Alternate Turn Signal - - outside the box

I am building a Pantera. I have adapted a universal steering from speedway with a quick release wheel. I have still to make the trim piece which meets the wheel so it looks narrow right now.

Obviously there are no turn signals. I am using a programmable circuit for the heater called the Arduino. The Microcontroller controls 8 servos to control the function of the heater box.

I am working on incorporating turn signals and flashers into the same circuit. I built a short steering section and built a rotary encoder for the end of the shaft. With a rotary encoder I am reading the position of the steering wheel.

I got the rotary encoder to reliably read the position of the column which was the hard part. I turn the wheel right or left and it knows how much and which direction.

With that info the Micro controller reads input from the turn momentary switch to turn on and off the flashers. With this kind of set up there is no "cam" for the column to deal with. This is nice because there is always a spot on the cam where you have to turn your wheel back to get it to arm. You won't have this here.

With the circuit controlling the turn signal, it also controls the flashers and such. I can add things like, if the turn signal is on for 5 min, turn it off.

I can also do things like, when the flashers are on, and I wish to make a left turn, flash 2x, left turn signal 2x, flash 2x, left turn signal 2x, etc.

I am using a marker light up front for the turn signal so it will be able to manage this as well as a marker light and a turn signal.
