The Intelligent Sejadah serves as a solution to the common problem of forgetting the number of rakaat (prayer units) during prayers, while also fostering discipline among children in their prayer routine. This innovative device operates by accurately counting the rakaat and providing real-time feedback each time the prostration movement occurs. By considering each set of two prostrations as one rakaat, the device increments the rakaat count accordingly, ensuring accuracy and convenience for the user. Moreover, the rakaat count can be conveniently relayed to a mobile application via the NodeMcu ESP8266, enhancing accessibility and monitoring capabilities. The circuit components, meticulously selected and simulated using Tinkercad software, include an ultrasonic sensor (HC-SR04) for prostration detection, a 7-segment display for visual indication of the current rakaat count, and an I2C LCD to display the type of solat performed during prayer. Additionally, a pushbutton is incorporated to reset the counter if inadvertently activated before the start of the prayer session. The entire circuit is orchestrated by an Arduino Uno and ESP8266 NodeMCU controller, ensuring seamless integration and efficient control. Through diligent design and simulation using Proteus Software for PCB layout, the project has successfully realized its objectives, offering a reliable and user-friendly solution to enhance the prayer experience and instill discipline in individuals' prayer routines.
