![]() You can find other color values by using a color picker HTML tool. ![]() So I would write in my sketch: Īnd still get neon green, just not as intense. Now, if I wanted to vary how intense the green is then I could halve all the values. Where Green is 100% Red is 22% of Green Blue is about 7% of Green. It's important to know that to get color mixings you only need to change the % of colors that you are using. You can change the colors that are being shifted. If you change the # defined, you also must change the # of matrices that are present (the rows of curly braces). ![]() You can change the speed that you shift the LEDs by increasing MSSHIFT from the 250 to a higher number.Ĭhange the number of LEDs you are driving. This particular pattern runs to shift LEDs one at a time at a set interval (defined as MSShift) Now that you've got it to work, you should try and change the code around. Lay it down and identify the Data-IN side. Additionally, each manufacturer may end up using different pin outs for their PCB's and you want to make sure the segments all match exactly. (LEDs have variability and it's best to try and keep them as close as possible to each other). Finally, theres the call to pinMode() that initializes the pin as an output. Second, theres the pin variable which the functions use to determine which pin to use. First, of course, we have the dot() and dash() functions that do the actual blinking. All the sections look like they are part of the same batch. The sketch has a few different parts that well need to bring into our library. If you are using a strip from a previous project, you should check how well the pads are holding up. Sometimes pads will pull off or get weak after soldering to. All of the pads you need access to are there. The additional section was soldered on correctly in the right direction. This is very normal for sections to have been soldered in.ġ. Although these are rare, there are a few things you should check. Don't worry too much if you see soldered connections, this mean a section was added to your strip at some time (many times the manufacturer will add segments to make a full reel), but the strip should work the same. Incidentally, none of us have a DUE so we cant test. You will need to know how many LEDs you have for any code that you write. It is supported by the library and presumably runs at up to 24 MHz SPI speed with full-size shield. The strip should be one single piece with 15 LEDs (it's usually 30 LEDs per meter).
