This section covers electronics projects based on NodeMCU ESP8266 board. The NodeMCU is basically an open source firmware, and also commonly used term for the popular ESP8266 Development Board, which is a low cost, development board designed for IoT applications.
India has 16% of the world's population and only 4% of the world's water resources at its disposal. The situation is made worse by the fact that 70% of its water is contaminated. As a result, India ranks 120 among 122 countries on the Water Quality Index released by Water Aid. In India every year, 580,937,500,000 Litres of water is being wasted…
Gardening is a very relaxing hobby. However, due to our busy lifestyles, the plants in our garden may not always get the attention they deserve. What if we could monitor their condition from a distance and give them the care they needed? There is a Way! I aim to address this problem by integrating IoT with gardening. This way our garden becomes smart and…
ESP32 is really a powerful IoT device with built-in support for Bluetooth and WiFi. The ESP32 is an advanced version of its predecessor, the ESP8266, with extra features like RAM, ROM, GPIO Pins, etc. The ESP32 module supports both classic Bluetooth and Bluetooth Low Energy (BLE). The Classic Bluetooth can be used to transfer songs or files, and the BLE option can be used…
In the world of technology, Robots are one of the most fascinating things. In recent years, many technologies come across in the field of robotics and also many types of robots. In addition, we also made an interesting Robotic project, A IoT Robotic Arm. This Robotic arm is easy to use for automation. This IoT project…
Sometimes when we go out of our home for a few days. In this case, we cant give water to our favorite plants or we are busy with other works, so we forget to give water to our plants. Most of the time, we nearly forget about our plants in the mentioned cases. It’s hard to keep our plants alive. Because most of the indoor…
If you have a pet at your place and there is no one to feed him/her at the right time in your absence. So here we are building a IoT-based Pet Feeder which is simple, efficient, and economic. Using this automatic pet feeder, you can feed your Pet by using Blynk Mobile App or Web Dashboard from anywhere in the world. You just have to press a button or set a time and the rest…
The ESP32-CAM is a tiny board that comes with a camera, microSD card, and of course the ESP32 microcontroller for less than ten dollars. It also has Wi-Fi and Bluetooth capabilities making it an ideal choice for IoT projects. But working with the ESP32-CAM board can be an intimidating task because it requires an external programing board and it isn't as…
In this project, we are going to build a Smart Farming System using IoT. The objective of this project is to offer assistance to farmers in getting Live Data (Temperature, Humidity, Soil Moisture, and Soil Temperature) for efficient environment monitoring, which will enable them to increase their overall yield and quality of products. This smart agriculture using an IoT…
Sewage management is an important aspect of municipal infrastructure and undoubtedly, it affects our daily hygiene. Poor sewage/drainage management can cause urban floods which is most common in crowded cities. This problem can be addressed by using Smart Sewage Management Device based on IoT and Sensor Technology.
In this article, we are going to…
In 2019, Arduino Platform introduced Arduino Cloud IoT which is an end-to-end solution to help IoT enthusiasts and professionals in making connected projects easily. Arduino IoT Cloud provides a full-stack approach that is ready-to-use, by combining hardware, firmware, cloud services, and knowledge support needed to deliver an end-to-end IoT solution. This IoT Cloud…
I2S is an Inter-IC Sound protocol that is used mainly to transmit or receive the audio data in a synchronous serial port between two devices. There are many applications where audio communication is required in digital devices such as adding a microphone or adding a speaker output to play some audio.
There are multiple Audio protocols available in…
Analog radios are becoming extinct in this digital world since everything, from movies to songs, is being directly streamed from the Internet today. Let’s see how an Internet radio can be made by leveraging some simple digital electronics, coding, and an active Internet connection. Now, those who are following us regularly might already know that we have built a Raspberry Pi…
