I am a newbee to this forum so please be patient. I need help with a circuit I want to make using a small 3 volt dc motor connected to a timer. I am using a programmable timer that uses 2 AAA batteries to operate and outputs 3 volts dc to a to a 3 volt dc motor. The original function of the timer is to rotate the motor in one direction then the timer is set to rotate the motor in the other direction. This is done by alternating the dc output to the motor from positive to negative. This is where my problem starts.
I need more torque from the motor. I found that if I apply 6 volts to the motor for the duration that I need (aprox 3 sec) I get the torque I need. How do I make a circuit that will use the alternating 3 volt output from the timer and use a separate 6 volt battery source to the motor so the motor will rotate forward and backward. Do I use relays and diodes? I'm stuck with the motor turning in the same direction. Any ideas would be a help me.
