Abstract

At  the  present  article  we  refer  to  the  pedagogical  use  and the construction of an experimental device whose cost is minimum to measure periods, specifically of a simple pendulum. In this case the low-cost instruments are  available to the teachers at schools. Its operation is similar to the Photogate, an electronics device that contains  emission  and  reception  of  infrared  light.  The  new suggested device changes light into sound during its operation so we denominated it, Soundgate.
