Re: Building an outdoor scoreboard..

Standing on the shoulders of giants - I used Joe's spreadsheet to create the font. Posted it here if you are interested. Of course, I would re-factor the code if I had to do it again and might even use a Linkit Smart Duo MT7688 as the front end, cheaper than a Yun and can be easily adapted for an ex...

Re: Yet another scoreboard - Software

Software A simple message format between Arduinos was designed and uses the REST features of the Yun to send the messages to the Arduino side from the Linux (OpenWRT) side. The messages are then sent over the serial port to the first Arduino which then sends all messages on the next Arduino. After ...

Re: Yet another scoreboard

Battery power Part of the design brief was that the scoreboard should be portable so we needed to get a suitable battery powered supply. The scoreboard would also be used outdoors and perhaps in bad weather so we looked around to see what might already exist in order to avoid “re-inventing another ...

Re: Need a little help DMD and Serial Input

Like many people I have built a scoreboard. It is controlled by an Arduino Yun and because the first version of the library did not support Yun/Leonardo, it sends a serial message to a second Arduino Uno to control the display. I tested it all running the serial comms at 9600 and it worked with one ...
