Re: [ATM] Dark Sky Meter

I've been working on one also using a TSL237S Light to frequency sensor 
(the TSL230 wasn't sensitive enough) and a PICmicro 16F88 connected to 
seven segment LEDs (they dim as the sensor detects less light).  The 
intent was to eliminate the human factor and add consistency to the 
reading.  I'm still tuning it, but it pretty much works for reasonable low 
light.   I'm not a hardware guy so this has been a learning experience for 
me.

The PIC code is in CCS C.  Email me if you have any use for it or the HEX 
file or want more info about the circuit.  Keep in mind that it's a work 
in progress.
