    Hi there!!

    this is my problem i want to interface a cellphone vibrator to a pic microcontroller but i dont know how to implement the analog circuitry so that the motor can be driven with enough current, at the moment what i have done is using a transistor but the vibration is too weak
    additionally i want to power the circuit with only 3 V. Can anybody help me with some schematic or guidance? thanks in advance:):)

    ps sorry for my english.:p
