Re: Is debouncing needed for very simple circuot?
The signal source consists of the RC circuit's R1, R2, and C, connected right to the 4060 IC. And the output, also simple, a blinking LED, at a selectable rate from <4Hz to 40 Hz.
Maybe there is no bouncing? But only confusion due instead to the vast collection of stray electrons in my bread board, plus my bizarre miscalculation of units in the formula 1/2.3*Rt*Ct, where I used Ohms and Farads, not Kilo-Oms and mF!
I may be closer to version 2.0 than I thought. Would a similar arrangement using a microcontroller, i.e. one brief s.w. routine per frequency (<4, 4, 10 and 40 Hz, with one set of LEDs each) also be bounce free?
The goal is quite simple - to use lights flashing at these frequency to enhance brain wave synchrony, to relax (< 10 Hz, for memory (10) and for gamma-band synchrony enhancement (40 Hz - google "Picower institute 40 Hz therapy")
