The thesis discusses the realisation, from the very beginning to the final working prototype, of the Personalised time alarm.
It describes the planning of the Personalised time alarm, the final electronic scheme of the printed circuit board and the drawing process of the printed circuit board with the help of the SprintLayout programme from the first to the final version that contains step by step corrections and improvements. This is followed by the presentation of the working principle of some of the inbuilt components and the reasons for their specific placement.
The step by step description of the prototype creation presents how the printed circuit board is copied on a copper surface, the process of etching, and the placement, attachment and binding of individual electronic elements on the board.
We continue with the explanation of the purpose and functionality of the Personalised time alarm, followed by the definition of the programme code illustrated with a flowchart diagram.
The final chapter discusses the testing of the Personalised time alarm prototype and the elimination of unexpected problems.
