The project consists of an arduino uno, a GSM shield, a bluetooth shield, a battery pack, an on switch, and an off switch.
I want to make a simple device that calls a phone number when a device connected via bluetooth leaves the range of the shield (~36ft). The device should also automatically connect to the bluetooth device as soon as it enters the range.
I also want the device to send a text message to the phone number when the battery is low.
I have all of the necessary parts and connectors, and just need a bit of help with the programming. I may also need help with the schematics.
So, Again, I want one Arduino connected to a phone via bluetooth. Once the phone leaves the bluetooth range of the Arduino, I want the Arduino to give the phone a call alerting it that it left the range. Thanks.
