I'm trying to decide how to best activate a couple things on my robot build (full sized K-9 in my avatar).
I need to turn on a laser pointer. I'm thinking a pico switch would work.
Is there a more direct solution with the EZ B (I'll be upgrading to v4 soon)?
Also, I need to move a car antenna up and down. This particular antenna requires reversing the polarity to get it to move backwards. A switch that's mechanically activated by a servo arm for one direction and another switch for the other direction would definitely work and I'd just need to control the duration of the switch's activation to control how far the antenna extends.
Would a relay be any better? Reversing the polarity appears to be more challenging for my feeble brain-- the simpler the better :)!
This one seems to be able to run things forward and backward, but I'm not sure how it'd work with the EZ B.
thanks in advance
