Hello,
we are building a basketball scoreboard for a colleges sports hall from scratch. We already sorted a big part of technicalities, but the big question remains - what type of communication to use for board control.
Basic structure can be seen in the picture:
There is a main controller that controls everything while sending out the signals.
Then, there is the main scoreboard along with two separate attack timers that has to work in sync with everything.
Each part will have their own microcontroller (right now we're building it on Arduinos, but in the end result we'll be using Atmega chips)
Currently we are thinking on sending ALL data via the main controller, including main scoreboards count down timer adjusted to the controllers Real Time Clock unit. Since the distances are quite big (around 50 meters from one side to the other) we're considering a wireless solution. We would be very thankful for your advice on what should we use for the communication and how to maintain a steady synchronized connection between all those parts.
Thank you in advance,
Algimantas D.
