Summary of Call and Message using Arduino and GSM Module
This article describes building a simple mobile phone using an Arduino Uno and SIM900 GSM module. The project enables calling, answering calls, sending/receiving SMS, and voice communication via a microphone and speaker. A 4x4 keypad handles input for numbers and text, while a 16x2 LCD displays messages and alerts. The system demonstrates full GSM interfacing with Arduino for basic telephony functions.
Parts used in the Simple Mobile Phone:
- 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.
