Hello /g/, I'm a bit of a moron doing a fun summer project. In a nutshell I want to get these lights to sync with music, the trouble is I cant figure out how to turn them on.
In the picture to the left you can see my black power source, which can deliver up to 5 volts
On the bread board I just have some jumpers that attach to the lights positive and negative voltages. As well as three MOSFETs.
My problem is whenever I plug in the voltages from my power source to the lights voltages, my power source cuts off telling me I am drawing too much current. I understand I should have a resistor of some sort then, but how much?
Im using the following tutorial here:

Technical information for the lights here:
>https://www.adafruit.com/products/1460?gclid=CJLLoLe2oskCFQH3HwodrIUFHw
any comments or advice appreciated, thanks.

You might have more luck in /diy/, friend.

OP here,
just wanted to comment that my power supply is probably not enough (in the tutorial it states I need 12V) is there any chance I could use an old computer adapter for this and some other part?

thanks found a good thread there for it. Looks slow though.

That's literally my carpet wtf

You are on the wrong board, people on /g/ don't have a clue about electronics or other real stuff, they only know which parts to pick to play cod on max

First two have actual code for two types of LED strips, second two are just ideas. I've done this myself, but only on easy mode with the BlinkStick Flex™ like in the second video.

What is the current rating of the supply?
Is your arduino ground referenced to the supply?
You need about 20mA per LED when they are turned on all the way (i.e. white).
Always connect the grounds first,Arduino should only be connected to ground and the base of the transistors. Sometimes it's a good idea to throw like a 1kOhm resistor on the output pins of the Arduino.

First of all fuck the captcha system that 4chan uses. Second, yes you can use a computer power supply unit to get 12 volts. You need to connect the green wire to any black wire on the large connector, and 12 volts is supplied by the yellow wires. The resistor value you need in ohms is roughly the voltage you use divided by the current needed.
