This library reads the signals of the MT8870 chip. If data is available one can read it raw or as text. DTMF = Dual Tones Multiple Frequency. These are the tones you hear when you press buttons on ...
[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 ...
Calling all electronics tinkerers and hobbyists! This is a brand new MT8870 DTMF (Dual-Tone Multi-Frequency) decoder module. In simple terms, it's the chip that converts the tones from a telephone ...
int STQ = 3; // DTMF Module STQ Pin connects to Arduino Digital Pin 3 int Q4 = 4; // DTMF Module Q4 Pin connects to Arduino Digital Pin 4 int Q3 = 5; // DTMF Module Q3 Pin connects to Arduino Digital ...
