Brilliant students of YRC: Ved Soman

Ved Soman joined the LEVEL-2 course of YANTRAM ROBOTICS CLUB on 24 June, 2015. I taught him the basic hardware of the robotic kit given to him. Then in the evening batch I taught him the basics of embedded programming. And on the same day, to my surprise, he developed this program (given below) with systematic logical thinking, as to control the two motors connected to PB4-PB1 through two simple IR sensors in his robotic kit of ATMega8 MUC.

Ved just passed 10th standard and planning to take admission in Poly with Mechanical trade. He has the peculiarity of learning with keen attention and has good logical thinking abilities.

Join him on his Facebook profile.

The YashPlus Team & YRC wish him all the best…!
