Interfacing Sim800l With Arduino

Step 2 Interfacing SIM800L With Arduino Uno Use a voltage divider to shift the Arduino Uno's 5V logic levels to the 3.3V required by the SIM800L module. Create a voltage divider circuit using a 10k resistor and a 20k resistor connected in series between the Arduino's TX pin transmit and the SIM800L's RX pin receive.

The SIM800L module is a GSMGPRS 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 sim800lpinout, this will later be useful when we are connecting the sim800l gsm module with Arduino.

To solve this problem, we'll use a simple voltage divider made of resistors Connect a 10K resistor between the Arduino's 2 pin and the SIM800L's Rx pin. And connect a 20K resistor between the SIM800L's Rx pin and GND ground. This setup safely reduces the 5V signal from the Arduino to about 3.3V that the SIM800L can handle.

Note don't forget to connect ground first then other connection with your Arduino to avoid module damage or make all connections first then power-up the circuit.

In this tutorial, we will show you how to interface the SIM800L with an Arduino. What You Will Need. SIM800L GSM Module Arduino Board e.g., Uno, Mega, Nano Breadboard Jumper Wires SIM Card unlocked and with creditdata plan Power Supply capable of providing 3.7V-4.2V for the SIM800L

SIM800L Module Pinout. The SIM800L module is a GSMGPRS 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 sim800lpinout, this will later be useful when we are connecting the sim800l gsm module with arduino.

Arduino UNO SIM800L One 8 ohm speaker One microphone The power supply of 5 volts and 2A Breadboard Jumper wires Pin connection of SIM800L GSM GPRS module with Arduino UNO. Connect an antenna to the Antenna pin. Connect the VCC pin of the module to the positive terminal of the external power supply.

SIM800L Interfacing with Arduino Uno Now you are all set to play with Sim800l. After interfacing, when you power this module, you will see that the onboard LED is on and blinking in different patterns. This blinking pattern of the onboard LED tells us the working status of the SIM800l module.

SIM800L Interfacing with Arduino Uno. Now we know everything about the module,lets start interfacing it with the Arduino. To begin, solder or connect the antenna, then insert a fully active Micro SIM card into the socket. As we'll be utilizing software serial to communicate with the module, connect the Tx pin on the module to digital pin3 on
