Interfacing Ultrasonic Sensor HC-SR04 with Arduino Uno R3

Here we come with the topic Interfacing Ultrasonic Sensor HC-SR04 with Arduino Uno R3. After getting the interfacing successfully lots of projects window will be open for us. In my earlier post we saw that how to interface LM35 analog temperature sensor with Arduino at “Arduino based digital thermometer”. So to know the Interfacing Ultrasonic… Read More »

Arduino based digital thermometer

Here we see arduino based digital thermometer. So we are in very first step forward toward analogue sensor interfacing with arduino. Thermometer basically is a temperature measuring instrument. By using this project “arduino based digital thermometer”, we can measure the atmospheric temperature. This atmospheric temperature may use as an input of lots of advanced projects.… Read More »

Smartphone controlled LED using arduino uno

We come with a new and very useful project tutorial of smartphone controlled LED using arduino uno. It is somewhat we called first step of wireless communication. Smartphone controlled LED using arduino uno is an application of Bluetooth interfacing with arduino uno board. Before start the project I request if you have any doubt on… Read More »

Interfacing HC-05 bluetooth module with arduino uno

Interfacing HC-05 bluetooth module with arduino uno is a best way to serial communication with other Bluetooth unit. We know any data can be transmitted by serial communication through HC-05 bluetooth module. For that we have to connect HC-05 bluetooth module with arduino uno board via UART port. So before entering the project discussion if… Read More »

Store data to mysql server from MIT App Inventor using php

Today in this post, we will see how we can Store data to mysql server from MIT App Inventor using php. It is very important because after getting the knowledge the process of Store data to mysql server from MIT App Inventor using php, we can implement it in various project like register and login… Read More »

Interfacing LCD with arduino Uno

Interfacing LCD with arduino Uno is an easy but very necessary task. Here we will see how to display some simple test to display in our lcd like our website name NBCAFE. For that we have to know two things hardware connection and necessary Arduino code for that. First we should know different pin of… Read More »

Arduino traffic light controller

Here we will see how easily we can made simple project Arduino traffic light controller. We use two traffic light board to control traffic in a one way junction. Let suppose in our junction car can only go in one direction that means east to west or south to north. That is why we place… Read More »

What is arduino uno ?

Before start working with arduino, first we have to know what is arduino uno ? Arduino is a microcontroller platform by using that we can captured the imagination of electronics enthusiasts. It is very easy to use and because it is open source nature make it a great choice for anyone wanting to build electronic… Read More »
