Summary of Call and Message using Arduino and GSM Module
This project demonstrates building a simple mobile phone using Arduino Uno and a GSM Module SIM900. The phone can make and receive calls, send and read SMS, and includes a microphone and speaker for voice communication. Inputs are handled through a 4x4 alphanumeric keypad, while a 16x2 LCD displays messages and alerts. The GSM module interfaces with the network, enabling basic phone functionalities. This setup is ideal for understanding GSM module integration with Arduino for telephony purposes.
Parts used in the Simple Mobile Phone using Arduino:
- Arduino Uno
- GSM Module SIM900
- 16x2 LCD
- 4x4 Keypad
- Breadboard or PCB
- Connecting jumper wire
- Power supply
- Speaker
- MIC
- SIM Card
Sometimes people find it difficult to use the GSM Module for its basic functions like calling, texting etc., specifically with the Microcontrollers. So here we are going to build a Simple Mobile Phone using Arduino, in which GSM Module is used to Make the Call, answer the Call, send SMS, and read SMS, and also this Arduino phone has Mic and Speaker to talk over this Phone. This project will also serve as a proper interfacing of GSM Module with Arduino, with all the Code needed to operate any Phone’s basic functions.
Components Required:
- Arduino Uno
- GSM Module SIM900
- 16×2 LCD
- 4×4 Keypad
- Breadboard or PCB
- Connecting jumper wire
- Power supply
- Speaker
- MIC
- SIM Card
Working Explanation:
In this Arduino Mobile Phone Project, we have used Arduino Uno to control whole system’s features and interfacing all the components in this system. A 4×4 Alphanumeric Keypad is used for taking all kind of inputs like: Enter mobile number, type messages, make a call, receive a call, send SMS, read SMS etc. GSM Module is used to communicate with the network for calling and messaging purpose. We have also interfaced a MIC and a Speaker for Voice Call and Ring sound and a 16×2 LCD is used for showing messages, instructions and alerts.
Alphanumeric is a method to enter numbers and alphabets both by using same keypad. In this method, we have interfaced 4×4 keypad with Arduino and written Code for accepting alphabets too, check the Code in Code section below.
