This image illustrates the first working prototype of the BODIPA (Bay Observation Drone Interchangable Payload Attachment). The setup includes an Arduino connected to my laptop, which is running a program designed to control a push-button stepper motor. The Arduino board is equipped with a push button that is wired to a motor controller. When the button is pressed, a signal is transmitted to the controller, prompting the stepper motor to rotate in one direction for a predetermined duration. 

Upon completion of this time interval, the motor initiates a waiting period before reversing its direction and rotating for the same duration in the opposite direction. This functionality enables the stepper motor to unreel a line, allowing the sensor box to be lowered into the water. Once submerged, the sensor box will perform its designated tasks while the motor remains in a standby mode. Subsequently, the motor will retract the sensor box, bringing it back up to the drone.
