hello everyone
i am making a robot lne following.
the one which i have made right now i power through ac mains and using voltage regulators i give 9v to motor control ic and 5v to the arduino uno and it works perfectly.
just as further advancement i was thinking of using wireless methos by that i mean using battery to power it. but the transistor battery runs out too fast. so iwas thinking is it possible to use a powerbank the one for phones and step it up to 9v somehow and achieve it?
anybody has tried it or anybody has suggestion then please help
i am new to this forum btw
