The MICO DTMF shield has a built-in signal amplifier that lets you measure the amplitude of the input signal in a provided sample sketch. The HT9200A tone generator is designed for MCU interfaces. By varying the resistance of the input device you vary the amount of resistance that completes the circuit, and in so doing you vary the frequency—or pitch—of the oscillator. In order to play digits such as DTMF, the tone generator is equipped with digit map, which contain information about the frequencies of the digits. On execution, the python script will dial the number stored in  “ PHONE_NUMBER ” variable and once this phone goes off-hook, it will pass the DTMF digits stored in “ DTMF_DIGITS ” variable. Generate and plot a DTMF signal for each button on the telephone pad. We can use a Python timer to start a timer if we're finished playing sounds and we got to the end of the sound prompt list.
