Security Alarm using HC-SR501 PIR Sensor and Arduino

Harsh Sehgal 0 Comments

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 sensor which stands for Passive Infrared Sensor. This is great for an intrusion detection circuit or burglar alarm circuit. Whenever the motion sensor senses movement the piezoelectric buzzer will...

A Complete Beginner guide: How to use MicroPython on ESP8266

Harsh Sehgal 0 Comments

One of the most common ways of coding ESP8266, working with it and probably the simplest is by using ArduinoIDE. It might also be known that ESP8266 does not need any changes to be made on hardware level for us to code it with ArduinoIDE. This means, that ESP8266 comes with inbuilt Firmware that...
