This project provides a simple code to operate a GSM module with an Arduino board. The project aims to offer an easy and quick way to start using GSM modules in Arduino projects, such as sending and ...

This will help the Arduino to listen to the GSM module. When a call arrives to the GSM module the Arduino will listen to it and ask the GSM module to answer the call. The Arduino makes sure that the ...

In this project, the author is going to construct a system using a Arduino Development board and GSM module. He connects a switch/sensor to the Arduino board along with the GSM module. The user ...

As shown in Fig. 1, Arduino Board 1 and GSM module get ground connection through transistor TIP142 (T1). Also, very little drive current (<5mA) is required from Board 1. A 12V, 2A regulated power ...

This project uses GSM Module (SIM900) with Arduino to switch Relay state by SMS OR CALL. Step 1 (Connect SIM900 With Arduino) Use picture as a reference for connecting SIM900 to Arduino.

SIM800L Module Pinout. The SIM800L module is a GSM/GPRS module that offers a wide range of functionalities. It resembles a small chip with an antenna connector and various pins. The below image shows ...

The heart of this project is Arduino Uno which is the microcontroller used in this project. The PIR sensor will sense any motion in the range of 6 meters and if the motion is detected, it will send a ...

This project deals with the design & development of a theft control system for home, ... arduino gsm security alarm. ... // RX and TX pins to communicate with GSM module #define msg_key 7 #define call ...

An Arduino is equipped with a piezo sensor to detect impact, and a GSM shield takes care of the texting. It’s an interesting concept, similar to requiring police officers to wear body cameras.
