| Summary: | This report covers the development of a product with an associated cloud based communityinterface for people who’s attending music events in the EDM (electronic dance music) genre. The product is the result of a further development of a previous prototype. With components as accelerometer, microcontroller, bluetooth module and 7-segmentdisplays have hardware for detecting dance steps as accelerating movement in vertical direction been developed. When a dance step is detected, a counter is incremented and shown on the displays. The purpose of the bluetooth module is to allow the user to connect the hardware to the user’s mobile phone. When connected, the user can take advantage of a mobile phone application which acts as a community interface. The community interface provides functions as displaying user profile, other users profiles, signing up to events, displaying toplists and connecting to bluetooth. This gives the user the opportunity to compete with other users in dancing the most. With the support of the HTTP server Apache Tomcat 8, a server application has been developed. The application is built as a Java servlet, containing all necessary methods to retrieve and send data between the client and the database. The database is a relational database built in MySQL and supports transactions. The client consists of the mobile phone application written for Android based mobile phones. With the help of Orcad CIS and PCB editor, a scheme and a layout has been made for the product. The hardware was programmed with the help of an USBasp in avr gcc, which is a well fitting environment in C language for AVR microcontrollers.
