I am currently working on a project for school. This project is to create turn signals that can go on the rear end of a bicycle, as well as having a thin light panel for nighttime riding. I would like the turn signals to have the following critera:
Two LED lights on one panel, with each "light" being an arrow that faces the opposite direction (just like a normal turn signal on a car)
Each light (right and left arrows) being controlled by their own activation mechanisms. Basically, one button to click that will wirelessly turn on the right LED blinker signal, and one button to turn on the left. These buttons would be separate from each other (not located on the same panel).
Pressing both buttons at the same time will make the LED arrows blink in unison (just like hazard lights on a car).
Holding each button for two seconds at the same time will make the LED arrows blink in unison even faster (like emergency lights).
A thin light panel that could be activated independent of the turn signals (again, wirelessly) so that the user can be seen by others at nighttime without activating their turn signals.
I read that something similar to this could be achieved using two HC-05 modules, with one being a "master" and the other a "slave". What this means is pressing a button on one of the modules will light up an LED on the other.
If someone could point me in what direction of how to get started with this and what specific materials would be best suited for this application it would be much appreciated!
