GSM Course with Arduino (SIM900A) (No Libraries)

Identify the hardware and software components used in this GSM course with Arduino. Explore the GSM module, TTL converter, Arduino board, and Arduino IDE, plus testing tools like Dock Clips.

Learn how to set up the Arduino IDE, use setup and loop, upload sketches, and use the serial monitor for displaying data and debugging with serial.begin(9600) and serial.print.

Configure an Arduino to blink the onboard lcd and an external led by defining pins, setting output mode in setup, and toggling in loop with a 500 ms delay.

Learn how to interface basic input devices with a microcontroller using pull-down and pull-up logic, including circuit setup with a 10k ohm resistor and a switch to Vcc or ground.

Interface a push button with an Arduino to light a led using pull-down and pull-up logic, configure pin modes, read digital input, and upload code to run on the Arduino.

Test basic AT commands for a SIM900A GSM module by configuring a DSM module with a TTL USB converter, and adjust baud rate and echo settings.

Learn to test network based AT commands on a gsm module, including sim presence checks, network readiness, echo control, signal strength, and automatic versus manual network configuration.

Learn to use the SIM card phone book in nonvolatile memory with AT commands, including CPBS, CPBW, and CPBR, to store and retrieve contacts.

Learn how to test call-based AT commands in GSM by dialing, answering, and terminating calls using a SIM card phonebook and stored contacts.

Learn to make and end calls with a SIM900A module using an Arduino, via software serial, sending AT commands, and push-buttons to dial and hang up.

Learn how to test SMS based AT commands in GSM by configuring text mode, sending SMS, reading inbox, and deleting messages using AT commands on a SIM900A module.

Learn to send sms with sim900a using arduino by triggering two messages via push buttons, using software serial and at commands to initialize the gsm module.

Learn to receive sms with the sim900a using arduino, parse the message content from the serial output, and control an lcd display based on the command content.
