Recently, I had the chance to use the latest model manufactured by Geeetech, i.e. the 3D Printer Prusa I3A Plus. They launched this new version on the market focusing on the most evident innovation: the external control box that embeds all the electronics; Power unit, front panel LCD and rotating switch, SD Card slot, main board controller and motor controllers, and the switching power unit.
The first article introduces a small board that, using four daisy-chained shift registers, enhances Arduino with a general-purpose extension of up to 32 output ports; it works on most Arduino boards and Arduino-compatible devices. The second article completes the discussion introducing a practical application: controlling four 7-Segments LED displays with only three Arduino Pins, simply using the daisy-chained shift registers.
The PCB only or the fully assembled circuits are available on Etsy.com and Tindie.com, while more technical details can be read on the Arduino Kits section of the Projects in the pages from where sample software, the Arduino libraries and the data sheets are available for free download.
Sold by Balearic Dynamics in a pre-assembled kit, the Alphanumeric LCD for Arduinois based on the use of the Shift-out Register 74HC595 chip. This means that with only three pins of the Arduino board users can benefit of a great tool adding this component to their projects.
For those users interested in the details, curious, Arduino fans, or DIY lovers, they can get the component datasheet, the sample software and the circuit schematics and layout of this project on elctroschematics.com.
Detailed information on this project has been published just today by the Electroschematics.comsite in one of the last articles. Not only but all the interested users should wait few more days to read the second part of the article entirely dedicated to the software aspects of the usage of the display in conjunction with their Arduino projects.
