Circuit Board Instructions
We need to build a small, circuit board to interface between the Raspberry Pi. The main reason for this is so we can use the photoresistor to deterime if it is daytime or night time. Since the photoresistor is analog, and the Raspberry Pi does not have an analog interface, we need to use a DAC to convert the analog value from the photoresistor to a digital signal that the Pi and read.
The easiest way to convey what we must build is to show a circuit diagram. Please look at the diagram below and assemble the circuit board according the the diagram.
Note: Please terminate the wires plugging into the Raspberry Pi the Dupont Terminal Connectors.
The completed version should look like this:
