Good questions BoRRoZ. It is because of we just started, with a couple of hours during the Meetup with an introduction from Heerd Jan, who is helping the tennis tournament for children in Woerden. They like to see a modification of their score board so they can see the score online. The current score board looks like this:
The idea is to add tilt sensors to each yellow and red flip boards to make this happen. Then we can connect the tilt sensors to an The Things Uno, and from thereon move the data to for example Node Red > Website.
After the introduction of tennis Ludo started to present about TTN and we created small groups to find out about connecting the tilt sensors and measuring it on the Arduino. Another group was investigating how to install Node Red and how it is working. After a couple of hours we decided to move the project to an online environment. So now that is going on. I expect that some of the attendees will put their code on Github soon, so that this will be visible for you and others.
We can use help with Arduino code optimization, suggestions how to make the measures of the tilt sensors visible on a website, if possible without hosting costs for things as Node Red, maybe it can be done by IFTTT as well or so. and help with coding the CSS/HTML to show the scoreboard and the position of the flips.
Hope this make more clear.
