LDR Array for Solar Tracker

thingiverse

This is a simple setup for a solar tracker I am creating. As such, it only includes a dummy light-dependent resistor I uploaded to Thingiverse yesterday, located at http://www.thingiverse.com/thing:858043. Analogue pin A0 connects pairs 1 & 2 together, and analogue pin A1 connects pairs 3 & 4. Meanwhile, test pin 9 can be raised to HIGH for testing purposes - which may or may not save power! (That remains to be seen.) Here's how I have the components connected: * Ground - Light-dependent resistor 1 - A0 - Light-dependent resistor 2 - positive (+ve) on Pin 9 * Ground - Light-dependent resistor 3 - A1 - Light-dependent resistor 4 - +ve on Pin 9 There are two pairs of light-dependent resistors, each consisting of a single pair with one side connected to ground and the other to a common voltage. Both of these pairs connect their other sides together at analogue pins A0 and A1 respectively. The light-dependent resistor layout I used was: * Set 1: Light-dependent resistor 1 is directly next to set number four * Set three, in turn, lies right beside light-dependent resistor 2 Set 1 consists of two components connected together; specifically sets three and four. When both are set 4 the entire connection will be grounded, as it were. Ground pins have a strong relationship with one another and thus when combined can result in numerous unique effects, so keep that in mind. Each is vital in understanding just how a solar tracker functions overall. Choice table options are divided up like this:
