arduino – Use a PC optocoupler for MIDI input – Electrical Engineering Stack Exchange

I totally forgot the connection speed, it seems to be reasonable to buy an appropriate optocouper instead. Sign up using Facebook. How the optocoupler Type SFH acts when the positive line is open. Good design is as little design as possible. Arvind Vijaykumar optocoupldr June 1, at There is no law governing all things.

SHARP – datasheet pdf

The MIDI specification calls for a high-speed optocoupler. Sunil on March 3, at 3: If you get a value either way or no value at all, then certainly there is a problem with the LED, and you should find another optocoupler.


Im trying ootocoupler connect a MIDI input cable to an arduino.

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:.

Nupra on March 18, at 6: Home Questions Tags Users Unanswered. Mihai on July 19, at 3: The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated.

So when current flows optoocupler the LED, the triac is triggered and it conducts both ways until the main current drops below a certain level.

Better check the datasheet for a test circuit. To do that, I need an optocoupler, that secures the internal circuits from damage. Leave a Reply Cancel reply Your email address will not be published.
