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 and watches, Smart homes, Smart irrigation systems, Smart cities, etc. To start learning IOT, first, it is important to learn about the things that are needed to make circuits. There are some simulators available to make the beginner of IOT learn these concepts without even having the IOT devices available. ... 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 connected to microcontrollers such as ESP32 or Arduino and can be used by programs to read the values. In this article, using two different examples, the use of DHT11 and DHT22 Sensors is demonstrated using ESP32. The circuit is made using ESP32 microcontroller and DHT sensors in actual and on ...

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 easy-to-use interface to design dashboards. The key for authentication can be generated directly from the user’s account and can be included in the program to connect the IOT components to the respective dashboard. The feeds are important to make connections, using the program that connects the IOT circuit to the ... 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 IOT learn such concepts without even having the IOT devices available. However, to get real results, using the circuit components and making the actual circuit is important. In this article, using two different examples, the way to use the RGB led is given. In example 1, the actual circuit using ... 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 IOT devices available. However, to get real results, using the circuit components and making the actual circuit is important. In this article, using two different examples, the way to start IOT programming is given. In example 1, the Wokwi simulator is used and in example 2, the actual circuit using ... 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 of a servo motor. Wokwi simulator is software that can be used for running the code and virtually testing the results without buying the components. The actual diagram of the components is often different from those used in Wokwi, so the actual form of the slider potentiometer is given in ... Read More

A simple buzzer can be connected to the ESP32 controller for producing sound. It can also be used to produce melodies. In this article, using two different examples, the C code is used on Arduino to make the buzzer play the melody. In the first example, “Twinkle Twinkle Little Star”, the poem’s notes are played and in the second example, another famous poem “Jingle Bell” is used for playing the note while making two colored LEDs on and off to create a light show with music. Example 1: Playing the poem notes using buzzer and ESP32 The circuit is made ... Read More
