Schematics for teaching purposes

[SrikanthS-IIT]

Hi there! I am a teacher in an engineering institution, and would like to teach students microcontroller based applications. In addition, I advise a couple of students who are in the Music Club here, so they also would like to build something like this. Would you be able to share some schematics of this device, so that we can try and build it over here? It doesn't have to be perfect - just an idea of the pin connections will more than suffice. The students will be able to figure out the rest.

Thanks!

Hello. I wish I could help out, but unfortunately I never made a schematic for this project and it has been scrapped for parts many years ago. You might be able to figure out some of the pins just by looking through the code. It looks like I put "pin" in a lot of variable names. Sorry I can't be of more help!
