This project was about getting a nerf gun to short at people as soon as it sees them using aurduino and a servo motor. I wanted to put in my door way so when people came in the house they would get shot! It took me a lot of materials though. I used wood, wire, a nerd gun, rope, aurduino, servo, and glue. To properly influence these materials i used many tools. I used saws, drills, scissors, computers, glue guns, and a soldering iron. The most challenging part of my project was when i had to 3d print a new servo arm and it didn't fit. The most fun part was shooting Gabe in my presentation. I used instructables.com and the code links from the instruct able page. I had lots of absolutely perfect pictures but i lost them when my I-pad broke.
