After experimenting with various LEDs and other low-current devices, the beginner or enthusiast may be wondering how to control items or devices that required more power than can be offered with an Arduino's digital output pin. One method is to use an N-MOSFET, a handy component that can handle much more power and also be controlled easily with a digital output.
This process has been explained by the random-how-to blog, with both the hardware connections showing how to control popular LED strip lights and also some demonstration code. Furthermore they lead into thought about creating remote-controlled strips with Bluetooth and serial. Finally the results of their ideas are shown in the following video:
If you're making a similar project and need to control large currents with your Arduino digital outputs - you'll need a MOSFET. We've got you covered with out NDRIVE: N-MOSFET driver/output module:
This high-power N-MOSFET module lets you switch high-current loads using a tiny microcontroller. Perfect for controlling that set of traffic lights mounted in your living room! Works brilliantly for automotive projects such as switching high-power 12V lights and high wattage LEDs. For more information and to order, visit the product page.
