In this project, you will learn how to control different types of electrical loads “DC or AC” using the famous MT8870DE DTMF Tone Decoder IC. You can use this to control a robot, an airplane, electrical loads, etc, in real-time.Ī project based on the DTMF “Dual Tone Multi-Frequency” that I am about to share with you guys is one of my first top 20 projects I created when I just started learning Electronics. This can be used just like the Wireless Radio Transmitters and Receivers. While using the MT8870DE DTMF Decoder there is no need to write a message.
