re: getting into Audrino computer controllers

Last night did the first ten lessons, getting the programming syntax down mainly. I have a good understanding of most of it. I did really like learning how to use the shift register and the other parts I knew what they were but now how they worked.

My useless invention will be a dog scratcher. What I envision is a linear actuator with a high torque medium rpm motor at the end. The motor will turn something like my dog's favorite round brush. the actuator will go back and forth.

The dog will turn the system on via a pressure switch and it will shut off after a set amount of time, and be locked out for a set time.

Shouldn't be too hard.
