Arduino uses asynchronous serial communication to send-receive data to and from other devices. Arduino Uno supports serial communication via on-board UART port and Tx/Rx pins. Generally this transmission happens at 9600 bits per second which is termed as baud rate.
Arduino pushbutton example shows how to read a pushbutton with Arduino Uno. Pushbuttons (also spelled push-buttons) are widely used in calculators, phones and appliances. It closes the circuit when pushed and keeps it close until it is pressed. As soon as you release the button the circuit is open again. Here, we are going to […]
In this article we’ll learn displaying hello world on LCD; Interfacing 16×2 LCD with Arduino Uno and display some text on it. Writing Hello World pleases the gods of any new programming language that you want to learn. But in case of Arduino it is the LED blinking program that is generally written first. Any […]
LED Blinking on Arduino Uno should be your first Arduino project. Arduino Uno has an on-board or built-in LED, in this project we will see how to blink it. Parts you will need: An Arduino Uno Steps: Connect Arduino with your computer. Download, install and open Arduino IDE. Within IDE chooose File Menu > Examples […]
Arduino is an open-source hardware prototyping platform. It is widely used today in electronics projects because it is easy to learn, simple in design, well documented and cheaper. We call it platform because it is both hardware circuit as well as piece of software, the IDE. It also has its own programming language. All these […]
