Hi Friends! Hope you are doing great. Today, I am going to give you a detailed Introduction to Arduino Uno . It is a microcontroller board developed by Arduino.cc and is based on Atmega328 Microcontroller . The first Arduino project was started in Interaction Design Institute Ivrea in 2003 by David Cuartielles and Massimo Banzi with the intention of providing a cheap and flexible way for students and professionals to learn embedded programming. Arduino UNO is a very valuable addition in electronics that consists of a USB interface, 14 digital I/O pins(of which 6 Pins are used for PWM), 6 analog pins and an Atmega328 microcontroller. It also supports 3 communication protocols named Serial, I2C and SPI protocol. You should also have a look at this video presentation on Arduino UNO: Few main ...
Hello friends! We have already covered the Introduction to XBee Module and Interfacing of XBee with Computer . In this tutorial, we will connect our configured radios to two Arduino UNO Rev3 boards and use a pushbutton on one board to control the built-in LED on the other. We will build the project in stages. First, we will establish the power and serial connections. Next, we will define the messages sent between the boards. Finally, we will write separate sender and receiver sketches and examine how they handle button bounce, incomplete messages, and a lost wireless connection. The example assumes two compatible radios already configured for transparent serial communication at 9600 baud. The address values carried forward from the previous lesson apply to classic S1 802.15.4 firmware. Rad ...
