Home Automation: Sound Alarm and LCD display when temp is above threshold using Arduino

This blog will demonstrate how to make a Home Automation System which will start sounding a alarm whenever temperature reaches more than the programmed threshold value. It will keep displaying the current temp of the room on the LCD and action needed (Ex: Decrease Temp) when temp reaches more than threshold value. In this tutorial, I am using AD22100 temp sensor which is manufactured by Analog … Continue reading Home Automation: Sound Alarm and LCD display when temp is above threshold using Arduino

Temp Sensor AD22100 Connection and Temp Display on LCD using Arduino

This blog will demonstrate how to connect a temp sensor to an Arduino board and observe the value on serial monitor and display the temperature value on LCD display connected to Arduino. In this tutorial, I am using AD22100 which is manufactured by Analog Devices. AD22100 is a Voltage Output Temperature Sensor with Signal Conditioning. It is having 3 pins. Before going further, I am assuming … Continue reading Temp Sensor AD22100 Connection and Temp Display on LCD using Arduino

Connecting a Magnetic Buzzer and LCD display to Arduino

In this blog, I will talk how to connect a magnetic buzzer on Arduino and make it sound. Just for making this project better, i have also connected LCD to it and displaying the message whether ring is happening or not. AC-1005G buzzer is being used for this demo. It will have operating voltage from 3.0 – 8.0 V. This kind of buzzer can be useful … Continue reading Connecting a Magnetic Buzzer and LCD display to Arduino

Accelerometer ADXL327 Sensor Communication with Arduino

This blog will demonstrate how to connect accelerometer sensor with arduino boards (Arduino UNO here) and communicate with them. In this tutorial, I am using ADXL327 which is an acclerometer manufactured by Analog Devices. The ADXL327 is a  3-axis accelerometer with signal conditioned voltage outputs. It’s output is an Analog voltage which is proportional to the acceleration. Before going further, I am assuming that you … Continue reading Accelerometer ADXL327 Sensor Communication with Arduino

Controlling LED from http webpage via WiFi using NodeMCU having ESP8266

This blog will talk about controlling of a LED from http webpage via WiFi which is connected to NodeMCU module having ESP8266 on it. This can be extended for home Automation at a large level.(How 😛 :P) Before going further, I assume that you already have a NodeMCU module with you and 1. you know how to use it with Arduino IDE (Click here to … Continue reading Controlling LED from http webpage via WiFi using NodeMCU having ESP8266

All LCD Functions using Arduino

If you are here on this site, that means you have started exploring Arduino Board and looking for some help with LCD display. You are exactly at the right place. In this demo, I will show you most of the LCD functions supported by LiquidCrystal Library with Arduino Board using one LCD display. Three LCD demos are already posted on my blog which you can … Continue reading All LCD Functions using Arduino

Setting simple HTTP web server using NodeMCU Module having ESP8266 and connect it with WiFi

This blog will demonstrate how to setting up a simple HTTP server on ESP8266 which is on Node MCU module and access the data sent by ESP8266 on HTTP webpage on any of the browser. Before going further, I hope that you already know how to make Arduino IDE identify the NodeMCU board and program this module by use of Arduino IDE Software. If  not, please … Continue reading Setting simple HTTP web server using NodeMCU Module having ESP8266 and connect it with WiFi
