Radio Remote Control Using DTMF


Posted on Feb 4, 2014

This circuit is a circuit diagram of a remote control using DTMF. Actuality we achieve the use of DTMF (dual tone multi-frequency) signals (used the phone to punch in numbers) as the influence of the code. DTMF tones used for the abundance accentuation of the carrier. At the receiver, this abundance articulate intercepted signal to access a DTMF tone in the terminal apostles. Capturing DTMF is affiliated to the DTMF-to-BCD BCD is used to advocate achievement to switch-on and switch-off various e.
