Arduino Verkstad AB, the Swedish branch of Arduino, has developed a prototype that demonstrates a smart transducer network with a self-configurable communication protocol. The protocol is called I2C+, since it is based upon I2C. One of the possible areas of application is the EU funded PELARS project, where Arduino Verkstad is responsible for creating educational tools. Within the PELARS project, a maximum number of transducer modules is expected to be 20 modules, connected at the same time.The aim of this thesis was to create a testing tool and a test suite for the prototype system, which later could be used and also further developed by engineers at Arduino Verkstad, during the development of the final product. Though the testing tool was primarily needed for this particular system, it was considered desirable if it could be reused for similar projects as well.It was relevant to create the testing tool and the test suite in order to analyse the validity of the I2C+ protocol, which might become Arduino's future standard in connectivity between smart transducers. The performance of the I2C+ protocol also affects the implementation of the smart transducer system within the PELARS project.This work has been guided by a specification of requirements and also by a systematic top-down approach of solving several subproblems. A testing tool and a test suite was created, which serves as a proof-of-concept. The testing tool has a modular design, which makes the solution reusable for other purposes. The testing tool and the test suite was validated by using Arduino's prototype as a test object. Although only 10 transducer modules was used during these tests, the results showed that the prototype does not perform well for a growing number of modules. Therefore, improvement of the system and further testing is advised.

Context: Solar panels are exposed to different weather conditions and get damaged. Sand storms and hail storms could cause serious damage. However, they need to be used for human survival in almost every harsh condition possible. Objectives: Our goal is to design and create a working prototype of an automated solar panel shield. The meteorological conditions around the solar panels should be monitored, including wind speed, air quality, rain, and humidity. The shield automatically protects the solar panel based on the sensor data. The solar shield should even protect panels from harm from small animals. Methods: A microcontroller Arduino Uno is used. Various sensors are used to monitor multiple weather conditions, including an ultrasonic sensor, a rain sensor, a smoke sensor, and a custom-built anemometer. Based on daylight status, the stepper motor is activated to roll up the protective cover over the solar panel. Results: The output from all the sensors and actuators is verified. The values of the sensors are updated in the web application, the user can use that. The web application is used to monitor the weather conditions around solar panels. Conclusions: An working model of the shield is made, in addition, a cleaning system is made. A bird deterring system is also included. All the additional sensors for monitoring can be used for performance automation.

What is the purpose of medication? It’s job is to cure a disease.But taking medicine at the perfect time will definitely help anyonecure diseases immediately. There are so many situations when missingmedicine timing might happen unintentionally or even expected. Forexample, there are diabetic people who miss their shot of dose atperfect timing. Another example is the people with memory issuesdue to age or disease.There are many situations where missing medicine might causeproblems. Mainly in crisis situation like in hospital we need a re-minder that helps people take the preferred medicine at specified time.So that will be the problem statement of this thesis.The main objective of the thesis is to notify patient take correctmedicine with the help of easy equipment. When elders have a prob-lem we admit them in hospitals but due to COVID epidemic situa-tions hospitals are understaffed. Because of that the patients in hos-pitals may not be treated well. The personal has a busy schedule withCOVID situations so they can’t care must about each and every singledetails. This might causes major problems while giving minute dosesto patient where a 1mg medication change can lead to severe problemsfor a patients health condition. By providing a proper check up withpatient we can solve those problems more effectively.

Learning to play the piano usually involves learning to read sheet music and many hours of prac- tice, which can be seen as a tough task for beginners. This project presents an innovative ap- proach to piano learning by integrating a Raspberry Pi, Arduino, and LED lights with a Casio CTK-550 keyboard. This system interprets MusicXML files and visually guides users by lighting up the keys they need to press in the correct order, providing a more intuitive and engaging learn- ing experience. Additionally, it has a playback mode that makes the piano play the chosen song while illuminating the keys played. This allows the user to hear the song being played correctly before using the interactive mode to play the entire song themselves. These modifications to the piano aim to simplify the learning process and ease in new piano players by removing the big initial barrier of understanding sheet music. The project practices sustainability by reusing components from old projects and also follows several UN Sustainable Development Goals. After a few iter- ations, there was a product able to fulfill the goals set in advance. Future improvements could include improved lighting precision, additional learning modes, and more user-friendly file transfer possibilities.
