Controlling high power DC load using MOSFETs
For scenarios where you need to handle a lot of DC power and current, MOSFETs are a great solid-state alternative to mechanical relays. With proper power and heat-sinking, many common power MOSFETs can power over 1000 LEDs!
Note
AC or DC power are both dangerous! Just like the previous recipe, use extreme caution when using high-power loads. In this case, we will be using a 9V DC load--not too dangerous, but many MOSFET circuits can handle high-voltage and amperage solutions.
Getting ready
For this recipe, we will need the following equipment:
- 3 N-channel power MOSFETs (the IRLB8721 MOSFETS are inexpensive and available from Adafruit (https://www.adafruit.com/product/355)
- 12V analog LED light strip; with ...
