I want to control a DC motor using Raspberry Pi and a L239D microcontroller, like in this page:

I saw in other webs that is recomended to sold a capacitor on the motor to supress noise.
Do I need do that, even if I use the microcontroller?
thats a precaution in case the noise spikes from the motor brushes make their way via the power lines into the digital circuits and those circuits misinterpret the spikes as control signals causing things to function incorrectly.
