Distance Measuring with LED Notifier using HC-SR04 Ultrasonic Sensor and Arduino

Harsh Sehgal 0 Comments

In this tutorial, we are going to learn how to use ultrasonic sensor HC-SR04 interfacing with Arduino and measure the distance which will be notified by 7 LEDs. As we move closer to the sensor the  LED will glow consecutively and vice-versa.   HC-SR04 Ultrasonic Sensor Pinout The sensor has 4 pins. 5volts is...

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...

In this DIY electronics section, let’s make an electronics dice using Seven Segment Display (SSD) and Arduino Uno. This is a simple and fun to build project, and the good thing about this project is that it can be practically used to play games! So let’s get started with this fun project!   Working of the...

Interfacing GT511C3 Fingerprint Sensor with Arduino – Enrol and Detect Fingerprints

Quartz Components 0 Comments

In this article, we will discuss the GT511C3 finger-print sensor and how to interface it with Arduino. We will learn how to use the sensor with Arduino to enroll finger-prints on it and then detect the fingerprints whenever required. We will also show a red and green LED signal for verified and unknown finger respectively...

Arduino Music Player - Play songs from SD Card

Quartz Components 0 Comments

In today’s discussion we are going to discuss about an Arduino based music/audio player using micro SD card module and lm386 audio amplifier module. Using this Project, you can play, pause or change a song (audio file of a specific format) using an Arduino board. It’s going to more excited when you build this. ...
