<h3>Speedometer Clock</h3><p>Inspired by analog dials of a retro motorcycle. It shows time in hours and minutes in a pair dials which resembles a tachometer and speedometer. The time is fetched from the Time Server and constantly updates it. The needle movement is controlled by two servo motors.</p><h5>Recommended Print Settings</h5><p>Nozzle &nbsp; : 0.4mm<br>Material &nbsp; : PLA<br>Color &nbsp; &nbsp;: Any<br>Layer Height &nbsp; : 0.2mm<br>Infill &nbsp; : 15% (rectilinear)<br>Supports &nbsp;: None<br>Rafts &nbsp; &nbsp;: None<br>Print Time : &nbsp;~12 Hr.</p><p><strong>Note:</strong><br>Clock_Face.stl :</p><figure class="image image_resized" style="width:71.88%;"><img src="https://media.prusaprinters.org/media/prints/69730/rich_content/4c4db205-cc4e-4f62-9466-e408d7ab0724/6.jpg#%7B%22uuid%22%3A%22284234db-e842-47d8-83c1-1574e7ca914e%22%2C%22w%22%3A1920%2C%22h%22%3A1080%7D"></figure><p><br>Lower Layers must be printed with material that pass light if backlight is needed. Add 3 or more top solid infill for preventing the backlight penetrating through unwanted areas<br>Print in Two Colors. You can print multiple colors in single extrusion printer by filament change method. For that Use M600 Command After 3/4 Layers (for 0.2mm layers) in the GCODE .<br>In Prusaslicer you can add colors easily without messing up with GCODE and view the code graphically for more convenience.<br>Print a minute hand and an hour hand.</p><h5>Hardware Requirements</h5><ul><li>Node MCU &nbsp;x1</li><li>SG90 360 Degree Servo Motor x2 (Normal 180Deg Servos won't work directly unless you modify it)</li><li>DC Socket (DC-022) &nbsp;x1</li><li>M3 Screw(½") &nbsp;x6</li><li>Screws (For Servo, NodeMCU)</li><li>LEDs(Optional - For Backlight)</li></ul><h5>Software Requiremts</h5><ul><li>Arduino IDE</li><li>Libraries<ul><li>Basic ESP8266 Libraries<br>NTPClient by Fabrice Weinberg</li></ul></li></ul><h5>Assembly Instructions</h5><p>Place NodeMCU and Servos as shown in the images.</p><p>&nbsp;</p><figure class="image image_resized" style="width:58.9%;"><img src="https://media.prusaprinters.org/media/prints/69730/rich_content/97ec7899-d5fc-418b-8051-1c060203c73a/description.jpg#%7B%22uuid%22%3A%22c766a697-e53e-4ea3-a5d6-be84ad080dda%22%2C%22w%22%3A4973%2C%22h%22%3A3493%7D"></figure><p><br>Flash NodeMCU with codes attached.
