This is such a brilliant project! I tried so many versions of the Switch-Fightstick library, but for whatever reason, yours was the only one that ended up working on my Arduino. You saved me so much hard work and headache, thank you for sharing it!!

Thank you sooooo soooo much. After a very long research i have found finally somthing that works. You are the best :)

that's cool!! i'll definately try this out sometime soon!

Your issue with plugging the arduino into the breadboard might not be so much the tightness, but rather, the alignment of the pin headers. I have a cheap old breadboard which I use for sodering headers. Don't use a good one, because the heat from soldering will ruin it. Basically, I insert all the headers, then put the board on and solder everything. Not only does it result in perfectly aligned pin headers, it also prevents burned fingers.

To your question about why it worked without connecting ground and +5V, I have a theory. All voltage is a relative measure, so in order for anything to communicate it has to have a shared reference point. This is what we call ground or 0V, but really it's just 0 volts because we've defined it that way (as our reference). So you should always connect ground. The pro micro is powered by the +5V coming from the USB (from the Switch). The chip on that USB serial board needs power too. It could be getting that power from the +5V that you're hooking up on that external pin so that it is also powered by the USB connected to the pro micro, but I think it is more likely that it powers itself from the +5V on its USB (coming from your PC). If the latter is the case as I suspect, then that 5V pin is probably actually meant as an output so that you could power whatever you connect it to off of the same USB. But in this case you're connecting it to the pro micro which already has power so not only don't you have to connected 5V to each other, it is possible not a great idea to. Try disconnecting the 5V (but leave the ground connected) and let me know if that still works. If it does, it probably always will and be a better way to set it up. But how did it work that one time when you didn't connect the ground either? It is possible that the two USBs already had a shared ground. Like if you plugged both USB cables into the same PC, that'd probably work.

Fantastic project and one that I was excited enough to try and assemble. When attempting to flash however, I keep getting a 'programmer is not responding' error. I've tried everything I could find searching to no avail, about to just give up completely. But still, a neat project and respect for thinking outside the box for how to shiny hunt!

funfact: Vcc is actually a remnant of the labels given to parts of a transistor in physics papers and in eventually in textbooks. I think it stands for collector voltage (transistor has 3 parts, the output is called collector)

23:48 Maybe you could use this to have the Twitch chat play Super Mario Maker 2; That would be an excellent idea!

Ben Eater collab when :0

In your scripts folder you have _clock.py, engine.py, etc. Can you provide some descriptions on what these are for/do?

Very new to this, but I'm curious if it's possible to have a prewritten scripts on an Arduino and just hook it into the switch by itself. Do you need to have that USB to Serial bridge to the computer to make this system functional? Is it the computer acting as the controller, or the microcontroller itself?

could you explain a little more about the type of the wire that you are using? I kind of don't know what kind of wire that is.

I've been trying to replicate the seen on the video but when i try to flash it on the Pro Micro it gives me this message "avrdude: butterfly_recv(): programmer is not responding". I tried everything and nothing seems to work, I'm using Kali on a VM. Sorry for the inconvenience.

Hello Hello, I seem to be having an issue where the pro micro isn't entering programming mode. It's the same one you have linked in the readme, I have tried attaching a button and using a headphone jack. But windows never makes the noise and the terminal repeatedly gives me: avrdude ser_send() OS error: unable to write: Resource temporarily unavailable avrdude butterfly_vfy_cmd_sent() error: programmer did not respond to command: leave prog mode and then getting stuck on: avrdude butterfly_vfy_cmd_sent() error: programmer did not respond to command: exit bootloader Is this anything you might have words of wisdom for?

Is this code able to be used to build your own controller and then sell? I have a few ideas but I'm confused on the license. I'd like to start making my own but I'm not sure if using this code is viable or if I'd have to go about creating my own code for my own controller if I wanted to sell it.

This is a Great Project, I have a question, Could this be used to Take an actual Switch Controller or GameCube Controller and upon certain inputs, run custom macros?

microchips don't break that easily :p at least not without some smoke (I've had some work even after smoking!)

you are quite amazing

I have managed to wire everything and setup my board and etc, I am on windows so stupid question but what do I do for "sudo apt install avrdude gcc-avr avr-libc dfu-programmer" on windows? Im trying to follow along and try the regi reset approach. Essentially where would I plug in all those commands at 12:31

Any chance you’re going to work on anything for brilliant diamond/shining pearl?! I’d love help with restarting for my shiny starter but can’t find code anywhere!

Would this project with a raspberry pi 400?

This is old but I had a project of using CV to shiny reset for a shiny afk. (Still new to python) My plan is to have a true false or something like that with the two images of the Pokemon. If it's the shiny then to stop resetting and if it's not continue running the code. What is your opinion on this.

This is an amazing project. I have one question tho. Is there a way to hold a button down without giving a time limit. The reason I’m asking this is because I want to get my Xbox controller to work with the switch so I wouldn’t know how long to hold the button down for.

Say I want to write an AI that does the aiming for me in a shooting game, can I seamlessly switch between chip control and actual control?

Hi, i don't know if you're still responding questions, but i don't seem to have this working. I finally got to the final part of this video (which is finally plugging in the arduino usb into the dock) but the console doesn't seem to pick up arduino, and after i try to code in the press A code. i either get a "ModuleNotFoundError: No module named 'scripts.switch'" error if i don't have the scripts folder in the nintendo switch or a "SyntaxError: invalid syntax" error when i do. I doubled checked and i have everything done correctly just before this step, so i don't where did i go wrong

you did the project very good!!! i really appreciate it , but i have one bugs when working on your project : that it appears Connecting to programmer: . avrdude: butterfly_recv(): programmer is not responding Found programmer: Id = "1023 �"; type = Software Version = 1.0; Hardware Version = 2.3 avrdude: error: buffered memory access not supported. Maybe it isn't a butterfly/AVR109 but a AVR910 device? avrdude: initialization failed, rc=-1 Double check connections and try again, or use -F to override this check. avrdude: error: programmer did not respond to command: leave prog mode avrdude: error: programmer did not respond to command: exit bootloader i hope you can help me to take it look, really thanks

Would it be possible to use an arduino uno with a atmega328p instead? Because when i try to make its firmware. It just spits out a bunch of errors

Been trying to work this out, but I've been getting an error when trying to program the Arduino. I get the error 'avrdude: ser_open(): can't open device "/dev/ttyACM0": no such file or directory'. I've tried googling around for a solution but haven't been able to find anything. I'm not familiar with Arduinos or virtual machines, so I was wondering if you knew what might be causing the issue?

I know the chances of you responding to this is low since the video is old, but do you think it’s possible to use two bluetooth chips to control two switches at the same time with just one input?

is there a way to read controlers/ring fit movment to translate it using python as a new output for other games?

Can this work on an Arduino Uno?

when i try to run make, it tells me "grep: /usr/share/arduino/hardware/arduino/avr/boards.txt: No such file or directory" How do i fix this?

Anthony once again I have returned, The VM approach would not work for the life of me, I figured how to use windows instead however I require the direct location of the hex file, I tried to find it in the github but could not find it.

Isn't there a way to just run a program on your computer which connects directly to your switch and sends the controller inputs?

O_O @8:30 lol (reclick for optimal effect. lol okay im being immature :P @8:35 )

is it possible to control it using buttons connected to the arduino board itself. Cant seem to find an answer to that

NOOOOOOOO the push pin was painful.

Stupid question 🙋‍♂️: if I connect various microcontrollers to the same computer can I control different Nintendo switch(s)
