Abstract :
This paper presents the design and implementation of a laboratory experiment for first year undergraduates of Bachelor of Science or Engineering degrees. The aim of the experiment is to consolidate concepts related to the subject of Physics. The laboratory experiment involves measuring the period and frequency of oscillation of a simple pendulum by means of an electronic device based on the PIC 18F4550 microcontroller, which handles the data acquisition and processing. The student will discover that for small angles, the period for a simple pendulum does not depend on the mass or on the initial angular displacement, but only on its length and on the value of the gravitational field strength (g), the latter being one of the parameters to be indirectly determined with this experiment.
