Make a typewriter with an old keyboard, dot matrix printer and Arduino
Francisco Reinoso has found a fun way to use technology that ordinarily would probably be left on the footpath for the garbage collection. He has used an old PC keyboard with the original DIN-interface, a dot-matrix POS printer with a Centronics interface and connected the two with an Arduino. This results with a project whereby the user can simply type something on the keyboard, press enter - and the text is printed. For the non-believers, check the following video where Francisco runs through the entire project:
This is one of those projects that show how easily you can control something with an Arduino. For the sketch, notes and schematics download Francisco's pdf file. And we're on twitter and Google+, so follow us for news and product updates as well.
Although working with a Centronics interface is easy with Arduino, there are some devices that use a 3.3V line voltage instead of 5V. When you're faced with this situation - don't panic! Make sure you have some of our LEVEL: bidirectional 5V-3.3V level converters in stock. For more information and to order, click here.
