In this Arduino tutorial, we are going to learn how to use a motion sensor to sound a piezoelectric buzzer. The motion sensor used here is a PIR se...
In this tutorial, we are going to learn how to build an IoT based Home Security system using the NodeMCU ESP8266 module and Adafruit IO. In this project, we will learn about how to use the Adafruit IO platform to record, analyze, and control the live data on the cloud.
