ESP8266 Based Webserver to Control Servo Motor from Webpage

In this project, we are controlling a Servo Motor using a web browser with the help of Arduino and ESP8266. ESP8266 wi-fi modules is a cheap and powerful device, helps in communicating with any microcontroller, like here Arduino UNO.

Arduino Obstacle Avoiding Robot

Arduino Obstacle Avoiding Robot

In this DIY project, we use Arduino and Ultrasonic Sensor to build an Obstacle Avoider. Here an Ultrasonic sensor is used to sense the obstacles in the path by calculating the distance between the robot and obstacle. If robot finds any obstacle it changes the direction and continue moving.

Arduino LoRa Tutorial

Arduino LoRa Tutorial

As ESP modules become synonyms for Wi-Fi applications, this LoRa technology also has caliber to build a vast network like Internet. We previously build many IoT Based projects using ESP8266 and Arduino, here in this article we will learn about LoRa and how to use it with Arduino Development Platform.

XBee Module Interfacing with Arduino

XBee Module Interfacing with Arduino

In previous tutorials we have learned about ZigBee protocol and its architecture, and also learned about wireless communication between two Xbee modules. Now in this tutorial we will interface XBee module with Arduino Uno board. The XBee connected with Arduino board will act as a receiver and it will communicate wirelessly with other XBee module which is serially connected with the laptop using a Explorer Board. So lets explore further for Arduino wireless communication using XBee.

How to Use SPI Communication in STM32

How to Use SPI Communication in STM32

In this STM32 SPI Example, we will use Arduino UNO as Slave and STM32F103C8 as Master with Two 16X2 LCD display attached to each other separately. Two Potentiometers are also connected with STM32 (PA0) and Arduino (A0) to determine the sending values (0 to 255) from master to slave and slave to master by varying the potentiometer.

Arduino I2C Tutorial

Arduino I2C Tutorial

In this Arduino I2C tutorial we will use I2C communication between two arduino boards and send (0 to 127) values to each other by using potentiometer. Values will be displayed on the 16×2 LCD connected to each of the Arduino.  Here one Arduino will act as Master and another one will act as Slave. So let’s start with the introduction about I2C communication.

Arduino SPI Tutorial

Arduino SPI Tutorial

In this tutorial we learn about SPI protocol and how to use it in Arduino. We will use SPI Protocol for communication between two Arduinos. Here one Arduino will act as Master and another one will act as Slave, two LEDs and push buttons will be connected to both the arduinos. To demonstrate SPI communication, we will control master side LED by the push button at slave side and vice versa using the SPI Serial communication protocol.

Arduino based Smart  Watch

Arduino based Smart  Watch

So here we fetch some information from an Android mobile phone by using an android application and then send this information to OLED display by using Bluetooth Module and Arduino Pro Mini. Android smartphone already has inbuilt Bluetooth to send the data and at receiving end we have used Bluetooth module HC-06 with Arduino. Bluetooth module HC-05 can also be used in place of HC-06.
