[Colin] wanted a way to reliably control an Arduino via ham radio. One of the easiest methods of automated radio control makes use of Dual-Tone Multi-Frequency signalling. To those who aren’t into ...
The objective of the project is to decode dual tone codes into digits which are later interpreted by microcontroller. This device is very useful for decoding Dual Tone Multi Frequency (DTMF) generated ...
DTMF (Dual Tone Multi Frequency) is a signaling system for identifying the keys or better say the number dialed on a pushbutton or DTMF keypad. DTMF (Dual Tone Multi Frequency) is a signaling system ...
