This repository contains code and instructions for testing the SIM800C GSM module using an Arduino. The code forwards data between the serial monitor and the SIM800C module, allowing users to send AT commands and receive responses.

Unlock the potential of your Arduino projects with our comprehensive guide on using the SIM800C GSM module. This blog covers everything from an engaging introduction to step-by-step instructions on using the SIM800C. Learn about the essential components, detailed connection setup, and the necessary Arduino code to get your project running.

This circuit features an Arduino Nano microcontroller interfaced with a SIM800L GSM module and a 4-channel 5V relay module. The Arduino controls the relay channels via digital pins D4 to D7 and communicates with the SIM800L module through serial communication using pins D2 and D3.

Mar 19, 2019 · I am using an Arduino UNO to communicate with SIM800C(Link to SIM800C: Amazon.de : sim 800C gsm). In the attachment you can see how I connectet the modul to Arduino. You have to know I have a stable power supply of 5V 2A which is needed. To the TTL I connected 3.3V from a step down converter.

In this article, we will see how to interface Arduino with a GSM Module, and send SMS using the module. You will need the following −. Arduino board. A GSM Module (SIM800C, SIM900A, are popular examples, but you can have any other module as well) A GSM (2G) SIM Card, or a 4G SIM Card with 2G fallback option (Jio SIM Cards won’t work for ...

In this video, I will introduce you to SIM800C and SIM800L AT commands with Arduino Uno. Here I am using general-purpose AT commands that will run on almost ...

Now connect the LCD as shown in diagram and gsm module also. you can solder LCD on zero pcb. In gsm module the 5v and the GND will provided from arduino or external adopter.

Aug 22, 2022 · This is a Simple Homemade Phone using GSM Module and Arduino. This simple phone is capable of calling to another number as well as receiving an incoming call. Similarly, it can also be used to send an SMS as well as read a received SMS. So we have interfaced GSM Module SIM800/SIM900 with Arduino UNO Board.

Blynk+GSM Sim800+Arduino Uno+DHT11: Temperature monitoring have wide application in daily life. In modern day keeping an eye on temperature of places such as server rooms, hospital rooms, warehouses and green houses can help solve many problems. But …
