So I want to control a 12V using an Arduino Uno, a breadboard, and ONE external power supply (ie 12v battery) using only transistors and resistors (so no specialized chips basically). How can I do this?

No PM's please.


crap. sorry mean dc motor


Typical output configurations.

There are examples that come with the IDE how to blink a LED, controlling a motor is similar.
No technical PMs.

Low side NPN transistor as a switch, resistor for signal on base, will need flyback diode across the motor, then you're golden.
