Laplace Transform equation is greatly used to solve the differential equation. Laplace Transform has been an integral part of the Control System, Engineering Mathematics, and Signal and System syllabus. Although the importance of Laplace Transform is significant, it can be seen that the students are still struggling with this topic. This project aims to address this by creating a low cost and interactive electronic board that translate the models the electrical circuit to its Laplace domain. The objective of this project is to provide a student to an alternative software simulator for student to simulate the electrical circuit model. This educational kit helps students to obtain the transfer function of the system from the circuit via a tactile-based educational kit named Laplace Circuit Solver. The development of the teaching aid is explained extensively where the main component used is Arduino Mega while the output is display using TFT LCD screen. The flow of this project is firstly the user need to push the push button and the green LED will on. After that, the user should insert the component and the red LED will on. During that time, the buzzer will ring. After a moment, the green LED will turn on and the screen will display the equation. Finally, the equation displayed will follow the inserted component. The teaching aid is verified by testing all the possible scenario and the result indicates that the teaching aid produce the expected output.
