Hi
You need 4 photo-resistor and two small plattes like "walls" (e.g. built with
lego). On your device you mount one platte horizontal and the other vertical.
The two small walls have to be mounted rectangular to your device in the
direction to the sun.
On each side of each little wall you put one photo-resistor.
As long your device is in position, all four photo-resistor are in the sunlight
and therefore have a low resistance. As soon the sun has moved (a mean the
earth). One or two photo-resistor are no longer in direct sunlight and their
resistance go up.
Meassure these 4 resistance with your HB and use two motors to move your device
back in the right position.
bye
Martin
