abstract = {The Internet of Underwater Things (IoUT) is an emerging approach composed of a network of underwater devices, such as sensors, vehicles, and communication nodes, that collaboratively collect, transmit, and analyze data for applications such as ocean monitoring, underwater exploration, and defense. The vision of IoUT includes significant challenges for communication due to signal attenuation, multipath interference, and limited bandwidth. This paper presents the design, implementation, and evaluation of a basic underwater acoustic communication system. One of the purposes of this paper was to explore how components coming from the Internet of Things (IoT) ecosystem can be integrated into the IoUT paradigm. Therefore, we compare a microcontroller with a signal generator for the signal generation process to evaluate performance trade-offs. Performance was assessed across configurations in a pool environment. Key findings include reliable communication at 300 bps up to 6 meters (BER <10\% with Hamming encoding) and reliable performance up to 1000 bps at 1 meter (BER ≈ 1\%) using a microcontroller instead of a signal generator. This paper demonstrates the first steps to build a testbed to evaluate IoUT solutions that will offer practical insights into the challenges and performance factors of simple underwater acoustic communication.},
