The Line following robot consist of 4 sets of sensors used to detect lines, two sets on the left and on the right. The delection sensitivity can be adjusted sensor has a LED indicator for detection. Makes it easy to monitor sensor activity. The sensor operates from infrared light transmission and reception data. Which is caused by uneven reflection of light between white and black. Where black is less reflective than white. Allowing users to learn about the functioning of the sensor as well.
The Nano V3.0 with no. ATMEGA328 microcontroller IC was selected as a board to control the operation. It has 32KB SRAM 2KB EEPROM 1KB flash memory. The board also has a CH340 for converting USB to UART signals to be used to connect to the computer for loading the driver we wrote. Users can write programs through the Arduino IDE program.
On the main board there is a connection for the bluetooth module. The JDY33 can be put into the Bluetooth module for the development of the robot to be controlled via Bluetooth. SW1 and SW2 switches are also available for users to write additional programs.
Besides that, users have learned how to write driver programs. Also learn about mechanics such as the operation of gear motors, learn how to create applications to control robots, and learn how to work electronic circuits.
