An Arduino-powered fishing pole with automatic casting and reeling

YouTuber MrTeslonian was asked if he could create an automatic fishing pole for someone with a serious disability. While this would seem like a daunting task, he was able to build one using a spring-loaded mechanism, a number of motors, and an Arduino board.

His portable device takes commands over WiFi, allowing control from a smartphone or computer. When it receives the signal, the pole is automatically pulled back and tension is added to a large spring via a winch. This tension is then released with a servo-actuated system, and a small gearmotor reels the bait back in… hopefully with a fish attached!
