About Transistors. The Arduino can only provide 40mA at 5V on its digital pins. Most motors require more current and/or voltage to operate. A transistor can act as a digital switch, enabling the Arduino to control loads with higher electrical requirements I have an Arduino that I want to control a 5v power supply on and off. Can I use a General NPN by the switched circuit on the emitter, it is more likely to be 4.5V despite the collector being at 5V. However, if you used a PNP transistor with the emitter being fed by the 5V there is a fairly good..
