How To Turn An Arduino Into A USB Keyboard Or Mouse! | ATMega32U4

Рік тому

Just a quick video showing you the possibilities of the venerable ATMega32U4 - found in the Arduino Pro Micro, Leonardo and the relevant clones.
Check out Sparkfun's guide here, but please remember to include the Keyboard.h and Mouse.h libraries:

So simple! This looks like the start of a project for my Year 9 class. A handful of mechanical keyboard switches and some 3D printing could make a cool little macro pad. Thanks for the video.

@TheJcrist Рік тому

This is not only a keyboard but also any imaginable HID device, including UPS and 3D joystick.

@Mulakulu Місяць тому

This is awesome. Gonna use some parallel in to serial out chips to get many many inputs and make a number pad. I do not like the decision of adding the 500ms delay there though, due to not being able to press any buttons for 500ms. I think I'll just not have a hold function, and rather only send inputs when they are pulled high, and ignore that button until it's pulled low again

I had one of these for some time, with 12 button keyboard that uses only one analog pin, worked great, but those buttons were a bit noisy (12mm tact switches) and a bit bulky. So my next step was to make this thinner and silent. So I used one of these MPR121 12 touch pad boards, works like a charm, and it's really thin compared to my previous one

Could you turn it into a USB gamepad? A driving simulator controller would be a good project. Or RC model controller, reading servo PWM from an rc receiver, and sending this as a gamepad to a pc

I was looking for how to create a combined USB mouse and keyboard using an ATmega32U4 (Arduino Micro), but had read things implying that in order to combine two devices in one micrcontroller, you had to also implement a USB Composite device. And of course, most example programs only do mouse or keyboard, but not both. However, clearly this is not the case, since your example does exactly this! Maybe it's because they're both HID class devices? Whatever, now I know how to do what I need to do. Thanks!

But what I'm seeing from this code is that you cannot hold down a key. I could be wrong but if I wanted to walk using WASD I probably couldn't. I bought a metal DDR pad and the control box isn't working so i wanted to make my own JoyToKey after seeing how the pad worked.

@xsm5525 10 місяців тому

I have two questions, (the 2nd one maybe being a bit weird) 1, is it possible to send things like the Function keys (F1-F12 etc) and the left up down right arrow keys? 2. is it possible to have 2 x arduino 32u4's on one board, and have all 5 microswitches (like your own setup here) Y-lead off to both arduino 32u4's? I want to control 2 PC's at the exact same time (don't ask!)

@romeolz 10 місяців тому

i don't see anything preventing question #2 from working, u just gotta steal the signal going from the buttons to arduino #1 and connect it to the pins of arduino #2 (NOTE: i am an electronics and arduino noob, please keep that in mind)

@adriansfx 7 місяців тому

as for #1 you can, a lot of the custom keyboards out there are based on this little board, and as a matter of fact you can even send up to F24 even tho traditional keebs go just up to F12

@williamfraser 2 місяці тому

If you had eight buttons, could it combine the inputs and decode the "binary" string? For example, pressing buttons two and eight (counting from left) gives 01000001 and translates to "A".

Or you could use a single button, and make the user enter the characters in Morse code.

If you are going to plug it into usb, best to use the 5v version, simplifies a lot of stuff

@evdokimovm 2 місяці тому

That's the kind of "firmware", not the HID driver, am I right? I mean, when someone has soldered a custom keyboard, let's say, using an Arduino Nano, there is already a universal HID driver in the OS, but to make the output of the buttons correspond to symbols, you need to write a kind of "firmware", as shown in the video?

@CobraFat2000 3 місяці тому

I think you can probably use the same one as in video, but you'd need to explore making a grid- like with 12 digital inputs - wire them 6 horizontal and 6 vertical and check against pairs of pulled pins for inputs and you'd have 36 - maybe even 4x4x4 for 64 or 3x3x3x3 is a possibility for a full blown 81 inputs, but it will probably limit how many keys can be pressed at the same time - depends on application of the product you're working on.

@khefer1980 7 місяців тому

@FPChris 3 місяці тому

Can you send Ctrl+Key or Middle Mouse Button + Key?

@BrightBlueJim 2 місяці тому

Yes! Since there are functions to call for all keyboard and mouse activities, you can certainly send codes that combine mouse and keyboard actions. The SparkFun tutorial that he based this project on (see the link in the description) gives more information about things like separate press and key actions for the keyboard, which lets you simulate holding down the Ctrl key and clicking the mouse center button, then releasing the Ctrl key.

@vanchien5874 Рік тому

Hi, does it work for only windows? I want to simulate a mouse using this in linux. Is it possible?

@BrightBlueJim 2 місяці тому

Since Human Interface Device (HID) class devices are generic, they should work equally well in Windows, MacOS, or Linux. These all use the same standards, although some keys are labeled differently on Macs. There's nothing Windows-specific in this project.

@bluemuffin6160 10 місяців тому

How is this when compared to using QMK?

@BrightBlueJim 2 місяці тому

QMK probably started out as a project much like this. QMK is much more sophisticated in how it lets you define how every key behaves, but when it's running, it's doing very much the same thing.

@hoople212 Рік тому

@_BangDroid_ 9 місяців тому

Depends on what program you want to launch. Some applications can be opened using the Application Launch keycodes as part of the USB HID standard, these include Web browser, calculator, email client. Unfortunately the library used here doesn't support the full USB HID standard which means media keys and application launch keys are not possible. You could set the keys to be something obscure like F13 - F24 and use AutoHotHey to detect and run various commands, like opening an application. Otherwise, use a different library which does have full functionality, like NicoHood's HID project.

@doougle Рік тому

That's neat. If you knew a twitch streamer you could probably make a little device to fire commands and macros. verowaThink It seems like you could also fashion a customized game controller if the latency isn't bad.
