I am trying to monitor the status of another system (a rather complicated battery charger in this case) using my Teensy 3.1. The system has about 10 LED's (green, yellow or red) that indicate various states. The system is mounted in such a way that I can't see the LED's while it's operating. I was thinking of using a photoresistor and just filtering for the red (I only care about the red) but this just seems a little too simple. I am thinking of it more or less like a color detector, I'm just not emitting the colors. while operating, there isn't any ambient light to mess things up.
any thoughts as to whether this is a reliable approach or if there is a better approach would be appreciated.
The whole thing is complicated by the fact that I don't have access to the equipment (until I install it) combined with it's remote location means that I have to have the hardware right before I go install it. Software I can change on site.
Thanks, Mike
