| Video Discription | A model 250A field telephone has been modified to work as a mobile telephone, using an Arduino Uno microcontroller and a SIM900 GSM shield. Any other old dial telephone can be converted in the same way. The Arduino monitors three switches using digital input pins. The cradle switch determines whether the phone is in transmit or receive mode. The dial switch operates when the dial returns, the number of openings being equal to the digit dialled. The call button passes the dialled number to the SIM900 and initiates the call. fEoDGGnNtCI |
