Tell us about your project:

It's a catapult alarm clock! what better way to wake up than to have a catapult launch a remote control necessary to turn off the infernal buzzer blaring in your ears across the room. This project uses an Arduino uno, rtc, ir remote, dc motor, buzzer and of course a catapult made from household materials to make your mornings a little more interesting. This is my first time documenting a larger project, so hopefully, it makes sense and you learn about things besides my hatred of buzzers and desire to somehow make a servo work on the catapult.
