ,amazon.in or from local stores. Next hardware necessary for this project are a pair of line sensors,we are using a pair of Infrared sensors. Infrared sensors works with the principal of infrared light reflection,there will be an infrared emitter and a reflector. The emitter emits the light and this light is reflected in the surface, this reflection is absorbed by the infrared receiver. The black or white line is detected by the change in the values from the reflected light
Arduino Uno R3
Pair of Infrared Sensors
L293D motor driver board
Pair of Bo-motors or Gear motors
Chasis for Robot
Battery supply of 9v
Step 2: Interfacing arduino and programing
The next step is to interface the arduino microcontroller with pc, for that first we have to install the arduino compiler. You can get the newest version of the arduino compiler from arduino download and install it in your pc. Run the software and connect the arduino to the usb interface of you pc. In the compiler select the board model as arduino uno R3 also select the port. copy and paste the code given below
Step 3: The circuit diagram and connections
Disconnect the arduino board from the pc after burning the program into the board. Connect the motors and the sensors to arduino according circuit diagram shown above. Power the arduino and L293D circuit from the 9v battery, you can either get an arduino power connector pin from local stores or you can solder the positive and negative pins on to arduino board
Step 4: Making it work
Fix the motors into the chassis, you can use a chaster wheel in the front that will help the robot to turn freely. Get a black Insulation tape and draw a path in the white surface,Power up the circuit and it works!!!
