This sketch makes the Arduino work as a GPIO interface for a computer, where input and output changes are transmitted in run-length encoding. Every time an input pin changes, the Arduino sends the new values of the input pins and the time since the last change. In a similar way, the Arduino can be programmed a sequence of output pin changes, each specified by the new values of the output pins and the time since the previous change. Three application programs are included: the first makes two digital pins act as a TTL-levels UART; the seconds turns the value of the input pins into an image; the third reads codes from infrared remotes with a photodiode and a resistor connected to one of the input pins.

PK2Aux is a library and suite of command-line utilities for using the Microchip PICkit2 programmer device for purposes other than programming (such as the generic pin controls, serial UART, and logic analyzer modes provided by the Windows software).

... * Soil Moisure Sensors are responsible for sensing if the soil of irrigated flowers are wet or not. These sensors are attached to the Sensor Controller Module via slow speed I2C bus. The modules use 2-pin probes and drives them with 4 kHz square wave in order to avoid oxidating the probes. In my implementation I used these small water pumps from Conrad: http://www.conrad.hu/conrad.php?name=Products&pid=539090 The whole system is powered by a 12V / 4A SMPS.

...The code is compiled for the ATmega328p so the supported boards should be: - Arduino Uno - Arduino Duemilanove - Arduino Diecimila - Arduino NG - Arduino Extreme v2 - Arduino Extreme Note: only tested on Arduino Duemilanove No schematics are available yet, but please have a look at the MegasquirtAVR schematics. It is meant for the ATmega128 so not pin compatible.

This is a RGB LED Pin-back Button controlled by an AVR Microcontroller.

The system uses internal databases to store led information such as pin number, target brightness, time at which the brightness should be reached and current program number. When the target is reached the led looks for the next program and get new time and brightness. Leds and programs can be manipulated on the fly, in the program or from serialusb. A very simple task scheduler call the update of leds every 5ms, leaving plenty of processor for other tasks.

A lightweight, simple and easy to use embedded system task scheduler. RataOS is written as a high level C, with a simple HAL & API structure, allowing it to be ported between embedded devices easily.
