My Favorite Projects with Arduino UNO and Mega2560

Updated on October 21, 2017

Introduction

Below I list a series of my favorite projects in which I use the Arduino UNO and Mega 2560 boards in combination. The interesting thing about these works is that they can serve us to be able to realize others of greater complexity.

01 RF COMMUNICATIONS WITH ARDUINO UNO AND MEGA 2560

In this project we will perform three exercises and using the VirtualWire library. The communication will be via RF at 433 MHz, the transmitter will be the Mega 2560 board and the receiver the Arduino UNO board.

Exercise 1

When you sent the "y" character, an LED is lit. And when I send the "z" character, the LED turns off.

Exercise 2

Here the sending circuit sends the message "HELLO WORLD" and the receiver receives them, we can see the message on the serial monitor.

Exercise 3

In this exercise we send two data and each with a different frame start for each data and in the receiver we can see which data is the one being sent.

02 SERIAL COMMUNICATIONS WITH ARDUINO UNO AND MEGA 2560

The Arduino UNO board will serve as a transmitter and the Mega 2560 receiver, we organize the data frame with a start byte, data and data validation. In short, we are going to send a count of data from 1 to 255 to restart again and these we can see them in the serial monitor.
