It only takes a minute to sign up. Im trying to connect a MIDI input cable to an arduino. To do that, I need an optocoupler, that secures the internal circuits from damage.
I have a PC optocoupler by Sharp lying around, so I'd like to use it in the circuit. The problem is, that I'm not quite sure if this optocoupler can be used for this circuit. I think that the maximum ratings are acceptable but maybe I'm missing some details. However, there might be problems with the other parameters of this optocoupler.
The MIDI specification calls for a high-speed optocoupler. With the Arduino's Schmitt trigger inputs, and a portion of luck, you might actually be able to get the signal out, so you might as well try it. However, this is nothing I would recommend you rely on. If you don't want to buy a suitable optocoupler like the 6N, 6N, or H11L1, you could try to use additional circuitry to prevent the phototransistor from saturating and to amplify its signal:.
IMO it shall work without any problem. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered. Asked 4 years, 7 months ago.
