Midi clock to tap tempo would be a handy project for all the effect pedals that don't have a midi connection but have a tempo/exp input

[@NotesAndVolts]

Very cool idea!

[@TamiT]

Just a few weeks ago I realized I neede a midi pedal that also has midi controlled relays. So I started looking around for good recourses about how to use arduinos with midi, found your channel and have learned so much already, and now you release this one! About the exact subject I want to make myself! Thank you so much for sharing your knowledge with us, it is really appreciated.

[@NotesAndVolts]

Thank you so much! I'm glad it helped you.

Fantastic project Dave, this will allow me to control my guitar amps channels & effect status. Amazing

[@NotesAndVolts]

Thank you! That's a great application.

[@qiuzimorp]

I'm a new subscriber here. Please can you make a tutorial on how to control relays with midi note virtually using LoopMIDI? That would be really cool 😀

[@dexterslab_23]

Awesome project Dave!

[@NotesAndVolts]

Thank you Dexter!

[@DawlessHouseMusic]

This project is awesome.

[@NotesAndVolts]

Thank you!

[@pjtardiveau225]

Ok that's nice but you should prefer some Solid State relay shield... totaly silent, that's important when you play music, and more reliable in time.

[@donm1547]

Your vid is the only one that explains this application in FULL! THANK YOU, BROTHER

[@NotesAndVolts]

Glad it helped

[@jagtone]

Thanks, Dave, this could make for a really simple MIDI controlled 4-pedal pedalboard looper. I'm guessing PC codes ought to be useable too (for presets), with a bit of coding.

[@youpagan]

Found you in a search for a relay project - Brilliant tutorial - going have a go it. No idea what other things you have done but for me it was an obvious subscribe. I was wondering if it could be adapted to play midi files or basic sequences. EG press a key for a sequence of relay events with timed durations.. musically a primitive sequencer I guess

[@PCBWay]

Thx a ton for your sweet support, dave ❤

[@NotesAndVolts]

Thank you @PCBWay!

[@eross21]

so how would i wire this on the relay side of things? let say i want the relay it to control an outlet. and have a string of lights plugged into it that outlet so that every time a specific midi note plays. it lights up the string of lights.

[@gearscodeandfire]

This channel is such a level-up for me to watch, thank you!
Are you still taking requests?
An esp32 based midi receiver that can map midi inputs to different functions. I have six front yard walkway lights that shoot propane into the air running on the ESPNow library. I want to key them to diffent frequencies and button velocities to make them, uh, shoot burning propane into the air (i did a build vid on my channel).
Awesome channel!

[@TomboRectify]

13:47 I don't think that really matters...
But if you happend to respond, is it possible to add other functions to that code?
Perhaps with the outputs so that it wouldn't be controlling the relays but stepper motors with the 4-pin input type?
That would also require mapping a note for each of the MIDI commands.

[@DawlessHouseMusic]

I would like a 4 send/ return multi effects processor with LFOs. Delay, Reverb, Phase, Filter. Audio level inputs. I'm learning stuff and if you can do something like that, rock on.

[@NotesAndVolts]

Thank you, that would be an awesome project.

[@tubeDude48]

What is the Midi controlling? A controller for lights, or a Keyboard etc.

[@NotesAndVolts]

I'm not sure what the client is going to do with it, but it can switch anything up to AC-250V 10A.

[@spranceanaalexandru2127]

Nice project? it is difficult to change if you want to use midi usb instead of the traditional one, of course with an arduino compatible usb midi such as Arduino Due?

[@NotesAndVolts]

Should be easy with a USB compatible micro. You would just swap out the midi library commands with the equivalent USB Midi library commands.

[@spranceanaalexandru2127]

@@NotesAndVolts can you help me with this please?

[@artsplunge]

You could probably create a very simple "pre" circuit with a toggle that would go between "development" & "production" to prevent the situation where you could possibly be using 2 power sources and have that situation where there may be interference in downloading the code. I know - for the first time a legitimate constructive comment. Well,, I've been drinking heavily.

[@NotesAndVolts]

Thanks Arts! That's a very good idea

[@asbestbau]

can i power it with just my arduino if i just use one relay

[@asbestbau]

yeah works alright

[@allansimonsen6982]

I'm really not very good at programing Arduino thats why I asking You guys
Can you make it so that the relay will turn off again after 5 sek. (5000ms) using the delay function?
I will only use 1 relay so it dosn't matter that the arduino can't do anything else while it's controlling the relay
