Hello everyone. I am trying to convert my analog motorcycle signal lights and temperature sensor to output for a neopixel stick (8 led).
I am a beginner, but I figured out more or less how to send info to the stick and wrote a dirty demo for it that can be seen at: - YouTube
This is what I'm trying to achieve: http://i.imgur.com/wUAMXMu.png
Now, I studied my motorcycles wiring diagram, and made a sort of wip sketch of the whole thing here:
All I know is that I need to step down those 12 volts to 5 or less, but I am painfully unaware of how to do that properly and safely, and then how to read the result in Arduino and act on it.
I won't even ask about the temperature sensor at this point because I don't even know what signal it is outputting, and if my schematic of it is correct.
Could anyone point me to a clean way to get all these voltages to Arduino's level in an efficient way and read them?
I think the ones grounded with green wire don't need to be keyed because they are interrupted on the positive by the key switch.
