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

How to use NodeMCU Module having ESP8266 with Arduino Software

This blog will demonstrate how to use NodeMCU (which is having ESP8266 module on it) with Arduino Software. I am assuming that before trying your hand on this tutorial, you might already have done the basic things on Arduino like Basics of Arduino, Blinking LED or LCD Display etc. If not, please go through those basic tutorial before moving forward. What is NodeMCU or ESP8266 ? The … Continue reading How to use NodeMCU Module having ESP8266 with Arduino Software

LCD Scroll Icon using Arduino

In this demo, I will show you how to make some icons like heart shape or any other kind of icons and scroll them on LCD display with Arduino Board using LiquidCrystal Library. LiquidCrystal Library is very powerful library and most of the functions are available in the library which can be called and used in the Arduino program. Before this, You must know the … Continue reading LCD Scroll Icon using Arduino
