Can anyone help me to find circuit diagrams and resources for controlling devices through mobile phones. Or just how to utilize the ringing signal or the vibration to got a logical signal that can be used to subsequently control other circuits.
Hope to use old handsets examples because I don't want to buy modern and expensive handsets for experiments.
I prefer old Ericsson and Nokia.
And can I even utilize the LCD light when receiving a phone call to initiate a logic signal? What do I need in this case?
Thank you in advance.
