PiBot Help!!!
for project university making pibot! robot powered arduino run rasp pi setup webserver. website in hosting provide input arduino.
my problem, made error when designing pibot. bot has 2 motors rated 4.5v -15v, , im using 4 npn transistors (2n 3904) provide h-bridge control motors direction. using 9v battery power motors want control h bridge using arduino. believe arduino not man enough provide current need switch transistors. havent got long till assignment due need solution. spent lot on in both time , money , dont want new motors. have thought using relays again dont know if arduino man enough?

an arduino output pin powerful enough 2n3904 base current, 10 ma saturate.
question rather if the transistor powerful enough motor.
rather ampere volts question.
