Heare is a Speed meater by BAXX an Arduino user. source: http://www.smartphone-time.com/2011/09/09/arduino-samp-speedmeter/ SAMP sends vehicle speed to a php script which a program on pc reads and echoes that data to COM port, so you can plug in this speed meter to a remote pc and monitor if your friend is speeding in samp. <-- This is computer softwere. ...

Fading Demonstrates the use of the analogWrite() function in fading an LED off and on. AnalogWrite uses pulse width modulation (PWM), turning a digital pin on and off very quickly, to create a fading effect. The Circuit Connect the anode (the longer, positive leg) of your LED to digital output pin 9 on your Arduino through a 220-ohm resistor. Connect the cathode (the shorter, negative leg) directly to ground. /*  Fade  This example shows how to fade an LED on pin 9  using the analogWrite() function.  This example code is in the public domain.  */ int brightness = 0;    // how bright the LED is int fadeAmount = 5;    // how many points to...

LiquidCrystal - autoscroll The Liquid Crystal Library allows you to control LCD displays that are compatible with the Hitachi HD44780 driver. There are many of them out there, and you can usually tell them by the 16-pin interface. This example sketch shows how to use the autoscroll() and noAutoscroll() methods to move all the text on the display left or right. autoscroll() moves all the text one space to the left each time a letter is added noAutoscroll() turns scrolling off This sketch prints the characters 0 to 9 with autoscroll off, then moves the cursor to the bottom right, turns autoscroll on, and prints them again. Hardware RequiredArduino Board LCD Screen (compatible with Hitachi HD44780 driver) 10k Potentiometer breadboard hook-up...

The Arduino Kitchen Timer is a simple timer based around a 10 bar LED Bar Graph, with a Piezo-Electric Buzzer. A line of 10 LED's could also be used, and each LED represents a segment of 5 mins. Once the Arduino is reset the user holds a pushbutton and the Bar Graph counts up in chunks of 5 mins, until the user lets go of the button. The timer then times 5 mins, and the last LED is turned off, etc until the timer is finished. The LED bar graph then shows a display, and a piezo buzzer sounds an alarm. The project is made by Ari Cooper Davis Make it: you will need: An Arduino Jumper Wires A momentary push button A 10 Bar LED Bar Graph or 10 Normal red Leds A Piezoelectric Buzzer A 10k resistor Now build the circuit And...

Parts Breadboard Atmega644 16MHz crystal momentary switch 4 x .1uF capacitor 2 x 22pF capacitor 10K resistor And some wire. Put the bread board down vertically. Row 1 at top, blue rail left, red rail right. Place the 644p into the bread board. Pin 1 into bread board hole 10D. Place the momentary switch's pins into bread board 1D, 1F, 3D, and 3F. Place the crystal into rows 31E and 33E Place a .1 uF cap from 9E to 9F. This is the reset on RTS cap. We'll be "building" a serial port on the left side, rows 4-9. Place a .1 uF cap from 18I to 19I. Decouple AREF from AGND. Place a .1 uF cap from 19I to 20I. Decouple AVCC from AGND. Yep, 19I, has 2 cap leads in it. It's a tight fit but can be done. Place a .1 uF cap from...

For Building an Sanguino you will need the Sanguino kit, you can bay it here : Sanguino Kit Mounting Instructions : This is the Sanguino PCB These Are The Components : Solder Pin Headers The pin headers are supposed to point down so you can insert the Sanguino into a breadboard. Make sure they are soldered in straight (perpendicular to the board.) An easy way to do this is to solder in one pin on each end of the row so that you can easily adjust them. Once they are straight, solder the rest of the pins. 10K resistorSolder the resistor in any orientation. It is marked brown / black / orange. 22pF capacitorsThese are the tiny yellow capacitors. They can be soldered in any orientation. Serial HeadersSolder in the...

Sanguino is an open source hardware like Arduino( infect it use the Arduino Ide)but it has some additional I/O pins for example it has 32 total general purpose I/O pins, 64K flash memory, 2K EEPROM etc.. the Main Processor is atmega644P and obviously its 100% open source. ...

A beautiful project by [Leigh Davis]. It is a brilliant proof of how Arduino fits into virtually any sphere of thought and is the shortest path for a creator realizing his idea in reality.He writes:I began the first few days by developing a stand alone application build in MaxMSP that understands the notes that a play on my (recently purchased second-hand) flute. I set the range from low C right up to the 3rd octave D. Each note of the chromatic scale triggers a bang, which is coloured uniquely to the other notes bang messages.The bang message then sets the corresponding color to the display screen on the application. Which will in turn send a signal to the arduino to dispense the corresponding oil color on water according to the...

Introduction Arduino is a great starting point for electronics, and with a motor shield it can also be a nice tidy platform for robotics and mechatronics. Here is a design for a full-featured motor shield that will be able to power many simple to medium-complexity projects.2 connections for 5V 'hobby' servos connected to the Arduino's high-resolution dedicated timer - no jitter! Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution) Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping. 4 H-Bridges: L293D chipset provides 0.6A per bridge (1.2A peak) with thermal shutdown protection, 4.5V to 36V Pull down resistors keep motors...
