Once you’ve gotten as far as identifying the strip you have and reading some of the basic tutorials and trying out some of the examples you’ll either know how to do it or have some much more specific questions to ask. OK, after looking at the info on Amazon and looking more closely at the strip and the price. I don’t think these are individually addressable LEDs. More likely the RGB lines are grounds. You could probably control brightness with PWM pulse width modulation, turning them on and off quickly. You’ll need to do more research on this to get the details right, but I think you could use a transistor to do the switching to protect your Arduino for the 12 V and from the current necessary to drive the LEDs. You would connect an Arduino pin to the base of the transistor to control it. You’d need to select a transistor that can handle the current of all of the LEDs of that color.

Same should work for CC3D too. RGB LED does not only help you identify your quadcopter easier, it can also indicate many flight data using different colours, such as battery level warning voltage alarm , flight mode indicator, orientation lights, RSSI singal strength, thrust levels etc. To learn other ways of turning LEDs on and off using Radio transmitter. They only needs 1 data input, and takes 5V power supply. Alternatively you can also take a look at this and this on Banggood.
Description. RGB LED module LED is made of a plug-in full-color, by R, G, B three-pin PWM input voltage can be adjusted in three primary colors (red / blue .
Power requirements Each LED pixel can draw up to 60 milliamps at maximum brightness white. Therefore you should not try to power the LED strand directly from the Arduino, because the strand will draw too much current and damage the microcontroller and possibly your USB port too. The LED strand will therefore need to be powered by a separate power supply. The power supply must supply the correct voltage 5V DC and must also be able to supply sufficient current 1.
Excessive voltage will damage or destroy your LED pixel strand. The LEDs will only draw as much current as they need, however your power supply must provide at least 1. If you chain two strands together, you will need a 5V 3A power supply. Four of the wires at each end of the strand are terminated with a JST connector.

The diagram below is a graphical representation of the connections for LCD like mine. This diagram shows how to connect my LCD to the Arduino. These LCD are tricky to hook up because there are so many wires. Check the spec sheet that comes with you LCD carefully to verify connections are correct. Once the LCD is wired up, it is fairly straightforward to use.
Sep 19, · Re: Arduino Pro Mini, Transistors and 12 Volt RGB LED lights Post by vinds» Mon Sep 19, am I was wondering if you found an answer to this problem.

Read More , you will be able to do this. We will also use the Arduino IDE to control them. Many of these strips come with an infrared remote to control them, though in this project we will be using an Arduino to instead. These strips sometimes referred to as Neopixels have integrated chipsets which allow them to be addressed individually. This means they are capable of more than just ambient lighting. Today, we’ll be turning them into a big pixel display that can be hung on the wall. Read More display from scratch.
You can even use them to make your own personal indoor storm cloud lamp. These strips only require 5v to power them.
LESSON 19: Arduino LCD Display
The concept is pretty simple, the Arduino powers two IR transmitters at 38kHz. One at the bottom of the stairs and another at the top. When the receiver detects a beam break by someone walking between the transmitter and receiver, the receiver sends a signal to the Arduino which calls a function to make the LEDs display a pretty color.
The parts I used: Adafruit 36mm 12V LEDs http:
The RGB LED has four leads: the three short ones are anodes that correspond to each of the three colors (red, green, and blue) and the fourth, longer lead is the common cathode. Connect the ohm resistors in series with the anodes of the LED and the common cathode to ground.
Kai Benjamin Heinz Hey Kai! Thanks for the help! How could I quickly check if it’ll draw too much power? Will it burn out the LED’s? Which transistors would you recommend? And here’s a link to site where you can download the schematic program super simple! I attached my schematic file in the last line of my question. I already drawed the 2 images, but have still not enaough reputaion to post them so I uploaded them here: Using Transistors is recomended, so you will surely have no problems.
My way, the NOT recommended way, is to simply try and see what it gest without transistors. If it runs you are fine, if not you can change it anyway. But Before hooking everything up together, I have a question about the AA battery source that you included in the image. Do I need that, or am I fine with using a regular usb to power my arduino?
– Now with 100% less Wookiee!
If you have used a breadboard before or are familiar with how it works, you can skip this section. Inside the breadboard, groups of holes are connected, so when you plug wires or components into holes from the same group, an electrical connection is made. Most of the holes are in groups of 5. Usually you will connect components by plugging them into nearby groups of 5, and then add wires to connect those groups to others to complete your circuit.
Along the top and bottom of your breadboard are long groups which are usually used for power.

Learn to build an Arduino program that does things when it receives serial commands. Send commands to drive a SparkFun RedBot buggy around from your computer. It uses the input from two precise DHT22 based temperature sensors. The software is a simple, custom written PID controller.
Arduino: Controlling an RGB LED by Hue
This will introduce us to a new circuit component, and will require us to learn some new programming skills. It has 4 leads. One lead, the long lead, is the common ground. You can control the color you get out of the LED based on the voltages you write to the different control pins. A schematic will probably help you understand how the component works and how you should hook up to it.
I think these are much more confusing, but just mention them so that you know that this tutorial is for the common cathode type.
Today I have an interesting product sitting on my workbench: the RGB Led Lighting Shield with XMC for Arduino, a shield manufactured by Infineon, with the order code KIT-LED-XMC As the name suggests, this is an RGB LED controller shield, capable of driving up to 3 LED channels, in constant current mode.
I am taking some courses for my masters, started a few contracting gigs and went to China with DangerousPrototypes Hacker Camp. Time to change that. Time for some cool LED stuff! The only datasheet I could find was from Adafruit here and the english is really, really bad. After some playing around I figured out the protocol for how the data is sent. The commands are bit and shifted out MSB first, the clock is idle low and the data is latched in on the high transition of the clock.

Arduino Tutorials The DS is a real time clock utilized by the arduino micro-controller to remember and to trigger time based events. It features a CR coin-cell backup battery pack, which will keep it powered for long periods of time when micro-controller power has failed by only powering the chip tasked with time keeping.
During this power failure, the red LED which would normally be illuminated will be off during this time. Due to the various settings the module can be deployed it has a temperature-compensating chip that varies the oscillation cycle to adjust for high heat and cold. From your Zip file, select RTClib. Next, you must desolder components seen in the red circle below.
The default configuration of the DS is to use the backup battery when not connected to main power and to use main power when its connected to it. Along with using main power, the DS diverts some of the power back into the coin cell battery to try and recharge it, which is a good idea in theory. Use a soldering iron to remove the components circled in red and you effectively mitigate your chances of having an exploding battery.
