Welcome to the world of Electronics

The Internet of Things (IoT) is changing the way we interact with our world, from our homes to our workplaces. One of the most significant impacts of the IoT has been in the area of home automation. With IoT-based devices, you can control and monitor your home's appliances from anywhere in the world, making your life more comfortable and convenient. In this article, we will look at how to build an IoT-based fan speed controller. This project is inspired from  IoT Based Smart Fan Control using ESP8266 and Blynk , you can check out before moving ahead. What is IoT-based Fan Speed Controller? An IoT-based fan speed controller is a device that allows you to control the speed of your fan using a mobile application or a web interface. The device consists of a microcontroller, a motor driver, and a Wi-Fi module. The microcontroller is responsible for receiving commands from the user and sending the corresponding signals to the motor driver, which controls the fan's speed. How to Build

Road accidents became a matter of concern due to the huge increase in traffic. The primary cause of accidents is due to the drowsiness of drivers in the nighttime. Fatigue and drowsiness are some of the leading causes of major accidents on Highways. The only solution to this problem is detecting the drowsiness and alerting the driver. So, in this project, we have thought of building a Driver Drowsiness Detection and Alerting System for Drivers using Arduino Nano, Eye blink Sensor, and RF Transceiver module. The basic purpose of this system is to track the driver’s eye movements using Eye blink Sensor and if the driver is feeling drowsy, then the system will trigger a warning message using a loud buzzer alert.

 How to use DRV8833 Dual Motor Driver Module with Arduino? The DRV8833 dual motor driver module is a useful device for controlling the speed and direction of two DC motors with an Arduino microcontroller. This module is a small but powerful device that can drive motors with up to 1.2A current per channel. It can also operate at a wide range of voltages, making it ideal for a wide range of applications. In this article, we will discuss how to use the DRV8833 dual motor driver module with an Arduino. Hardware setup  The DRV8833 dual motor driver module can be connected to the Arduino using the following pin connections: IN1 pin of the DRV8833 module to digital pin 9 of the Arduino IN2 pin of the DRV8833 module to digital pin 10 of the Arduino IN3 pin of the DRV8833 module to digital pin 11 of the Arduino IN4 pin of the DRV8833 module to digital pin 12 of the Arduino GND pin of the DRV8833 module to GND pin of the Arduino VCC pin of the DRV8833 module to 5V pin of the Arduino Once the DRV

 What do you know about NRF24L01 module? The NRF24L01 module is a low-cost, low-power, 2.4GHz transceiver module that is commonly used for wireless communication between microcontrollers, computers, or other similar devices. It was developed by Nordic Semiconductor and is widely used for applications such as home automation, remote control systems, and robotics. The NRF24L01 module operates in the 2.4GHz ISM (Industrial, Scientific, and Medical) band and has a data rate of up to 2 Mbps. It supports a number of data transmission modes, including shockburst, which allows for fast and efficient data transfer. The module has a range of up to 100 meters in open air and can be easily integrated with microcontrollers such as the Arduino and Raspberry Pi. One of the key advantages of the NRF24L01 module is its low power consumption, making it ideal for battery-powered applications. The module can be powered from 1.9V to 3.6V and has a power consumption of just a few milliamps during operation.
