This post has developed a lot since this intro so it would probably be better for you to start at the bottom. I want to edit it and make it more concise.
The input for this project will be the analog voltage from a voltage divider. This voltage will vary because of the variable resistor, the photoresistors. There will be 16 of these resistors.
I would like to read out only two states. Either side of some voltage value threshold. What this is value is exactly has to do with my application. Basically the photoresistor will be under a cover, mounted on a faux garlic head and I want to know when the faux peel is removed:
I would like to illuminate one LED per bulb peeled (LDR). It does not matter which LED goes with what.
I would like to use the MAX7219 dot matrix module microcontroller. I have the unassembled module so i wont use the led tha com with it: I read about this module on the arduino playground and i will use this schematic for a basis of wiring:
in Conclusion I want to write a program that basically does like the topic says:
has an input from multiple LDRs then lights up 1 LED per LDR to indicate light or dark.
Please let me know if you would care for more details. Any advice would be awesome.
