I am about to start my project with an N Channel MOSFET to switch on and off a 12v LED strip. Can someone please explain to me how to hook up the 12v power supply, the LED strip and the Arduino Nano with the MOSFET? I have all of the solder sorted. I have bought mostly everything, with a few things arriving soon.

I have a heat sink at the ready just in case because the lights I am using are said to be prone to heat. I don’t have many ways to get logic level MOSFETS around me so I will try to find one online. How do I check if it is avalanche rated? I’ll buy a logic level to replace my normal one.

You do not need a logic level MOSFET if you add a BJT in front.

How would I hook up the BJT to the MOSFET?

Hi all. I have finished the circuitry, however, my light is not powering on. Just came on here for a few suggestions. The negatives of the light and the power supply are connected to the Channel N Logic Level MOSFET along with the arduino. The positives of the power supply and the LED strip are connected together. It is 12v at about 3amps. I’m not sure if it’s a soldering issue or if it’s a code issue but if someone could help that would be greatly appreciated

[image] How to make a schematic you can post. Introductory Tutorials When you submit a question on the forum you will usually need to add a schematic (circuit diagram). The tutorial that follows will explain some ways to create a useful image; however lets start by explaining how to add the image to your post. Its easy. Having created the image all you need to do is : Save the image somewhere convenient - maybe your desktop Start your post, and place the cursor (insertion point) where you want the image to be shown; [upload image to forum] 3: click th…

Try downloading Kicad or EasyEDA for free and then you will have a good way to create schematics for your projects in future. Alternatively get out the pen and paper and take a photo. Also post a photo of the real life wiring. Creating a mental picture from words is just a recipe for confusion and error

Thanks guys, sorry for the delay and not getting back to you. I have an update. The wiring works and the light works. I just soldered it wrong the first time. Now all I need is some code that switches a channel n logic level MOSFET on and off using a PIR motion sensor for arduino nano. Also, do I need to solder the nano to the perfboard. I’m sorry I don’t know much this is my first arduino project ever. Thanks for the help so far though

Would you like a circuit diagram?
