Connect a 9-12V power supply to the Arduino so that Vin supplies the high voltage to the LED strip. If you want, you can also just use a separate wire that connects to a power supply that provides about +12V. Make sure to connect the ground of that supply to the ground of the Arduino/MOSFETs!
In respect to this, how do I get Arduino 12v?
To get a 12V output from an Arduino Uno Board you need to use the Vin and GND pin as terminals. Vin would give the maximum voltage being provided to the board ( if board is supplied 9V then Vin would supply 9V and likewise).
Beside above, what resistor do I need for LED? Basics: Picking Resistors for LEDs
| Power Supply Voltage | LED Color | Resistor (calculated) |
|---|---|---|
| 5 V | Red, Yellow, or Yellow-Green | 128 Ω |
| 5 V | Red, Yellow, or Yellow-Green | 56 Ω |
| 9 V | Red, Yellow, or Yellow-Green | 72 Ω |
| 9 V | Blue, Green, White, or UV | 96 Ω |
Accordingly, how many LED can be connected to Arduino?
A standard Arduino board (like a Duemilanove) provides 17 "free" I/O pins, not counting TX, RX, Reset, or pin 13. So, you can hook up 17*16=272 LEDs. This can work well, especially if you're keeping one LED lit, or quickly scanning between just a few.
What is the L LED on Arduino?
The 'L' LED The Arduino has rows of connectors along both sides that are used to connect to electronic devices and plug-in 'shields' that allow the Arduino to do more. However, the Arduino also has a single LED that you can control from your sketches.

What is LED indicator on phone?
The LED is the little light, usually at the top of your phone, which lights up when you get a new notification (a call, text, news alert, etc.). What you may not know though, is that there are dedicated apps for managing the notification colors and customizing your phone's LED light.What resistor do I need for LED Arduino?
The Arduino is a convenient source of 5 Volts, that we will use to provide power to the LED and resistor. You do not need to do anything with your Arduino, except plug it into a USB cable. With the 270 Ω resistor in place, the LED should be quite bright.What language does Arduino use?
