Then, use your hands to carefully wiggle the extra two columns off. Finally, remove the extra row. Remember to save these extras somewhere safe, you can use them for another project later! ![gaming_fourByfour-2579.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/110/medium640/gaming_fourByfour-2579.jpg?1630098484) ![gaming_fourByfour-2580.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/111/medium640/gaming_fourByfour-2580.jpg?1630098559) Info: [Numpad 4000 Guide](https://learn.adafruit.com/numpad-4000-mechanical-keyswitch-data-entry-device/assemble-the-numpad) ![](https://cdn-learn.adafruit.com/assets/assets/000/104/112/medium800/gaming_fourByfour-2581.jpg?1630098590) ## Wire the NeoKey PCBs and QT Py Follow the guide and photos below to wire up the four colums, four rows, power, ground, and NeoPixel data line. ![](https://cdn-learn.adafruit.com/assets/assets/000/104/113/medium800/gaming_keypad_4x4_fritz.jpg?1630098836) Start by wiring the power, ground and columns. I used thin, silicone covered wire, which is nice and flexible. It is thin enough to thread through the PCB holes without first stripping the insulation, which makes it easier to "tighten" things to even lengths all at once. After that you will cut, strip, and solder. ![gaming_fourByfour-2582.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/114/medium640/gaming_fourByfour-2582.jpg?1630098978) ![gaming_fourByfour-2583.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/115/medium640/gaming_fourByfour-2583.jpg?1630098986) ![gaming_fourByfour-2584.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/116/medium640/gaming_fourByfour-2584.jpg?1630098995) ![gaming_fourByfour-2587.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/117/medium640/gaming_fourByfour-2587.jpg?1630099022) Thread the wires into the QT Py, then add the NeoPixel data wire and the row wires. ![gaming_fourByfour-2589.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/118/medium640/gaming_fourByfour-2589.jpg?1630099165) ![gaming_fourByfour-2590.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/119/medium640/gaming_fourByfour-2590.jpg?1630099198) ![gaming_fourByfour-2591.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/120/medium640/gaming_fourByfour-2591.jpg?1630099206) ![gaming_fourByfour-2592.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/121/medium640/gaming_fourByfour-2592.jpg?1630099231) ![](https://cdn-learn.adafruit.com/assets/assets/000/104/122/medium800/gaming_fourByfour-2593.jpg?1630099252) ## Solder to the PCB Trim, strip and solder the wires on the PCB now. Then, you'll pull the wires to length on the QT Py side of things. ![gaming_fourByfour-2594.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/124/medium640/gaming_fourByfour-2594.jpg?1630099954) ![gaming_fourByfour-2595.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/125/medium640/gaming_fourByfour-2595.jpg?1630100507) ![gaming_fourByfour-2596.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/126/medium640/gaming_fourByfour-2596.jpg?1630100524) ![](https://cdn-learn.adafruit.com/assets/assets/000/104/123/medium800/gaming_fourByfour-2601.jpg?1630099768) ## Board Positioning Now you can place the QT Py toward the center of the PCB and pull the wires to even lengths with a little bit of slack. ![gaming_fourByfour-2602.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/127/medium640/gaming_fourByfour-2602.jpg?1630100834) ![gaming_fourByfour-2606.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/129/medium640/gaming_fourByfour-2606.jpg?1630100981) ## Solder to QT Py With the wires tightened up, you can now trim, strip, and solder them to the QT Py as shown here. ![gaming_fourByfour-2608.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/130/medium640/gaming_fourByfour-2608.jpg?1630101127) ![gaming_fourByfour-2609.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/131/medium640/gaming_fourByfour-2609.jpg?1630101134) ![gaming_fourByfour-2610.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/132/medium640/gaming_fourByfour-2610.jpg?1630101142) ![gaming_fourByfour-2611.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/133/medium640/gaming_fourByfour-2611.jpg?1630101150) ![](https://cdn-learn.adafruit.com/assets/assets/000/104/134/medium800/gaming_fourByfour-2615.jpg?1630101193) ## Add Switches to Plate and PCB Click your switches into the plate and then into the PCB. Be mindful of the orientation and check that the legs line up with the sockets before pushing switches into place. ![gaming_fourByfour-2684.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/135/medium640/gaming_fourByfour-2684.jpg?1630101246) ![gaming_fourByfour-2683.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/136/medium640/gaming_fourByfour-2683.jpg?1630101325) ## Case Assembly To assemble the case, first drop the switch plate in and screw it in. ![](https://cdn-learn.adafruit.com/assets/assets/000/104/151/medium800/gaming_fourByfour-2685.jpg?1630101400) ![](https://cdn-learn.adafruit.com/assets/assets/000/104/158/medium800/gaming_fourByfour-2687.jpg?1630101617) ## USB Port Extension Use the short DIY ribbon cable and straight USB port and jack to create an easy to use connector. This fits very nicely compared to the QT Py, which will not lay flush at the port end of the case due to the keyswitch sockets. ![gaming_fourByfour-2688.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/159/medium640/gaming_fourByfour-2688.jpg?1630101795) ![gaming_fourByfour-2689.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/160/medium640/gaming_fourByfour-2689.jpg?1630101804) ![gaming_fourByfour-2690.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/161/medium640/gaming_fourByfour-2690.jpg?1630101812) ![gaming_fourByfour-2691.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/162/medium640/gaming_fourByfour-2691.jpg?1630101825) ### Adhere Use an adhesive square or double stick foam tape to adhere the bottom of the USB port extender to the metal mid-plate as shown. This will make the port stable enough for plugging and unplugging the USB cable. Make sure not wires or ribbon cable are pinched by the plate as you close it. ![gaming_fourByfour-2692.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/163/medium640/gaming_fourByfour-2692.jpg?1630102572) ![gaming_fourByfour-2693.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/164/medium640/gaming_fourByfour-2693.jpg?1630102587) ![gaming_fourByfour-2694.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/165/medium640/gaming_fourByfour-2694.jpg?1630102597) ![gaming_fourByfour-2695.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/166/medium640/gaming_fourByfour-2695.jpg?1630102605) ![](https://cdn-learn.adafruit.com/assets/assets/000/104/190/medium800/gaming_fourByfour-2699.jpg?1630102772) ## Back Plate Screw the back plate into place. Don't crank down too hard on the screws or you may risk cracking the plastic back plate. ![gaming_fourByfour-2697.jpg](https://cdn-learn.adafruit.com/assets/assets/000/104/167/medium640/gaming_fourByfour-2697.jpg?1630102674) ## Keycap Time Now you can add your keycaps and move on to coding the Deluxe 4x4 Neo Keypad! ![](https://cdn-learn.adafruit.com/assets/assets/000/104/220/medium800/gaming_fourByfour-2698.jpg?1630102895) ![](https://cdn-learn.adafruit.com/assets/assets/000/104/228/medium800/gaming_fourByfour-2701.jpg?1630112520) # Deluxe 4x4 NeoPixel Keypad ## Neo Keypad 4x4 MIDI Controller https://youtu.be/VH65d25tapo?t=1255 In order to make it simple to get up and running with your Keypad with no programming required, we've created a drag-and-drop firmware you can use. You can skip to the section on Custom Code in Arduino if you want to customize it. ## Download First, download the firmware file linked in the button below and save it to your computer hard drive somewhere you'll be able to find it, such as your **Downloads** folder. [Keypad 4x4 Clocked uf2](https://cdn-learn.adafruit.com/assets/assets/000/104/229/original/key4x4.UF2?1630114331) ## Install the Firmware Plug your QT Py into your computer with a good quality, data capable **USB** cable. Life is too short to go through the pain of accidentally using a **power-only** USB cable, so please round up any you own, cut them in half, travel to a distant land, bury them, and dance on their grave. Your QT Py will start up with whatever code was running on it. Let's change that! ## Bootloader Mode Now, we'll put the QT Py into bootloader mode. In this mode it will appear as a USB drive on your computer and will be ready to receive a new .uf2 firmware file. Double-click the reset button on the top side of the board (you will need to open the case to do this if you previously closed it). The **QTPY\_BOOT** drive will show up on your computer. Simply drag-and-drop the **key4x4.uf2** file onto it. It will copy the file and then automatically restart, running the code! ## Play It Now you can run the synth software of your choice (or hardware synth with USB MIDI Host capabilities) and pick the **QT Py M0** as your active MIDI input. The code will run at a clock rate of 120 BPM, sending MIDI clock, and when you press the keys you can play an A major chord (plus bonus G#) in two octaves. ## Custom Code in Arduino If you'd like to customize things further, you can edit the code in Arduino. Open your Arduino IDE. If you are new to Arduino, check out this guide: [Adafruit Arduino IDE Setup](https://learn.adafruit.com/adafruit-arduino-ide-setup?view=all). You'll also need to make sure you've updated your Board Definitions to the latest version the SAMD boards by heading to **Tools -\> Board Manager** in the **Arduino IDE,** filter for "Adafruit SAMD" and choose the install or update. You'll also need to install the Tiny USB library, Keypad library, MIDI library, and NeoPixel library. https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Keypad_4x4_Clocked/Keypad_4x4_Clocked.ino ## Customization ### Latching The main thing you may want to customize is the behavior of the switches -- do they latch or are the momentary? Adjust this line from false to true and you will have each key latched as a NoteOn message when you press it. Press it a second time to unlatch it and send NoteOff. ```cpp bool latch_mode = false; // set latch/toggle mode ``` ### BPM clock Beyond that you can change the BPM (note PPQN may vary between synths/softsynths so you may need to subdivide to get the desired clock rate). ``` intBPM =120;// set BPM ``` ### MIDI Channel You can also pick a different MIDI out channel: ``` intMIDI_OUT_CH =1; ``` ### Scales The array called `pads[]` determines which notes are sent. You can adjust this to suit your needs. By default, the Neo Keypad sends two different octaves of A major scales with a bonus G#. ``` intpads[] = {// two A scales with added G#76,77,79,80,69,71,72,74,64,65,67,68,57,59,60,62}; ``` Uncomment this array for a chromatic set of notes that correspond to the pad launching mode of the 1010Music blackbox: ``` /\*int pads[] = { // corresponds to 1010music blackbox pads for sample launching 48, 49, 50, 51, 44, 45, 46, 47, 40, 41, 42, 43, 36, 37, 38, 39 };\*/ ``` ## Featured Products ### 4x4 Key Deluxe Aluminum Keypad Shell Enclosure [4x4 Key Deluxe Aluminum Keypad Shell Enclosure](https://www.adafruit.com/product/5071) For all the DIY keebfans in the house here is a very fancy and sturdy **4x4**   **Keypad Shell in Dark Gray** with silver accents, the perfect base to begin your custom...
