Here is the first working prototype of our eBookmark. The eBookmark will keep track of where on the page a reader leaves off in an actual analog book. This is just a proof of concept and now that the code is running we will finish the actual art piece. It is purely intended as an art piece and not a product idea.
Details: It is breadboarded with a teensy 2.0 AVR microcontroller board. The code is written in straight C, not arduino code. LEDs are hooked up directly to the port pins configured open collector and with 1k resistors on each. The internal ADC is reading control voltage generated by a resistive touch strip.
