Making a Battle robot sinhala 2

This video described about battle robot circuit making and how to program your robot controller.This video link with previous"Making a battle robot" video.
The program is given below.
මෙම වීඩියෝවෙන් යුධ රොබෝ පරිපථ සෑදීම සහ ඔබේ රොබෝ පාලකය program කරන්නේ කෙසේද යන්න විස්තර කර ඇත. මෙම වීඩියෝ සබැඳිය ඇත පෙර “යුධ රොබෝවක් සෑදීම” වීඩියෝව සමඟ.
