The two major projects completed in TEJ class

An autonomous robot which searches, locates and blows out a flame. Uses wall tracking strategy to find the flame, and uses the blower fan to put the flame out all handled by the BASIC software All of the PCB are custome built and components are PTH soldered

Main Components Used:

• PIC16F887 Microchip as the main controller
• L293D as the motor driver
• 2 distance sensors
• 2 IR sensors, one for detecting flame and one for line follower
• 2 BO Motors
• 16×2 Character LCD Module
• 12V Blower fan

Here are the PCB layouts used for etching, designed by me: Main Controller
