at the moment I’m preparing a presentation stand about Open Educational Resources for an education fair this weekend. The goal is to inform people about the benefits of publishing their teaching materials free and under open licenses. I thought about ways to make the stand a little bit more interactive and had the idea to add something like a Creative Commons calculator for teachers to play around with, whenever the stand is unsupervised for a few minutes.
I would like to connect a few buttons (two pins) and an LCD (2X16) to an Arduino Uno R3. Five buttons for the CC-Elements “Zero”, “BY”, “SA”, “NC” and “ND” and one button to reset the text on the LCD. As default the abbreviation CC should be displayed in the first row of the LCD. Whenever you hit one of the buttons, an element like BY or NC gets added to the License. If it is a valid License, it says “Valid License” in the second row of the LCD, when you typed in elements that don’t mix, like CC Zero-SA-ND, it says “This is not a valid license.” The reset button obviously resets everything that was typed in and the default CC appears in the first line.
This is my first project with an Arduino and to be honest, I’m generally not too savvy when it comes to working with electronics and programming. I always wanted to start learning about it though, so I thought, this might be a good project to get started. I bought all components and tried getting it to work, but I guess I underestimated the complexity of the project for a complete beginner.
I’ll attach a screenshot of the circuit diagram. At the moment I’m pretty undecided, if it will work or just explode in a big ball of fire.
When it comes to code, I don’t even know where to start, yet…
Would you please help me with this project? I would extremely appreciate it. Until then I’ll keep my fire extinguisher ready…
Thank you very much!
