This is my first post on this forum. Bought my Arduino starter kit yesterday. I have a project I've been working on with a raspberry pi which is a linear clock with leds showing time. It is supposed to be used at the pre-school where I am working so the kids can see how much time there is left until for example lunch, snack or song gathering.
The problem I had with raspberry was that it was a computer, well.. That's not a problem. But I don't see why I would need a grand operating system like Rasbian to controll my leds and rapsies are also pretty costy considering I don't need most of the "bells and whistles".
So. I have an Arduino, I have LEDS. But since I am pretty much a total beginner at Arduino I don't really know which extra parts I need to controll all the LEDS I want to use.
What I want to do: Controll at least 20 LEDS individually depending on the time of the day. When pre-school opens at morning = all LEDs are HIGH Then every half hour one LED goes LOW etc.
Question (if it was to much text above): Which parts do I need to acheive this? The code I can learn through reading books and online. But in order to experiment my way forward in the project I want all parts availible in my home.
