This was one of my first “real” Arduino projects aside from the tutorials in the books and a few little experiments. This was the first time that several things happened. First of all I got two servos and learned how to use them. Being able to see things move was magical. Sure flashing LED’s, serial output and adjusting tones with a potentiometer was fun too, but it was the motors that got me thinking, “hey I can make a robot now, awesome.”
This whole thing started the day before St. Patrick’s day 2014; my wife was busy drumming up leprechaun related stuff on Pinterest and asked me if I could make a leprechaun trap. “Of course” I said – but what and how to build it? I asked my 8 year old son to help me sketch out a rough idea, it involved levers, pulleys, and cages. I knew that I needed more than just the Arduino but also some type of materials that I could easily assemble to the exact size and specification that was on my very much to scale diagram. The only logical solution was to dump all of my kids legos out on the kitchen table/floor and start building.
