The microcontroller and the coding is the heart of making a timer. The strategic release planning is gotten from the concept of how a door machine with password access functions. In this thesis project, all that has been studied in school such as circuit theory, electronics, digital design and microprocessors basic and programming course are combined to the success of this project. Therefore the objective is producing a practical knowledge of what has been studied which is the timer with password access. The method used was an inspiration gotten after reviewing many materials in some respective topic related to designing a timer. The particular method comes from creating an SPI Interface from the Programmer to the Microcontroller to Make Transferring More Convenient. The performance of the MCU, LCD and keypad was just as was expected in the software code and hardware also. The password is inputted, timer is set appropriately and timer runs till port is opened. To conclude, the result can be achieved in different method but this method was for an easy method for beginners. === 0764353558
