You might have wanted to improve your workflow on your computer if so you might have looked at getting some sort of secondary keyboard, maybe a Streamdeck to automate some of those more repetitive tasks on your computer, but a product like the Streamdeck is 150 dollars on amazon (At the time of writing this). It is pretty straight forward to setup, but if you need more instructions or guidance, I would recommend checking out the, You then will want to grab the code for this project from. The Keypad Matrix plugs directly into the 8 GPIO on the bottom right of the Pro Micro, the ones labaled GPIO2 - GPIO 9. A macro keypad can be used to perform certain actions or functions on your computer and can be really useful with certain applications, such as video editors or games. A good use case for this might be a custom quick chat keyboard for games. If one of the column pins is high, you can tell which button was pressed as you now know the column row that was pressed. you can also press a key to type out a password account, and so on. It is pretty straight forward to setup, but if you need more instructions or guidance, I would recommend checking out the Arduino Class by Becky Stern. from $125.00 Sold Out [GB] D65 mechanical keyboard kit. A scripting language for creating powerful macros. Adafruit did an interesting breakdownon stream, but it’s essentially a mini computer using an Atmel ARM926EJ-S driving a 480×272 resolution LCD. And that's it, didn't I tell you this was simple! It only uses two components! It doesn't really matter what is in here once you react to the button press appropriately (more about this below)The next thing we have is the pin definition for the rows and columns, these are already set up correctly for the wiring that we did earlier.And finally there is the constructor where we initialize the keypad library with all the config. I modified their ideas and code to work for my liking. Take care not to change anything else on the line. I will be taking you through what you need, how to assemble it, how to program it, and how to improve it or make it your ow… A technique for drastically reducing the pins required by a matrix keypad is described. A lot of applications have hot keys for quickly performing actions, but sometimes it's hard to remember the button combination of each command, but that is where a macro keypad comes in. Let me follow you through. Share it with us! It takes in one parameter as a key, by default this is f1-f12 and then a, b, c and d.This method basically emulates holding down the following buttons. If your keypad had more or less rows or columns you would change it here.The "keys" array lets the library know what character it should return to you when a button is pressed. Step 2: Get You Keyboard ID. The 4 row pins are set as output and the 4 column pins are set as inputs.The Arduino will cycle through the row pins one by one, setting each one to be high, while the other rows are low. Step 6: [Optional] Explanition of the Code, My main use case for this device is to use it with hotkeys in OBS (. SendMacroCommand is the the method that all the options call. (Line 41 - 43), The next thing you can see is that if I press "q" on my keyboard Alt will be pressed down then F4 will be pressed then Alt will be released. In the first image you will see the configuration of the keypad library. F24 is a key in windows that is not on your keyboard. This is to tell LuaMacros what keyboard to listen for. Click install. We just need to configure the Arduino IDE for the correct board and port. I want to give full credit to Tom Scott and TaranVH. Super 16 Macro Pad. DIY Stream Deck (Open Source Macro Keyboard with LCD Buttons) A programmable macro keyboard is one of the best tools a streamer can have! You have a fully functioning macro keypad at this stage so If you don't care how the code works, skip this step. Don't let the coding scare you. These buttons will not be released til we specifically say for it to. This is like taking your finger hold down Alt then press f4 and then release Alt.This key combo will close any active window in Windows, You can keep adding macros like this by continuing the pattern. The buttons on top allow the LCD to shine through for the backlight icons, and push down on a touch matrix to trigger button presses. So if your matrix had the letters of the alphabet instead of numbers you could change it here to match. , its a software mainly used by streamers, but useful for capturing any video on your PC). Can achieve a key copy and paste such as a combination of keys(for example:ctrl+c/Q+W+E). To add a new macro write, You can also use keys on the Numpad by writing. The next button you press will be the command associated with this action, so use your macro keypad to press whatever button you want to control this action. The command for typing out a message is either keyboard.print. Macro keypads can be a really useful productivity tool, and I challenge you to find a simpler one than this! To show how you can use it for more general commands and shortcuts, you can very easily make the ultimate stackoverflow keyboard, or one that is able to copy and paste.The command for copy is CTRL + c and the command for paste is CTRL + p. To add this to the keyboard, replace the call to the SendMacroKeypad method in one of the button press sections and replace it with the code in the image above. You will find all the files needed in this project on my GitHub page. So if key is true (is set at all) we use a switch statement to check which button was pressed and perform whatever action we want to do with it. The Art of the Bodge: How I Made The Emoji Keyboard. You should now be all set up and ready to run both the LuaMacros file and the Autohotkey file. Extract the zip and open it with the.ino file with the Arduino IDE. The next button you press will be the command associated with this action, so use your macro keypad to press whatever button you want to control this action. My main use case for this device is to use it with hotkeys in OBS (Open Broadcast Studio, its a software mainly used by streamers, but useful for capturing any video on your PC). The program will then output a list of all connected devices. A simple and funny project with an Arduino UNO and the famous keypad shield. If you know of a simpler one please link it to me, because I haven't found one yet.It uses only 2 components and no special boards need to be installed for Arduino so it really can't get any easier!
