In this tutorial, we will learn how to use an RIR motion sensor with Raspberry Pi Pico and configure external interrupts of Raspberry Pi Pico using MicroPython. We will demonstrate the use of external interrupts through an example with a PIR motion sensor and an LED. Recommended Components The following components are used in this … Read more
In this tutorial, we will learn how to interface PIR Motion Sensor with Raspberry Pi Pico and use GPIO pins of Raspberry Pi Pico as output pins as well as input pins. Accordingly, we will also show how to control an LED via a PIR motion sensor with a Pi Pico board. We will be … Read more
In this tutorial, we will build an IoT based motion detection project using an HC-SR501 PIR motion sensor, ESP32 with an email alert feature. Our motion detection project will be linked with a web server that will update whenever motion will be detected, specifying the exact date and time of the detection. Additionally, we will … Read more

Our motion detection project will be linked with a web server that will update whenever motion will be detected, specifying the exact date and time of the detection. Additionally, we … Read more
In this tutorial, we will learn to use interrupts and timers of ESP8266 NodeMCU using Arduino IDE. By using ESP8266 interrupt, we will be able to detect changes on GPIO pins without the need to continuously poll GPIO pins. Whenever an interrupt occurs, we can execute a certain function that should execute on state change … Read more
This tutorial focuses on an example project which shows motion detection through a PIR motion sensor. This PIR motion sensor will be interfaced with the ESP32 board and a 5mm LED. Through interrupts and timers of ESP32, the LED will be controlled. Whenever motion will be detected, an interrupt will be triggered, a timer will … Read more
