Simple LFR PID using PICBasic Pro

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.

fyi, the robot move kinda sluggish because i post the non optimum value of pid at that time. The optimum value of Kp, Ki,and Kd needs to be tuned in order to have a good output. 1,1,7 at maximum battery of 7.4V

I love your PCB design - very beautiful, neat and tidy. Are all the holes plated through?

thanks allen, however the holes are not plated i have to solder a wire to get the top and bottom a connection.
