just make sure this value matches the location your strip is plugged in.įifth is the order of our colors. 100-1000pcs pack micro apa102 2020 led chip smart smd rgb led light beads apa102 2020 256 8a led matrix program software control. In our hookup diagram we have it connected to PIN 2 but it could just as easily be PIN 3, 4 or 5….
This is where we are plugging the data wire into the Arduino. Next we tell the Arduino what PIN we are using. The FastLED library can be used to control many different types so we have to specify WS2812 (even though technically we are using WS2812b). Third we have to tell the FastLED library what type of strip/lights we are using. If you want use more change this number accordingly. For this example we are just using 2 LEDs. Second we have to let the Arduino know how many LEDs we plan on using.

The FastLED library knows how to convert our decimal numbers into the binary the Arduino needs. This allows the Arduino to understand the next few commands we are going to use. The first thing we do is include the FastLED library. Lets take a look at what each of them are doing. The Arduino goes line by line and executes each command once. Sign test character string definition LED signs will show scrolling text similar to that set out below, followed by a series of horizontal and vertical line test patterns: Example: OLED v1.15 (X1.15) 0 144x19 C3D00 P65/100 OLED v1.15 the signs base software type and version (X1.

The first section of code runs the setup. You can instruct your sign to play either a selected few messages or all of them in. You can usually go up to 99 messages on the electronic sign. Add more messages using ‘02’, ‘03’, ‘04’, and so on to save your messages. We also need to connect our Arduino to the computer and give it a connect to the same ground as the LEDs. The basics of programming a simple LED sign are as follows: Use ‘01’ as the program name of your fist message.
The power/ground to the supply and data to the Arduino. Our LED strip has 3 inputs we need to connect.

For this we’ll just grab a 5V power brick and we’re good to go.ĭC Barrel Connector (included with Power Supply) Lastly we need a way to power everything. Don’t worry, even if you have no programming experience we’ll work through the basics in no time. Because our LEDs have so much customizability, we need something to tell them what colors to be and when. Alright, so what do we absolutely need to get started? We’ll need the LED strip, but we also need something to control them.
