I'm pondering a project where:
What I'd like to do is:
I had a vague idea of having the combined voltage of the photodiodes get fed to a zener diode tuned to break down above 2.7 volts, and then have another zener diode that breaks down above 4.3 volts. Then use the voltage from the three points (before, middle, after) and run those through AND and NOT to produce a signal on either the "set" or "reset" for the latch.
Apologies in advance for any vagueness, incorrect terminology, or outright misunderstanding of why electricity doesn't work like water in a pipe
I guess it wouldn't hurt to mention that what I'm trying to build is a design for a RAICL[2] Block
Thanks in advance!
[1] where "illuminated" is seeing the expected amount of light, and the diode will be in an environment where it can only be exposed to a specific source
[2] Redundant Array of Inexpensive Conway's Life Blocks -- that is, blocks that can fit jigsaw style into an arbitrary number of tiled blocks where each has an LED in the center, and based on the eight photodiodes' input from their neighbors, will follow the rules of Conway's Life to either illuminate or die on a "next" cycle.
- there are a group of eight photodiodes, each tuned to emit one volt when "illuminated"[1]
- the output of these photodiodes is aggregated together to produce an output from one to eight volts
What I'd like to do is:
- send an output to a latch to set it when the voltage is greater than 2.7 volts and less than 4.3 volts
- send an output to reset that latch when the voltage is outside that range
