Hello everyone :),
i am trying to build an h bridge motor controller but i am having some trouble. I am using an arduino mega, an external power source of 4 AA batteries pack(6V) and 4 2N2222A transistors as you see at the schem. When i connect the motor (small motor not sure about the specs i think its 3V or 6V) directly to the batteries everything works fine but when i connect it to the bridge its turning really slowly. All 4 transistors are connected through 470 ? resistors to seperate arduino pins. Thanks in advance.
