irrighino

Irrighino is a complete watering system, based on Arduino Yun. The main features are: [checklist] a configurable number of solenoid valves an AJAX web interface a weekly schedule manual activation / deactivation [/checklist] Here’s a short video that describes the project: How it works An Arduino Yun – the “brain” of irrighino – is connected to the switch panel…

Yún – Toggle a LED via web

In my previous tutorial you learned how a sketch, running on the Arduino Yun’s ATMega chip, can execute processes (commands, scripts…) on Linino thanks to the Bridge library. In this tutorial you’ll learn how to do the opposite: send commands from Linino to the sketch that runs on the microcontroller. YunServer & YunClient In my sketch I’ll use two objects from the Bridge library: [checklist] YunServer,…

Yún – SMS alarm

This tutorial will explain a way to communicate between the sketch running on the ATMega and the Linino (Linux) OS running on the Yun’s SoC: the ability to execute Linux processes from a sketch. I’m going to build a simple SMS alarm: A microswitch is connected to the Arduino when the microswitch is pressed, an SMS is sent using Skebby gateway…

Yún – USB wifi adapter

The Arduino Yun has an embedded wireless network card. Unfortunately, that card doesn’t support an external antenna. If you take a close look at the board, you may notice a connector similar to the U.FL one normally used to connect an antenna: That connector, as someone explained on the official forum, is only used for testing purposes and it’s not…
