How to Build a DIY Music Player with Arduino Nano and SD Card Reader

Harsh Sehgal 0 Comments

In this project, we will building a music player using an Arduino Nano and SD card reader. The music player will be capable of playing MP3 files stored on an SD card in wave form and we will have basic controls for play, pause, forward and backward. The project is a great introduction to...

Design and Implementation of a Traffic Light Control System Using NE555 IC

Harsh Sehgal 0 Comments

The NE555 timer is a versatile electronic device used in circuits to create timing functions. In this project, we will use it to simulate a traffic light using LEDs, with the circuit consisting of three LEDs representing the colors of the traffic light: red, yellow, and green. The NE555 timer will be used to...

Wireless Communication: Interfacing 433MHz Transmitter and Receiver Modules with Arduino UNO

Harsh Sehgal 0 Comments

A 433MHz transmitter and receiver pair uses Amplitude Shift Keying (ASK) modulation to transmit and receive data wirelessly. The transmitter modulates a 433MHz carrier wave with the data signal using an ASK modulator, and transmits the modulated signal through an antenna. The receiver picks up the transmitted signal with an antenna, filters out unwanted...

DIY Temperature and Humidity Monitoring System with Arduino and DHT22 Sensor

Harsh Sehgal 0 Comments

In this article, we will learn about how we send temperature and humidity data from a DHT22 sensor and displays it on an LCD screen using an Arduino board. The LCD screen is initialized with its pins and dimensions, and the temperature is printed in Celsius or Fahrenheit depending on the value of a boolean...

Arduino Based Light Following Robot with LDR Sensor
