I'm trying to build a DC motor control circuit. I'd like to get the motors running from 0% to 100%. I'm considering running the motors with a pulses from a 555, using the 555's duty cycle to vary the speed. Being able to change the directon of the motors via a simple switch is important... I realize that there are chips available. Numbers anyone? TI manufactures one, as does National Semiconductor.. How easy are they to get, and how easy are they to control / wire / what external parts are required? Leads, sources, and schems are appreciated. thanks! --John
