The study designed a device as an aid for instruction in the Computer Engineering Laboratory. This also establishes the accuracy of the output of the simulator device and the reliability of its operation. Knowledge in hardware designing and programming in PIC Basic Pro had been employed to make the design of the simulator device. A PIC microcontroller served as the processing unit and several input/output devices were utilized for user interface. The cost of the construction of the prototype is Php 7,716.00 including the cost of labor. By carefully recording and tabulating the outputs of the device for several trials in a form of observation guides, relevant data had been gathered to validate its functionality and performance in terms of its intended use in the laboratory. The researchers concluded that the simulator device exhibited accurate results/outputs for up to five-variables in a function and four functions in every trial. The binary equivalent of the LED outputs, matched those in the truth tables in the manual computation. It is recommended that the functionality of the device be improved with the use of a more powerful microcontroller like the PIC 18fXXX series to provide higher memory and more I/O terminals.
