am trying to do a variation of a photovore without using any microchip or motor driver and to change speed it will have to change voltage from about 2,5V the lowest to 6V highest.
can a geared dc motor operate in all this voltages without loosing all the torque at 2,5V and not frying at 6V
and only really affect speed?
it doesn't matter if the geared motor is slow (but not to slow)
