How to connect led strip lights to power supply. If you need to connect more, you need to connect them in parallel and then connect to the power supply. For powering the led strip you will need a power supply that can provide enough power for the length of led strip you will light up. Plug in the adapter to power the strip.
We have two main power supplies available; However, it is recommended that you make allowances for unintentional overloads. Determine the power draw of the led strip next, look for either a wattage (w) or amperage (a) specification for the led strip.
For our mock project, we will use 10 feet of the architectural series strip light as an example. Additional strips should have extra supportive power wire or additional power supply units added down the line. Which means, when wired in parallel, each strip you add to the string will add the same amperage again.
If you have a power supply lying around at home, for example, you can also check the backside label and see if the voltage is listed there. The led strip has a power consumption of 14w / m. That means you'll need to use one of our led power adapters if you want to use led strip lights.
Power supplies are usually rated in amps while the led strip is rated in watts. Connect the gnd (black wire on the diagram, but it is usually white on the led) to the gnd pin on nodemcu. For those going with a plug in power supply, the output connection is usually a 2.1mm male barrel plug.
Once the wires are securely attached to the adapter, plug in a power supply cord into an outlet. Then, plug the power cord into the slot on the adapter. Plug and play and mains ready.
