This project helps to contrlol facility with 4 different objects ,you may turn them on or off with your mobile phone.
Project based on Dallas micro controller and MT8870 DTMF decoder .
When you call to its phone number, controller counts number of rings and after circuit "answers" you.
You listen that line is busy and you can turn any device with your mobile phone .
F.e when you press "1" you phone send DTMF signal , project circuit detecst it and turns device 1 on. When you press 9 you end your call. Program for project written on C-51.
This project was very good job of Adi and Asaf.
