I am building a prototype device and need to control the r.p.ms of a 12 volt motor,basically I have a motor from a variable speed drill and I hoped to control its speed by useing the trigger switch off the drill but because i need the motor to run at low speed for extended periods the trigger switch creates too much heat and burns out. I was wondering wether the speed could be controled through circuitry![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
