StateChangeDetection Once you've got a pushbutton working, you often want to do some action based on how many times the button is pushed. To do this, you need to know when the button changes state from off to on, and count how many times this change of state happens. This is called state change detection or edge detection. In this tutorial we learn how to check the state change, we send a message to the Serial Monitor with the relevant information and we count four state changes to turn on and off an LED. Hardware Required UltrasonicSensor Better library: NewPing The example below is a simple implementation that is easy to understand and great for simple testing. However, it is slow, is not meant to be run from interrupt code, and does not bound the pulseIn call by adding ", 38000" or whatever the appropriate maximum timeout (in microseconds) is for your sensor. In other words this code can introduce up to a 1 second delay as the worst case timeout to pulseIn. If you need more efficient code that can be run from interrupts and can be used to talk to multiple sensors at the same time, look at NewPing from

Arduino I have finally taken the plunge and released Servo Tools For Maya to the world! Servo Tools For Maya is a Python Plugin that sends rotational values over USB the the Arduino Micro Controller. These values are then converted in to Pulse Width Modulation which is used to control multiple Hobby RC Servo Motors. Applications for the plugin are only limited to your imagination. 15 Arduino Projects that you will love to see Do you know Arduino borrowed its name from a nearby watering hole called Bar di Re Arduino where it was first developed in Italy? See this infographics first, created by Make: magazine. Click here if you want to see it full screen. Opens in a new window. It is 10 years after its appearance and by now we all know the super popularity of Arduino – the first open-source hardware and software combination platform that millions enthusiasts as well as professionals all around the globe uses for making their electronics projects prototypes. It includes microcontrollers that can receive various inputs from different custom devices such as a light or pressure sensor.

How to Upload a Sketch to an Arduino - dummies By John Nussey The content of circuits and Arduino sketches can vary greatly. Before you get started, there is one simple process for uploading a sketch to an Arduino board that you can refer back to. Follow these steps to upload your sketch: Connect your Arduino using the USB cable.The square end of the USB cable connects to your Arduino and the flat end connects to a USB port on your computer.Choose Tools→Board→Arduino Uno to find your board in the Arduino menu.You can also find all boards through this menu, such as the Arduino MEGA 2560 and Arduino Leonardo.Choose the correct serial port for your board.You find a list of all the available serial ports by choosing Tools→Serial Port→ comX or /dev/tty.usbmodemXXXXX. X marks a sequentially or randomly assigned number.

Finding Parts - Hobbyist / Surplus Sites The data on the "Finding Parts" pages is actually all in a Wiki (a webpage that anyone, even you, can edit!) If you have suggestions or ideas for other companies or sources you can post it in the forum but it might be faster and easier to just edit the wiki page yourself! (You'll have to make an account arduino meets processing - PUSHBUTTON The Arduino meets Processing project intends to make it as easy as possible for anyone to explore the world of physical computing. All you need is an Arduino board as well as the Arduino and Processing software, which you can download on their project websites. On this website we explain how to: set up electronic circuits with various kinds of sensors, control and measure the sensors with the Arduino board, send the data to the computer,
