Al een tijd zit ik met de gedachte te spelen om een ‘ouderwets’ LED display aan te sturen met de Arduino. Dit zal dan via multiplexing moeten gaan, een voor een 1 cijfer tonen, dat heel snel achter elkaar zodat het lijkt alsof ze allemaal aanstaan. Ik maak gebruik van een 7447 (7 segment driver IC) en een 74138 (3 line to 8 line decoder) om de 6 display’s aan te sturen met 3 draden. En een hulp IC 7404 (hex inverter), 6 tal NPN transistors en wat weerstanden.<\/p>

Op zich een simpel project, niet perfect werkend, maar het gaat mij om de techniek erachter, kan ik maken wat ik in mijn hoofd heb?<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
