This is the first time I'm drawing a schematic, thus why this question seeks to get clarification from you experienced engineers :-)
A little background information:
I'm trying to draw a circuit for an oximeter "breakout board" for my Arduino. The circuit contains respectively two 860nm LEDs and two 940nm LEDs. (I'm not sure which LEDs to buy yet, hence why the resistors are not given any values)
To measure irregularities in the emitted light from the diodes, I bought the FDS100 photodiode from Thorlabs - Which also is the component that confuse me upon drawing the schematic.
I'm planning to supply the board with 5V from my Arduino, and from the datasheet, it seems as if the FDS100 can handle much more - hence why I haven't added any resistors. The FDS100 has 3 legs, where one of them is a case(??) - I've read in another post, that it is good practice to ground the case, but not necessary. (I have done it anyway)
Furthermore, I understand that the FDS100 is "reverse biased", meaning that current flows in the opposite direction, hence why the analog port in my Arduino should be wired to the cathode of the FDS100, in order to be able to measure how much light that the FDS100 picks up.
Have I done this correctly, or am I missing some important details, i.e. resistors and other components concerning the FDS100?
