Thermometer for LACK enclosure, Arduino

prusaprinters

<p>This is an Arduino based OLED thermometer for IKEA LACK enclosures.</p> <p><br/></p> <p>This project uses an Arduino Uno as it has an on-board voltage regulator that would accept the same 12 volt supply that I am using for the LED lighting. Other models such as the Nano and Micro will also work and can be powered from an USB supply.</p> <p>The display is a slimline 0.91 inch 128 x 32 pixel OLED display. This is fixed into the display bezel using a small amount of epoxy resin from the rear.<br/> The Bottom fill pattern is "Octagram Spiral" to get the effect on the display bezel.</p> <p>The cutout for the display is made from two 16mm holes at 42mm centres. The Arduino holder also uses the 16mm drill.</p> <p>Temperature sensing is by a Dallas DS18B20 sensor, this can be positions where you require within the enclosure.</p> <p>All the cabling is routed internally as the LACK table has a hollow interior, you just need to push the cardboard hex out of the way.</p> <p>The Power socket allows the connection from the power supply to be recessed unto the LACK so that it can still sit close to the wall at the rear.</p> <p>Credit to <a href="https://www.thingiverse.com/martinfun1987/designs">Martin Schermann </a> for the <a href="https://www.thingiverse.com/thing:222680">Arduino base.</a></p> <h3>Print instructions</h3><p>Arduino code is available from my GitHub:</p> <p><a href="https://github.com/chillygithub/LACK_thermometer">https://github.com/chillygithub/LACK_thermometer</a></p> <p>Choice of Font is now available.</p>
