Hello, my name is ***** ***** I going to try and assist the best I can. Please start by telling me which arduino board your using? I know you are using C#, but there are other alternatives that I think might work for you with the arduino board. If you could also send me a pic of your hardware would be appreciated.
I think it is great. I would love to help getting another alternative since you no longer want to use EZKeys. However, I do need to know the Arduino board model, and possibly the code too. Is your sone available to get that info?
I understand. No worries. Wish I could have been of more help. But without at least some of that info, I am at a loss and would not be able to help you further. I wish you luck, and truly hope that someone out there who has extensive C# ***** skills can help you. Myself I am an Arduino geek, and have done several projects with them. Anyways, Take care and God Bless.
I'd recommend finding out what Stephen Hawking uses and try to obtain the same thing.
