Remote Control Tester Hardware

The purpose of this project is to build a device that can capture the Infrared (IR) signal transmitted by all types of remote controls. It can capture IR codification signal at the modulation frequency level. This device not only simply captures IR signal, it also can decode this IR signal. Telling us what codification is […]
