Ok, shameless newbie question time again.
I need DIN MIDI Input for a project (no MIDI Out needed), but I'm focussing mostly on the software side; the electronics is way out of my comfort zone. I'm trying to interpret the schematics but I have no idea how to translate that into my breadboard setup:
Q1: BoM...
I assume I need:
- PC900 Optocoupler
- 270 Ohm resistor
- 220 Ohm resistor
- 0.1uF capacitor
- anything else?
Q2: How do I create the 'loop' (?) between pins 1 and 2 of the Optocoupler? What does that look like in real life?
Q3: What is that bit of circuit coming out of pin 6 of the PC900? Is that a fork going into both Ground and +3.3 V?
