Iedereen kreeg een <strong>gepersonaliseerde badge </strong>met in het geheugen ervan ieders unieke "id". Dankzij het <strong>scannen van deze RFID-kaarten</strong> wisten we perfect wie er wanneer (of niet) kwam eten, en (veel belangrijker) hoeveel maaltijden er konden uitgespaard worden ('big data').</p> <p><img alt="" src="//www.ottenbourg.com/blog/uploaded_images/BadgeScanning.jpg" /></p> <p>Het (her)schrijven van deze chip-kaarten zal nu <strong>gemakkelijker en vlotter</strong> kunnen op Suikerrock dankzij deze <strong>nieuwe reader/writer</strong>...</p> <p>Wat ging eraan vooraf?</p> <p><strong>STAP 1 : COMPONENTEN</strong></p> <p>De basis voor dit project is een <a href="https://store.arduino.cc/arduino-uno-rev3" target="_blank">Arduino Uno</a> micro-controller aangevuld met :</p> <ul><li>een <a href="http://wiki.sunfounder.cc/index.php?title=PN532_NFC_RFID_Module">PN532 NFC/RFID Wireless module</a> met SPI-interface. Twee PINs voor stroom en 4 PINs voor data.</li> <li>een LCD (Liquid Crystal Display) schermpje met 2 lijnen en max. 16 karakters per lijn. Deze (LCD1602) wordt <a href="https://www.sunfounder.com/learn/Sensor-Kit-v2-0-for-Arduino/lesson-1-display-by-i2c-lcd1602-sensor-kit-v2-0-for-arduino.html" target="_blank">aangestuurd via de I2C-bus </a>waardoor er maar 4 PINs nodig zijn!</li> <li>een <a href="https://www.adafruit.com/product/419" target="_blank">3x4 Membrane Matrix Keypad</a> van Adafruit. De 4 rijen en 3 kolommen gebruiken in totaal maar 7 PINs voor 12 verschillende toetsen.</li> </ul><p><img alt="Arduino en gebruikte componenten en modules" src="//www.ottenbourg.com/blog/uploaded_images/SR_2017_RFIDwriter_2.jpg" /><strong>STAP 2 : PROGRAMMEREN</strong></p> <p>De <a href="https://www.arduino.cc/en/tutorial/sketch" target="_blank">Arduino sketch</a> (code) is vrij klein (10Kb) en na een initiele setup, wacht het programma (in een lus) tot er een RFID-kaart wordt aangeboden. Deze wordt dan gelezen (indien compatibel) en de 'id' wordt weergegeven op het LCD-scherm.<br /> Vervolgens vraagt het programma of de kaart moet (over)schreven worden. Indien "Yes" (#-key), kan men een 8-cijferige code ingeven en bewaren (opnieuw #-key) op de chipkaart. Indien "No" (*-key) wordt er terug gelezen.<br /> Na het (her)schrijven van een 'id' wordt de kaart opnieuw gelezen ter bevestiging van de nieuwe code.</p> <p><strong>STAP 3 : 3D PRINTING</strong></p> <p>Met behulp van de (gratis en online) <strong>3D CAD software</strong> van Autodesk (<a href="https://www.tinkercad.com" target="_blank">Tinkercad</a>) maakte ik vervolgens een 'doos' met alle nodige uitsparingen. Deze werd vervolgens (in Montréal, want ik was toevallig daar) geprint via <a href="https://www.3dhubs.com" target="_blank">3Dhubs.com</a> in 2 delen (PLA, 100μm).</p> <p><img alt="3D print" src="//www.ottenbourg.com/blog/uploaded_images/SR_2017_RFIDwriter_1.jpg" /></p> <p>STL-bestand te bekijken en te downloaden via <a href="https://www.thingiverse.com/thing:2406380" target="_blank">Thingiverse</a>.</p> <p><strong>STAP 4 : ASSEMBLAGE</strong></p> <p>Na het samenstellen en <strong>vastlijmen</strong> van alle componenten, nog snel een <strong>allerlaatste test </strong>voor dat de doos definitief wordt dichtgelijmd.</p> <p><img alt="" src="//www.ottenbourg.com/blog/uploaded_images/SR_2017_RFIDwriter_3.jpg" /></p> <p>Total kostprijs 40EUR (aan materiaal) plus 40EUR voor de print.

programmeren</strong>, van hard- en sofware.... Eerst <a href="https://nl.wikipedia.org/wiki/Raspberry_Pi" target="_blank">Raspberry Pi</a>, maar sinds enkele weken vooral <a href="https://nl.wikipedia.org/wiki/Arduino_(computerplatform)" target="_blank">Arduino</a>.<br /> Beiden zijn zogenaamde "<strong>micro controllers</strong>", soort van <em>mini-computers</em> zeg maar, niet veel groter dan bankkaart, die je kan programmeren en waarmee je hardware (lampjes, relays,...) kan aansturen.</p> <ul><li><a href="https://www.raspberrypi.org" target="_blank">Raspberry Pi</a> is zo goed als een volwaardige computer met een besturingssysteem (Linux) en opslaggeheugen</li> <li>Een <a href="https://www.arduino.cc" target="_blank">Arduino</a> heeft geen besturingssysteem of opslaggeheugen en is dus minder complex</li> </ul><p>In de industrie gebruikt men voor dit soort toepassingen de benaming <strong>PLC</strong> (<a href="https://nl.wikipedia.org/wiki/Programmable_logic_controller" target="_blank">Programmable Logic Controller</a>, of Programmeerbare Logische Eenheid).</p> <p>Op aangeven van een <a href="http://frederickvandenbosch.be/?p=359" target="_blank">blog-post van Frederick Vandenbosch</a> wilde zelf wel zo eens een "<strong>kerst-ster</strong>" maken. En dit is het resultaat (voor en achterkant)!</p> <p><img alt="Arduino project NeoPixels" src="//www.ottenbourg.com/blog/uploaded_images/Arduino-kerstster.png" /></p> <p>Een basis <a href="http://www.arduino.org/products/boards/arduino-uno" target="_blank">Arduino Uno</a> had ik al liggen, de 5 <strong>RGB LED-strips</strong> (<a href="https://www.adafruit.com/product/1426" target="_blank">NeoPixel Sticks</a>) werden besteld bij <a href="https://www.adafruit.com" target="_blank">Adafruit</a>, de <a href="https://www.thingiverse.com/thing:624811" target="_blank">3D-versie van ster</a> vond ik op <a href="https://www.thingiverse.com" target="_blank">Thingiverse</a> en voor de <strong>3D-print</strong> gebruikte ik <a href="https://www.3dhubs.com/service/fish" target="_blank">Joe's Hub</a> (hier in Dubai) via de wereldwijde online printing service <a href="http://3dhubs.refr.cc/JWNQV7P" target="_blank">3D HUBS</a>. Eens alles verzameld kon het samenstellen en <strong>solderen</strong> beginnen. Wat lijm aan de verbindingen (hete lijmpistool) voor de versteviging en het programmeren van de LED-effecten ging als een fluitje van een cent.</p> <p>Het leuke aan deze NeoPixels LEDs is dat je alles in serie achter elkaar kan verbinden (solderen) en <strong>maar 3 draden nodig</strong> hebt om elke LEDje individueel te bedienen (5V, GND en DATA)!<br /> De <a href="https://learn.adafruit.com/adafruit-neopixel-uberguide/arduino-library" target="_blank">Adafruit NeoPixel library</a> is heel uitgebreid en aan de hand van de enkele voorbeelden ben je snel vertrokken.</p> <iframe height="360" src="https://www.youtube.com/embed/Y8eWO-Y0Ssg" width="640"></iframe><p> Al bij al een <strong>leuk knutselprojectje</strong> met een praktische toepassing. Volgende stap is de Arduino Uno vervangen door het <strong>veel kleinere broertje</strong> de <a href="https://store.arduino.cc/arduino-nano" target="_blank">Arduino Nano</a>, en dan zijn we klaar voor volgende Kerst!</p> <p>Meer Arduino projecten (o.a. voor Suikerrock) zitten er aan te komen... stay tuned.</p> </div> <!-- END OUTPUT from 'themes/contrib/bootstrap/templates/field/field.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--default--node--field-labels--story.html.twig * field--default--node--story.html.twig * field--default--node--field-labels.html.twig * field--default--field-labels--story.html.twig * field--default--story.html.twig * field--default--field-labels.html.twig * field--default.html.twig * field--theme-ds-field-default.html.twig * field--node--field-labels--story.html.twig * field--node--field-labels.html.twig * field--node--story.html.twig * field--field-labels.html.twig * field--entity-reference.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/contrib/bootstrap/templates/field/field.html.twig' --> <div class="field field--name-field-labels field--type-entity-reference field--label-hidden field--items"> <div class="field--item"><a href="/blog/labels/jan" hreflang="nl">Jan</a></div> <div class="field--item"><a href="/blog/labels/arduino.html" hreflang="nl">arduino</a></div> <div class="field--item"><a href="/blog/labels/diy.html" hreflang="nl">DIY</a></div> </div> <!-- END OUTPUT from 'themes/contrib/bootstrap/templates/field/field.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--default--node--comment-node-story--story.html.twig * field--default--node--story.html.twig * field--default--node--comment-node-story.html.twig * field--default--comment-node-story--story.html.twig * field--default--story.html.twig * field--default--comment-node-story.html.twig * field--default.html.twig * field--theme-ds-field-default.html.twig * field--node--comment-node-story--story.html.twig * field--node--comment-node-story.html.twig * field--node--story.html.twig * field--comment-node-story.html.twig x field--comment.html.twig * field.html.twig --> <!-- BEGIN OUTPUT from 'core/modules/comment/templates/field--comment.html.twig' --> <section> <h2>Reactie toevoegen</h2> <drupal-render-placeholder callback="comment.lazy_builders:renderForm" arguments="0=node&amp;1=1447&amp;2=comment_node_story&amp;3=comment_node_story" token="7sD7mWNLvHgv_S-82C_A3o5wZ9Q3R0ZIwfLTutOCddU"></drupal-render-placeholder> </section> <!-- END OUTPUT from 'core/modules/comment/templates/field--comment.html.twig' --> </div> </div> <!-- END OUTPUT from 'core/modules/layout_discovery/layouts/onecol/layout--onecol.html.twig' --> <!-- END OUTPUT from 'modules/contrib/ds/templates/ds-entity-view.html.twig' --> Sun, 16 Apr 2017 17:23:08 +0000 Jan Ottenbourg 1447 at https://www.ottenbourg.com/blog
