Some niggling things. These might simply be more my own personal preferences, but I thought I'd point them out anyway.
I'm interested in teaching electronics, arduino, microcontroller classes
No "and" before microcontroller.
PCB, schematic, design for manufacturing
Would schematic usually be plural?
Washtenaw county (Ann Arbor and Ypsi and surrounding areas)
I think serial commas would make it a little less clunky.
Youth often benefit from different teaching techniques. If you have youth that might be interested, have them fill the survey out as well.
"Youths" generally is used in plural; for the second sentence, if you want to keep it singular, toss an "a" in front, if you please.
