My electronic turn signal project is wrapping up. I put in a steering column with a removable wheel and no provisions for turn signals.
I made an encoder which fits down on the column. I got the while circuit working pretty well. This allows me to do anything for column trim.
It has opti-isolators to isolate the 12v. The circuit is quite programmable. This has allowed me to:
Toggle switch for turn signal (push button on designer board).
Turns off with opposite movement of steering wheel OR cancel by selecting other turn switch direction.
Automatic cancel after 5 min (or what ever I program).
Front turn signals are also marker lights. Turn on lights, front marker comes on. Hit turn signal and flashes.....OR.....I have also played with a PWM to toggle fronts with 2 different brightness. Full, half,full, half etc.
Flasher reference does flashers but also works with lights AND Turn Signals.
With turn signal and flasher, it flashes all 4 2x then flash the turn lamps 2x then repeats.
All is done internal to the circuit; no relays or external devices.
This is ALSO the circuit which controls 5 servos for the heater distribution system.
