How I built a Line Following Arduino Robot
Sitting at a teacher conference one day, my booth partner asked me how long it would take me to build a line following arduino robot. I looked around at the parts we had on hand: an arduino UNO, a pile of 10k resistors and photovoltaic resistors, continuous servos, coffee cups, wire, tape, and a nine volt battery.
I said “an hour.”
He said “Prove it.”
