Single Key Mechanical Keyboard - QT PY

prusaprinters

<p>I saw the Arduino QT PY while ordering online and thought it would be perfect for a single key keyboard, being only slightly larger than a MX switch.</p> <p>This is made with just a QT PY, two wires, a 1kohm resistor and a Cherry MX Blue switch. It has a really small amount of code to act just like a normal key. I could also make it a macro.</p> <p>I have included the .ino to flash the arduino with. It is currently set to be the button f, easily changed by changing the ASCII number from " char button = 102;" to something else. It could also be easily changed to a macro.</p> <p>Below is the basic wiring and there is also a photo of how the internals are wired above.</p> <p>There is a pinhole on the front of the keyboard case so that the reset/bootloader button can be pressed with a pin.</p> <p>EDIT: I have now included code that was found on the below post by user paa36308. for Morse code support !</p> <p><a href="https://forum.arduino.cc/index.php?topic=600356.msg4095406#msg4095406">https://forum.arduino.cc/index.php?topic=600356.msg4095406#msg4095406</a></p> <h3>Print Settings</h3> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div> <p><strong>Resolution:</strong></p> <p>0.16 with adaptive layer at 0.7 at slanted top of main body</p> <h3>Wiring:</h3> <p class="detail-image"><img src="https://cdn.thingiverse.com/assets/92/bb/f2/ef/70/wiring.png"/></p> </p> Category: Computer
