For IoT projects, we need to use a microcontroller. ESP32 is one such microcontroller that can be used to start learning IOT and making IOT circuits. It is therefore important to learn about its pins layout and also what is the purpose of each pin and how it can be ... Read More

ESP32 microcontroller can connect to the internet and use the wifi. It can be used to see the network details of the available networks. It can also be used for advanced functions such as changing the MAC address of ESP32. In this article, using three different examples, the programs using ... Read More

NoSql databases are those databases that do not store the data as data is stored in relational databases. Most of the data that is used in real life is often unstructured. These NoSQL databases provide an easy way to store this unstructured data by using key-value pairs. In this article, ... Read More

IOT ie. The Internet of Things refers to all those devices that can communicate over the Internet and can be made accessible or connectable by anybody and from anywhere in the world. IoT is already being used or has been seen implemented in different forms such as in Smart cars ... Read More

DHT11 and DHT22 sensors are sensors that can be attached to a microcontroller on a breadboard and can measure the humidity and temperature of a place. The differences between these sensors are that DHT22 is more expensive, has better temperature reading ranges, and is more accurate. These sensors can be ... Read More

Adafruit.io is needed to display the IOT project’s data online in real-time. It is a cloud server that can be used to connect to IoT devices through wifi and to control these devices through a dashboard. It can be used as a free service and it has got a simple ... Read More

To learn about RGB led and the difference between single-color LEDs, it is important to make a circuit using a microcontroller such as ESP32 or Arduino and RGB led. Then it is important to manage that circuit using a program. There are some simulators available to make the beginner of ... Read More

To start learning IoT, first, it is important to learn how to make circuits using a breadboard and a microcontroller. Then it is important to control that circuit using a program. There are some simulators available to make the beginner of IOT learn both these concepts without even having the ... Read More

BMP180 sensor is a sensor that can be attached to a microcontroller on a breadboard and can measure the pressure, temperature, and altitude of a place. It can be connected to controllers such as ESP32 or Arduino and can be used by programs to read the values. In this article, ... Read More

In this article, using two different examples, the use of potentiometers is demonstrated using ESP32. In the first example, the trimmer type of potentiometer is used to vary the voltage between 0 and 3V. In the second example, the slider potentiometer is used on Wokwi Simulator to show the control ... Read More
