Connect the Drain legs to the Green, Red, and Blue connectors on the LED strip. Connect the power rail to the +12v connector of the LED strip (note that in this image the power wire is black to match the colors of the connectors on my LED strip). Connect the Arduino ground to the ground rail.
How connect 12V led to Arduino?
- Connect the emitter of all the transistors to the Ground of Arduino.
- Connect the Ground of 12V power supply to the Ground of Arduino.
- Connect the positive terminal of 12V power supply to the 12V pin of RGB LED strip.
- Connect 1 K resistor to the base of the each transistors as shown.

What wire do you use for LED strips?
For single color strips, you only need 2 conductor wire, and for RGB strips, you need 4 conductor wire. We recommend using stranded copper wire 10-22 gauge.
Do LED strips need resistors?
In addition to the LEDs, one or more current limiting resistors is also necessary to ensure that the LED strip does not go into overcurrent mode. The resistor is also placed in series with the LEDs, and its resistance value is calculated such that it will draw approximately 3 volts as well.
How do I control LED lights with Arduino?
To turn on an LED, the Arduino needs to send a HIGH signal to one of it’s pins. To turn off the LED, it needs to send a LOW signal to the pin. You can make the LED flash by changing the length of the HIGH and LOW states.
How do you wire LED strips to mains?
How do I install my LED strip lighting? To get your strip light working, connect the transformer / driver to the strip light ( extending the cable with 2 core flex if necessary). Then you connect your transformer / driver to the mains via a plug or direct to the mains and you’re away.
Do LED lights attract bugs?
Bulbs that emit more short wavelengths of light (cool white/bluish color) will attract more bugs. … LED lights produce little to no UV light and a minuscule amount heat, which makes them less attractive to bugs—so long as they emit longer wavelengths of light.
How do you hook up LED strips without soldering?
How to connect LED Tape without soldering – LED Tape connectors
- 1: This is the Tape to starter lead connector for single colour. …
- 2: Cut the LED Tape along the cut line with a pair of scissors. …
- 3: Now take your Tape to starter lead connector and your new piece of cut LED Tape.
- 4: Open the Connector.

Can I use speaker wire for LED lights?
Yes you can(with the appropriate current rating being taken into consideration, as discussed elsewhere), but speaker wire is more expensive than normal wire “because of better audio properties”, so why not just get some cheap old regular wire..
Can I power 12v LED strip with USB?
USB ports supply 5 volts. The 12v LED strip requires at least 9 volts. I bought a step-up DC-to-DC boost transformer circuit which can step up from 1.5v and up it up 24 or 32 volts. It took 5 volts from the USB port and boosted it up to 12 volts to the LED strip.
How many amps do I need for LED strip?
To find the total maximum current draw per meter, we would multiply 60mA x 10 (ten segments per meter for the 30/LED per meter strip) = 0.6 Amps per meter OR 60mA x 20 (twenty segments per meter for the 60/LED per meter strip) = 1.2 Amps per meter.
What happens if you don’t use a resistor with an LED?
When hooking up an LED, you are always supposed to use a current-limiting resistor to protect the LED from the full voltage. If you hook the LED up directly to the 5 volts without a resistor, the LED will be over-driven, it will be very bright for a while, and then it will burn out.
Can LED strips catch fire?
The LEDs will not give off enough heat to catch on fire or burn your bed, ever. This project could easily be the fusion of 2 well engineered products to do something cool without any risks!
Will a 9V battery power a 12v LED?
you can use 9v battery for 12v Led . Just only the brightness is less than 12v battery . … if you need only Light purpose then you can use 9 volt instead of 12 volt supply.
