The most modern way to live in the 70s, 80s, and 90s, a phreaking awesome Blue Box DTMF tone generator
DTMFDuino receives DTMF tones through a MT8870 integrated circuit who converts the analog audio of tones to a binary code understandable by the microcontroller. The microcontroller runs Arduino bootloader and converts the received codes to actions (turn on and off some outputs), also the system has the option to know the current state of each output.
