Development of Smart Electromechanical Clock

The main topic of this paper is the design and implementation of a smart clock using an Arduino control board. The clock contains sensors and two additional modules. One of them is the Bluetooth module, which provides a wireless connection between the phone and the Arduino. The other accessory is the RTC (Real Time Clock), used for time measurement. A phone application has been created to set the exact time and display the values of the sensors in real-time. An electromechanical display has been designed instead of a traditional display. Digits are displayed by moving the segments with the servo motor. The clock was manufactured using 3D printing technology.
