Simple PID LFR using PICBasic Pro 2.46

Project Name: Simple LFR PID using PICBasic Pro

Author/Designer: holy_rainman

Project Description: To implement classic PID control algorithm to the Line Following Robot using Basic Language. The sensors used are from CYTRON SN-IRS-02 (thanks for the cute sensor) and are processed using analogue method. The motor driver used are L293D + micrometal gearmotor 30:1 which are common in mobile robot . I made the PCB board stacked together cause it gives a compact image towards the robot. I put on a common LCD to scroll the menu and to ease the troubleshooting process. The hardware cost around RM 250. The robot from the video are a bit sluggish cause the optimum pid value was not tuned at that time. Need a bit tuning, tweeking and some trial and error to obtain the correct value.
