    Question 16x 7 Segment on Arduino?

    I want to control the seven-segment displays a 747 MCP (16 pieces) on Arduino. What exactly do I need for hardware and where can I find a working circuit? Search the web for a long time but there are very different solutions. Another similarly priced variant would also ok.
    However, the control must possible via VB.Net.

    Re: 16x 7 Segment on Arduino?

    Is your MCP going to a scale replica of the real one, or just a functional copy? If you are making a replica, you will need to use displays that are the same size, with custom PCB or hand-wired. If you are making a funtional copy, but can live with the display digits being bigger, then the TM1638/TM1640 boards can used. Connect them to Arduino using SPI (3 wires) and run Link2FS for the interface to FSX. the code is super simple, and works great. They are available with up to 16 digits per board, and are cheap on ebay.com or dx.com. Look in the Link2FS sub-forum here and you can see lots of code examples too.
