This thesis aims to develop hardware for laboratory in courses such asSwitching Theory at Halmstad University which can help students tounderstand practical applications of the hardware they are studying atuniversity. To achieve this, a printed circuit board (PCB) that simulates trafficintersections has been designed, constructed, and tested.The project consists of four main phases. The first step is to create anequipment list to identify the components needed to meet our goals. Then, theschematic design phase is started using KiCad program for PCB design. Aprinted circuit board is manufactured, and all the components lists in theequipment inventory is carefully soldered. This step completes the secondstage, involving PCB fabrication and component placement. The next step isto program one intersection using an embedded system according to a statemachine and ensure the PCB works properly. For this purpose, a statemachine is developed to describe test conditions and program sequences.
