Many car enthusiasts enjoy adding extra lights or upgrading the interior bulbs to LEDs, however with the Arduino platform you can enjoy a greater level of control and detail by controlling high-powered LEDs and lighting strips. Doing so is easily done with an external power supply, an N-MOSFET for switching the higher current and a compact Arduino-compatible board such as our LeoStick. Hyundai Veloster enthusiast "Tokra" did just that, by building a system that generates various lighting effects when the car door is opened and closed, for example:
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.
