The two components of the fishing rod were the casting mechanism and the box for the electronics housing. The casting mechanism is made up of 1/4" acrylic links connected with 6 mm bearings at the joints. Before the final laser cuts of the acrylic links were made, the prototype was cut out of 1/4" wood. The electronics housing is a jigsaw box of 1/4" wood with 3 of the 4 walls glued to each other to minimize the collapsibility, yet retain the ability to open the box and view the circuit. At the bottom of the electronics housing is a 3D printed attachment ah out of PLA with an opening that allows for a weight to be inserted at the front. As a finishing touch, the wood of the electronics housing was painted black to match the color aesthetic of the 3D printed parts.

- 1 Arduino Uno Board
- 1 9V Battery
- 1 270 degree Servo Motor
- 1 Breadboard with at least 2 power buses and 20 terminal rows
- 3 Push Buttons
- 3 220 Ohm Resistors (Each wired in series with one of the buttons)
- Miscellaneous wires to connect components to the breadboard
Software Development
Below is our code used by the Arduino to control the position of the servo. We ended up only using two of the three buttons since we ran out of time to fully develop the reel mechanism. The code below controls the position of the rod with two buttons.
