Hey guys . asking you for options , i have a 12 V motor which need to be controlled only speed using PIC. dont care about the direction . I do not plan to use the H bridge circuit to control the speed , i am using darlington array to control an array of high powered resistors , 10W but the darlington array can go to the max 500 mA . i not so sure of the output 500 mA given in the data sheet , means it can support 500mA from the external circuit or it can produce the most 500 mA . My maximum current rating for my motor is 1.5 A , Is there any alternative such as PWM to control the speed of the motor. Thanks guys the model of my darlington array is uln2803A .
