// OpenLight (GPL v3) + no commercial use without permission! Free to modify but you have to name me in your project.
// share alike / this is also for the 3D Printed parts, not only the arduino code. Thanks and enjoy it!
//
// I am sure this will be updated from time to time, so come back for the updates.
// The/a free programmable UniLight (Copyright by https://www.unilight.at/) and modifyable for your needs! Open Source.
// to realise Light schemes to your vehicle - plane - truck - crawler - boot - etc.
// it is based on Arduino (https://www.arduino.cc/) - in my case I use a Arduino Micro 5V
// to power it straight from the 5V Servo port of my Receiver. Just plug it in and the arduino
// is doing its job.
//
//
// How does it work:
// On the "PWMInput1" Pin (in my case D9) the PWM from the receiver is read
// with a following IF the position of your source / switch is detected and translated in
// a specific blink scheme / perma light if you want (but look for the heat if you are using high power LED).
//
// In the example:
// full low < 1200 uS = no light at all
// mid range >1200 <1600 = slow blinking
// high range >1600 = fast blinking
// /feel free to express yourself in building your own blink schemes by adjusting the timings.
//
// while the LED´s generating a lot of heat if the are turned on for long time, I only switch them on
// for 10 mS! That is enough to get the needed flash and stay cool, but feel free to modify it for your needs!
// In the example only LED1 Pin 3 is connected as output to a MosFET Board, but I already defined 4 / 5 also if you need them
// copy & paste the code and change the LED1 to LED2 / LED3.
//
// As I said, I use a 5V Arduino Micro, so I can connect it straight to a free RX channel for the PWM Signal + 5V to power
// the Arduino. Win win :)
// no special lybraries are needed, so it should be fine to use "almost" any Arduino you have laying around. Try it.
//
// watch in the serial monitor/plotter your RX input. If there is nothing detected, it can´t work.
// I had the case that with a cheap SERVO TESTER it was not working, but with a actuall RX it is always 100% working!
// So I looked with the oscilloscope on the PWM of the Servo tester and omg, that was distorted and no wonder it was not working.
// Keep that in mind, if you maybe test on the bench.
//
// UPDATE FOR WS2812 LEDs.
// Support for WS2812 LEDs implemented , with the need of 1 library. The Library you need to install is named: AdaFruit NeoPixel
// Without the library, you will receive an error message :)
// Have fun, playing with the "onewire" LEDs.
// As you see in the code, it is implemented in the "mid" position. Feel free to midify.
// now - let´s blink :)
