Temperature Controlled Fan using Arduino

Temperature Controlled Fan using Arduino

Here we are going to make a temperature controlled DC fan. DHT22 sensor is used to sense the room temperature and then we adjust speed of a DC fan/motor accordingly using PWM (Pulse Width Modulation). Arduino Uno is the heart of this project and a L293D driver IC is used to drive the DC fan/motor. Components Required Arduino Uno L293D Motor Driver IC DHT22 Sensor 16x2 LCD Display DC Fan/motor 9V Battery 10KΩ Potentiometer 220Ω Resistor Breadboard Circuit Diagram Temperature Controlled Fan using Arduino -...

Weather Station using Arduino - Web Server - IoT

Arduino Weather Station Web Server

In this tutorial we are going to make a weather station that will tell us temperature, humidity and heat index of a particular location. It will show these values in a web browser. You can monitor these data by entering the IP address in a mobile, computer or any other device which supports a web browser. This project is done using Arduino Uno, ESP8266 and DHT22 sensor. DHT22 sensor will read temperature and humidity information. ESP8266 WiFi module is used to establish network communication. Arduino is...

IoT Data Logger using Arduino and ESP8266

IoT Data Logger using Arduino and ESP8266

Today we are going to make an IoT WiFi data logger using Arduino, ESP8266 WiFi module and DHT22 temperature humidity sensor. Arduino is reading temperature and humidity sensed by DHT22 and sending it to an internet server using the ESP8266 WiFi module. Here we are using ThingSpeak as the internet server. ThingSpeak is an open source IoT application which can be used as an Internet or Intranet Server. It is providing HTTP API for data logging, location tracking, status updates etc. Components Required DHT22...

Home Automation System using Arduino and ESP8266

Home Automation using Arduino and ESP8266 Module

In this project we are going to make a home automation system using ESP8266 WiFi module and Arduino Uno. Using this we will be able to control lights, electric fan and other home appliances through a web browser using your PC or mobile. These AC mains appliances will be connected to relays which are controlled by the Arduino. ESP8266 and Arduino together acts as a Web Server and we will send control commands through a Web Browser like Google Chrome...

Digital Door Lock using Arduino

Digital Door Lock using Arduino

As thefts are increasing day by day security is becoming a major concern nowadays. In this project we will make a digital door lock system with keypad using Arduino Uno. It will open your door only when the right password is entered and it will start beeping when a wrong password is entered. Components Required 4x4 keypad LCD Arduino Uno Push Pull Solenoid TIP 120 NPN transistor Power Supply Breadboard 1KΩ, 220Ω Resistor 10KΩ Potentiometer Buzzer Connecting wires Circuit Diagram & Explanation Digital Door...
