Beginner question on datasheets basically.
I have this part, and am working from a tutorial for the code here, but am unsure exactly how to wire up the circuit and what risk I might be at for destroying it if I make a mistake. In the tutorial, the author doesn't give a circuit diagram, and merely says "All you need to do is supply a resistor (I used 200 Ohms, with a 3.3V supply) to the power line, GND it, then connect the data line to one of your digital pins (I used pin #2)".
However, the datasheet shows an example circuit with a 100 Ohm resistor connected to Vs along with a 4.7 micro Farad capacitor connected between Vs and GND. I'm guessing that I should connect Vs to the 3.3V output on the Arduino and use a 200 Ohm resistor, but do I need a capacitor?
If I wanted to connect it to the Arduino 5V output, how would this answer change?
Also, for pedagogical purposes, what information from the data sheet would help me answer these questions?
