Hello ! This is Leo the Techmaker chain, and today, as you can see, the decor, there is something more. Well as JOJOL with his alarm clock, or FABIENOLICARD with his counter a little more old school subscribers I also decided to have a small counter next to me. But since the chain we are a little more DIY as you know, so do we even directly! And suddenly, voila, it’s right there and now it turns on Youtube, Twitter and Facebook. It would have been possible to add Instagram, but since my use Instagram is extremely low at the moment, I told myself that it was not very interesting. But suddenly I’ll explain how it works and how to reproduce. What are we going to need? Well first of all 5 LED boards. Here we have 5 plates 8×8 which makes us a distance of 40×8 pixels. With this it will be possible to add the logo and 6 digits. Perhaps one day we will come to 7 digits, but if it happens one day we improved the whole system, not worry. Besides these LED panels is going to need something to control, here it will be an Arduino Mega. And finally, some son to connect everything. Once you have all that, you just have to weld the plates together, and then everything connected to the Arduino. Once made and supplied to the computer, well … it is powered and running. The tutorial is just the most at the programming level construction, given that the construction part is over, there’s not much more to do. Sure we could add a frame and a glass front to better disseminate either a glass or a sheet of paper. The problem is that the camera, as you see, it does not do very well I think. It makes better naked than that. But later, perhaps, add a glass and put it in a frame. But in any case, level building was finished. Now, as you see, he currently runs a program. On this program we will have really need three things to the base. Simply access the Twitter API, Facebook and Google. To retrieve the number of youtube subscribers, number of Likes on Facebook and its number of Followers on Twitter. And why must recover these API keys? Well because these sites do not let call the subscriber numbers like this anonymously. It is absolutely necessary to have an identifier so to prevent spam. There are some means for Twitter, but for the other two I have not found very convincing so we’ll have to go through an API. From there it will just be careful that our identification keys are long enough, because for instance Facebook leaves only keys 1 hour at the base if we do not change the setting. And behind, that’s all, simply just call them with the program. Currently the program called every second, ie that every second someone subscribes or unsubscribes the meter will change. Well here, there’s not much more to say, because in the end it’s not a really long DIY in the sense that there is still much less to do with such a console. After unfortunately this tutorial, it’s not me who took care of the programming, but a friend. Since we have not found much on the net to do it directly, it took the code. And then suddenly there is a mixture of C Sharp and C ++ Thereby controlling the data sent and the Arduino itself. The thing is that suddenly, the code is a little messed up. What I want to know is that if we share: Are you be interested that it be shared on a git, so that everyone can improve it openly? Do not Hesitate to say in comment I hope this mini DIY Did you, as usual, all links in the description, as well as links to my social networks. Besides now I can see if you follow me or not. And besides, it’s time to follow me because I made you win that small enclosure 150 € on Twitter and Facebook.
