I want to garden this summer. More specifically I want to have a container garden on the porch of my apartment to provide a few of the spices and vegetables we regularly cook with and make the porch more enjoyable. I had one little problem though. I’m not really sure how much sun my porch gets because I’m hardly ever at my house for an entire day. So I decided to definitively measure it using an Arduino and an Adafruit datalogger shield.
First step was to assemble the data logger.
Then I downloaded code libraries and worked through tutorials from Adafruit to get the datalogger’s clock programmed and to teach myself how to write to the SD card. You can’t find a company more helpful and supportive than Adafruit when it comes to electronics!
Lucky for me, one of the tutorials is fairly close to what I want to do. So all I have to do was modify some code to work with my project, and redesign the circuit to include the extra photoresistors I’ll be using instead of the temperature sensor. I’ll cover how I did that, as well as the program I wrote to graph the data my device collected in Part 2.
