Machine learning (ML) is becoming increasingly important for microcontrollers because it enables smart and autonomous decision-making in embedded systems. The many Internet of Things (IoT) applications — often called “smart devices” — only become intelligent thanks to ML. Microcontrollers are commonly used in edge computing devices where data is processed locally rather than being sent…

The Internet of Things (IoT) is a network of billions of smart devices working with countless Internet-enabled digital services. One such service is weather forecast. Weather APIs integrate weather data with smart devices, websites, and online platforms. Several IoT applications use weather data, such as smart clocks, temperature control systems, as well as travel and…

Nowadays, most of the hotels and restaurants take online orders of food. Many hotels and restaurants either facilitate pre-ordering or even render delivery services in the local areas. In this project, an Hotel Order Management System is designed where a customer can pre-order food items using a mobile app and a Raspberry Pi based Server manages to cater menu items and book orders.

In the previous tutorial, it was mentioned that IMAP protocol is a standard email protocol which is used to store email messages and retrieve them. It was also mentioned that IMAP protocol can be used in IoT applications where commands can be passed to IoT devices by emails. This can be really helpful in certain situations like when security might be the main concern. Also, emails can be sent on any network without any special application or permissions. The IoT devices can receive emails as email clients where they can read emails and process information contained in them.

It was mentioned that WSN can utilize many wireless standards and protocols to enable sensor communication with a cloud or server. It was also mentioned that wireless sensors communicate to a cloud or server with the help of a Gateway which performs protocol conversion for the wireless network. Zigbee is one of the standard and protocol which is generally used for WSN deployed in industrial applications.  

In today’s digital world, machine-to-machine (M2M) is quickly becoming standard. M2M includes any technology that enables networked devices to exchange data or information. It can be wired or wireless, but the Internet of things (IoT) has made such wireless communication between devices commonplace. The interconnected of things has also made these devices intelligent. Consider how…

In the previous tutorial, Zigbee technology and its application in building Wireless Sensor Networks was discussed. In this tutorial, learn to perform simple Client to Client Communication over Zigbee Protocol. There will be two Xbee modules taken and will be configured to communicate data with each other over the air. The Xbee devices communicate with each other wirelessly over the air. They do not have any microcontroller or processor in themselves, so they cannot manage the received or sent data.

In the previous tutorial, communication between two PCs was setup over Zigbee Protocol using Xbee modules and XCTU software. In this tutorial, two Xbee module based IoT devices will be designed and configured to communicate with each other over Zigbee protocol. One of these devices in the Zigbee network will be a Coordinator device and the other will be a Router device. The coordinator device will control LED interfaced at the Router device. 

In the previous tutorial, IoT communication between two devices over Zigbee protocol was demonstrated using two Xbee modules. The two modules were communicating with each other automatically without any human intervention. The two modules were also operating in transparent mode in the previous project.  In this project, an LED light controller is designed where one device controls the LED interfaced at other by communicating data in API mode. In this tutorial, two Xbee module based IoT devices will be designed and configured to communicate with each other over Zigbee protocol

In the previous tutorial, advantages of UDP protocol over TCP/IP in IoT applications were discussed. The UDP protocol has a small overhead of 8 bytes which makes it more suitable for use in the Internet of Things. In this project, the application of UDP protocol in IoT will be demonstrated. In this project, an ESP8266 Wi-Fi modem will be configured as UDP server and a laptop will be used as UDP Client.  

In the previous tutorial, advantages of CoAP protocol over TCP/IP and UDP protocols in IoT applications were discussed. The CoAP protocol is specially designed for constraint devices and networks. In this project, the application of CoAP protocol in IoT will be demonstrated. In this project, an ESP8266 Wi-Fi modem will be configured as CoAP server and a laptop will be used as CoAP Client. Both Client and server will be co-located communicating through same Wi-Fi router so, the ESP board will act as a local server. The CoAP Client could send data to the server on a particular port with the help of browser add-on – Copper (Cu) CoAP user-agent. In fact, the Copper (Cu) itself will act as CoAP Client.

Device to Device Communication has a great role in IOT. In context to IOT systems, this device to device communication usually voids human interaction and control over the devices and the devices are meant to communicate with each other autonomously. In this tutorial, a similar demonstration of Device to Device Communication is presented.  

In the previous tutorial, the basics of Ethernet technology were discussed. In this tutorial, the Ethernet technology will be used to connect an Arduino board over internet with a PC.
