Topic: Connecting Arduino and Cell Phone (Read 396 times) previous topic - next topic


Hello, I have made a SONAR by HC-SR04 & Servo and I want to use it for security reasons in my house.

I want the Arduino to call my cell phone whenever it detects and obstacle as shown in the image.

How can it be done? I will keep searching till someone helps me. Thanks in advance.


First you should write a program which just detects obstacles and sends a message to Serial monitor. When you have that working post it here.

Getting it to send a message to a cell phone will use a GMS module like a SIM 900. It will not be difficult to add this to the basic obstacle detection program. There are many examples around.
