H11L1 opto isolator does not pass signal to Arduino correctly Ask Question. Just doubting if the MIDI functionality will work since it will be functionally similar as now: As soon as you start using SoftwareSerial for a test, you are actually testing the SoftwareSerial itself.

What solved the problem was to use TWO opto-isolators. R2 and R3 form a voltage divider that prevents a proper high voltage; you datazheet to connect the LED to 5V as shown in Transistor’s answer.
Instead of the usual taking then listening in turn.
Fairchild adds an “M” suffix to optocouplers in a white package which has properties different from those of black packages.
Find which fixed pins are for RX and Daatasheet pjrc.
Update New sketch not having the duplex problem: So they write sketches which expect to talk in turn. Jun 25 ’17 at What you need is figure 6. Sign up using Email and Password.
I am not sure how the Arduino serial libraries are datasheer. That is an absolute maximum value, check page 2 for actual supply current values or figure 6. For MIDI, the differences between the clones do not matter. Also, if I need to get them from an online webshop from the Netherlands, euro shipping cost is added, making like 10 pieces of H11L1 cost even more.

I like how Transistor cleaned up your circuit. To be honest, I have a Mega, but I don’t ‘dare’ to use it, since that one is now on a breadboard circuit that I’m for sure knows it works and by disassembling it, I’m afraid I don’t have any working solution. Take a look at “Serial. Jun 26 ’17 at 6: Post as a guest Name.
Note, different Arduinos can use different processors with different internal hardware. This gives time for competing answers to be posted, and there are many better answerers on here than me.

I will try with higher baudrates It will be these differences in chips which may turn out to make your high level code work differently better in some cases. Some have more hardware buffering which off loads the burden of serial timing from the software.
The open-collector output will pull it down when turned on giving almost 5 V across the R3 – D1 combination. So when I’m off sending data I will not miss any data being sent to me.
