The success of therapeutic treatments, especially for chronic conditions, is essentially based on medication adherence. This paper focuses on the design and implementation of a low-cost automated medication dispenser, with the purpose of improving treatment adherence and patient support. The system consists of a mechanical module, 3D-printed and controlled by an Arduino microcontroller, with a mobile application developed in MIT App Inventor. The dispenser automatically rotates and releases doses at preset times and also provides visual and auditory alerts to the users of the application. The data on medication intake is stored locally and can be transferred via Bluetooth connectivity. The solution is compact, easy to use and significantly more affordable compared to similar commercial devices, with a low price of approximately 50 Euros. Experimental results showcase the system’s efficiency, making it effective for both individual patients at home and potential large-scale use in healthcare facilities.
