In general, we can use both PNP or NPN transistors as switches. However, PNP transistors can only control the same voltage as is supplied to the Arduino chip. Let’s look at the most fundamental transistor-switch circuit: an NPN switch.

V-operating Arduino to switch on a 12V motor. A transistor can act as a digital switch, enabling the Arduino to control loads with higher electrical requirements. The transistor in this example completes the . The tried and true cookbook solution for a typical low power NPN switching transistor (2N440 2N390 2N22etc), with 5V logic driving .

The LED’s will be on using the switch on the casing.

Challenge: Make this go on and off using a transistor and the Arduino. So you have a DC motor or lamp but no matter how you connect them to your Arduino they just won’t work? Guess what, the Arduino is a brain that . In this arduino tutorial I go through a way of finding out the resistor value to get an Arduino control a NPN.
