Hi I just started to do an exam project where I have to do some Arduino coding and I do not know where to find the code info I need. I have to use an OPB705, which is an infrared light sensor, and I want it to connect to Analog in pin A0 and I want the Arduino to read the Volt frequency value it reads so I can do a lot of if and else statements for it its LOW or High. But I dunno even how to start up. Please help me.
For a start
a) Read the datasheet of the OPB705
b) Learn how to code (or at least look at the examples)
c) Chop your projects into little pieces 
Thank you for the help.
