CHAPTER 3

High-Power LED Controller

This project uses an Arduino to control the power to 12 V LED modules using high-power MOSFET transistors. You can use pretty much any 12 V direct-current (dc) lights with this project that are marked as being “dimmable.” You can also expand it to control six rather than just the three channels I used (Figure 3-1).

Parts

To build this project, you will need the following:

The MOSFETs have a maximum current rating of 30 A. However, the wiring through the Arduino ...
