irf530

Resistor 100k ohm

To control a big load like a motor or a ledstrip with Arduino, you probably already used a MOSFET.Arduino Uno and other 5V boards let enough current go trough their control pin and this makes the task quite easy.However, as Arduino Zero, MKR1000 and most other 3.3V board don't let enough flow on their control pin, you will need to use two MOSFET to switch the load.The Arduino will command a small transistor (a BS170) first that will eventually control a bigger one (IRF520) connected to the led strip.
