Interfacing GSM Modem with Arduino - Practical Implementation

Interfacing GSM Module with Arduino

In this article, I am going to explain about interfacing of GSM Module with Arduino. Interfacing a GSM module to Arduino is pretty simple. We have to make only 3 connections between the GSM module and Arduino. For the working demonstration we will be sending an SMS to a particular number whenever a switch is pressed. Components RequiredArduino Uno GSM Modem Switch 1kΩ Resistor Breadboard Connecting WiresHardware Circuit Diagram Interfacing GSM Modem with Arduino – Circuit Diagram ConnectionsConnect TX pin of GSM Module to RX pin of Arduino Uno. Connect RX [...]

Interfacing Moisture Sensor with Arduino

Interfacing Soil Moisture Sensor with Arduino

Introduction In this article, we are going to interface a Soil Moisture Sensor with Arduino Uno. We will measure the moisture content of soil in pot or farming field and by using this we can pour water into field based on preset values. This sensor measures the volumetric content of water inside the soil (based on resistance/conductivity) and gives the moisture level as output. The sensor is equipped with both analog and digital output, so it can be used in both [...]


Interfacing Rain Sensor with Arduino

In this article we are going to explain about interfacing Rain Sensor with Arduino. The rain sensor module is an easy tool for rain detection. It operates as a switch when raindrop falls through the raining board and also it measures rainfall intensity. The module features, a rain sensing board and the control board that is separate for more convenience, power indicator LED and an adjustable sensitivity though a potentiometer. Rain Sensor Module Raindrop sensor is basically a board on which [...]

PIC Microcontroller - SPI

SPI Communication with PIC Microcontroller – MPLAB XC8

SPI (Serial Peripheral Interface) is a full duplex synchronous serial communication interface used for short distance communications. It is usually used for communication between different modules in a same device or PCB. SPI devices communicates each other using a master slave architecture with a single master.SPI CommunicationSPI is called as a 4-wire bus as it requires four wires for its communication as shown above. In the case of single slave communications we need only 3 wires, as slave select (SS) [...]
