Need advice on Fastled and Arduino Mega 2560

Other Hardware LEDs and Multiplexing
1

Hello everyone,

Forgive me if I posted this in the wrong area. please move it to proper area if needed. Thanks

Okay here we go. I have a 2003 Honda VT1100 Motorcycle. I want to use my Arduino Mega 2560 and use FastLed to creat my Led lights for my Turn Signals, Break and running lights I also want to be able to have it change colors and patterns when I am not in motion.

I purchased the following led's I believe they should be compatible.

12V Flexible SMD 5050 RGB LED Strip Lights, LED Tape, Multi-Colors, 300 LEDs, Non-Waterproof, Light Strips, Color Changing, Pack of 16.4ft/5m Strips

https://www.amazon.com/gp/product/B006LW2NJM/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

I would like to run about 120 lights. question is can I power the lights using the motorcycle battery. I have 7 sections

  1. front Left turn signal/ Running Lights (color) yellow
  2. Front Right Turn Signal/ Running Lights (color) yellow
  3. Rear Left turn signal/ Running lights (color ) yellow
    4 Rear Right turn signal/ Runing lights (color) yellow
  4. Taillights / Brake Light
  5. Gas tank lights
  6. Undercarage lights.

Thos are the areas I want to light up I want to have all of them capable of multi color and movement execpt when I am driving. I hope that someone can help me with an idea of how to wire this and program it thank you very much in advanced.

Check your local/federal rules, many of what you want to change color are specified by law to be a specific color such as red. Before you spend a lot of time read the following:
There is many good app notes such as AN2689 by ST on automotive electronics. reading it will help you a lot.

Right the Red and blue can only be used stationary unless it is the brake light or tail lights. the ground affects can be any other color.

You have 100 LEDS-per-meter. BUT the chip was not shown. A WS2812 will be individually addressed LEDs. A WS2811 will be sets-of-3 addressed LEDs. You will want IP65 (protection level). The IP67 are good if uncut, but you have to deal with sealing the rubber housing if you cut it. Cutting the strand and wire-splicing the sections I find difficult to make a "permanent" connection. The solder pads are strong, but not as strong to be bumped by a foot. Once you get the pieces connected, the program will be a matter of creating sections (zones) that you will give commands to create effects.

I think you will find none of these Amazon products are as bright as your current lights. You can see real turn signals for hundreds of feet in full daylight. The WS2812/11 are not that bright. Night time they might look cool... but you will never get the same "yellow" as a stock light.

Do not make this permanent. The LEDs will burn out in a year or two if left in the elements.

Thank you for your reply, I looked at these leds and they are 4 pin 1 positive 1 red 1 green 1 blue. I don't believe these are programmable as I do not see a data direction I think I will need to order another set of lights.

All the LEDs on one data pin will be a single color. If you cut the long string (at the solder pads)into small strings, you can configure different data pins to make different colors.
