Tell us about yourself!
Great work. explains this clearly. I never used circuit schematics i just had my own symbols but when it came to building something from an already designed schematic i got stumped
Yes please do. I can somewhat recreate the circuit by just looking at it but i wont jump to conclusions.
I think its a small transformer. Bigger ones can run around more voltage.
You can find many of these things at the parallax website
So how long is the range? a foot? or do i need to touch the object to damage it?
2-4m is exactly what i need. this is gonna be fun.
