Lifeboat Farm » The finished Arduino wireless water sensor Back at the end of 2009 I started playing about with an Arduino solution to monitor the water level in a water tank about 300m from the house. The tank isn’t visible from the house so a standard visual tank indicator wouldn’t work. In a nutshell, this sensor measures resistance through an array submerged in the tank to determine the water level, then sends that data back to a server in the house for humans to read. There were a few more steps beyond the prototype required to make it really useful and along the way I discovered some issues with the first model which I’ve improved on, but that’s why you call it a prototype. Here is the Arduino with an added WiFly shield – an add-on that gives the Arduino the ability to (mostly) seamlessly communicate over the farm’s existing 802.11 WiFi network. And here’s the whole assembly in the waterproof (IP66) project box. The close up shows it’s a pretty snug fit in there. The enclosure mounted on a post just above the water tank. The Code:
News Paparazzi Main Page Arduino Passion: projects, news, tutorials, all Arduino resources you ever need. Colorduino | Nick's LED Projects Beta Board Preview Colorduino running the Plasma demo. The Colorduino takes a lot of the difficulty out of of controlling an RGB LED matrix, something I was stumped with as a beginner in electronics. It’s built around the ATmega328 CPU, the heart of the Arduino platform, and builds on previous matrix controllers like the Rainbowduino from Seeed Studio. iTead have made sure the Colorduino is pin compatible with the Rainbowduino so it can slot in with existing projects, but have upped the specifications to get better performance. The Colorduino board One of the Colorduino’s main features is that it uses a DM163 LED driver chip to provide hardware PWM. The DM163 chip also provides 3 x 6bit correction registers, useful for calibrating the respective brightness of each color channel in software. Colorduino (left) and Rainbowduino Colorduino and LED matrix from Cool Components Power to the board is either via pin headers or 2 sets of mini screw terminals.

Monitor program for Arduino in Japanese [ArduinoConf][ArduinoMonitor][iArduino] Abstract You can control Arduino's pins by ArdunoMonitor and watch changes on pins. Before you begin Place iArduino folder into your libaries folder of your Arduino folder. Start ArduinoMonitor Connect Arduino and PC, then execute ArduinoMonitor. The connection is terminated by clicking ``Disconnect'' button. Changing pin modes and values Select the usage of the pins from pull down menu on the side of the pin. Converting analog value If you check ``show in voltage'', the values of analog pins are show in voltage rather than direct value. Logging It starts logging in CSV format by clicking ``Start Log'' button. Displaying a graph It shows a graph window by clicking ``Graph'' button. It stops updates of the graph by clickng ``Stop'' button. Saving and loading a configuration It saves and loads configuration in XML format by clicking ``Save'' and ``Load'' buttons. Example sketch Pressing `Show code' button shows source code for Arduino IDE. Notes
My QuaXCopter Project. Hi Everyone. I've been working on my Quadrotor project for one year. My last attempt was not good enough to fly. The control board worked well, but... i had problem with the frame. The frame was not enough rigid to absorb the mechanical vibrations coming from the motors. Some months later, I decided to give the project another try, with new changes on the control board and definitely on the frame "the frame will be smaller". Stellaris Cortex-M3 microcontroller (LM3S5749).IMU sensor 9DOF sensor stick.Wireless communication via Bluetooth or RF, (Bluetooth module UART and NRF24L01 module SPI).Temperature Sensor.Sonar Sensor.USB connection. I would like to show you some pics of the control board: The rest of this month and the next one, I will work it on the firmware development. Would accept any suggestion or recommendations. Regards.

Arduino Tutorial - Learn electronics and microcontrollers using Arduino! So, I get two or three emails a day, all basically asking the same thing: "Where can I learn about electronics?" In general, most of these people have seen some of my projects and want to be able to build similar things. Unfortunately, I have never been able to point them to a good site that really takes the reader through a solid introduction to microcontrollers and basic electronics. I designed this tutorial course to accompany the Arduino starter pack sold at the Adafruit webshop. Follow these lessons for happiness and prosperity. Lesson 0 Pre-flight check...Is your Arduino and computer ready? Here are some recommended tools: If you need to get any soldering done, you may also want.... All of the content in the Arduino Tutorial is CC 2.5 Share-Alike Attrib. Love it? To some extent, the structure of the material borrows from: The impressively good "What's a microcontroller?"

View topic - Website controlled Arduino Ethernet • Jaycon Systems Forum Description:There are many pages online offering to show you how to host a website from an Arduino Ethernet, and control the Arduino from that hosted website, but those mainly share the same method: sending a request by changing the website url address.In this tutorial, I will be using the second available HTML method: sending a request by actually sending a DATA packet. Video Hardware:Arduino Ethernet: Shield V2: ResultHere's a screenshot of what I get with the code in this tutorial.Hosted by an Arduino! Advantages or this method- You can send any data type (including files), and are not limited to ASCII- You can send any data length and are not limited by the url size- Your data is Hidden, can be encrypted, and is difficult to hack (has to be used for applications using passwords) Code: Select all #include <SPI.h>#include "Ethernet.h" Code detailed Ethernet configuration
