simple tracker
« on: June 23, 2013, 10:01:32 AM »
Hi all,
I am looking for a simple method that would use sensors as inputs to track.
if one were to put a pair of light sensors on one window, and the arduino were to monitor those....
then as one got bright, it would cause the program to re-adjust the array.

My other request is about interfacing with cheap stepper drivers.  I found that they are being used, but did not find how you deal with them being powered.

Hi Dave,

I don't know of anyone on this forum who is using sensors for tracking the sun. The method we tend to use here is to just calculate the position of the sun and then move the machine exactly where it needs to be. There might be someone around that will chime in though.

I know I've seen tons of different projects scattered around the web that use light sensors. I'm sure a quick web search will turn up something. I've never really looked myself though. I imagine that if you are using light sensors, then you could probably get away with using DC motors which are much simpler to control. Like I said though, I'm not familiar with using light sensors to track the sun.
