[Imc-makerspace] Servo Questions

[Chris Ritzo]

Hi Brady,
The Makerspace is definitely a place you could talk through some ideas for
this project and maybe start working on a prototype. We have some members
who have worked with arduino and could talk about how to get the project
moving. Stop by during our open hours sometime.

Best,
Chris
