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...

Hello Today i've re build my old project. Here is the schematic : You can use any type of ir receiver with your arduino, i've use an old ir receiver form my brooked tv. after Wiring up all upload this code into your Arduino: /* 5 Channel ir remote control Created by Asghar Furqan A fully open-sourse program! --------------------------------------------------------- circuit: ir module connected to pin 2(Digital) led 1-2-3-4-5 connected to pin 3-4-5-6-7 */ #include int RECV_PIN = 2; int led1 = 7; int led2 = 3; int led3 = 4; int led4 = 5; int led5 = 6; IRrecv irrecv(RECV_PIN); decode_results results; void setup() { Serial.begin(9600); irrecv.enableIRIn(); // Start the ir receiver pinMode(led1,...

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...

yesterday i've bought the Arduino Uno at an local electronic store.and now i want make some simple projects with him. if you want to create some easy projects follow my blog . here i link some easy projects : Blink an led : We have added a 1K resistor to pin 13, what allows the immediate connection of a LED between the pin and the ground. LEDs have polarity, which means they will only light up if you orient the legs properly. The long leg is typically positive, and shoud connect to pin 13. The short leg connects to GND; the buld of the LED will also typically have a flat edge on the side. If the LED doesn't light up, trying reversing the legs. After wiring up you will upload this code from Arduino enviroment to your Arduino Bord. /*...

I’m happy to announce that the Arduino family is now bigger: Priya Kuber (twitter,site) is going to help us out on our blogging queue as well as managing several internal projects. She is living in New Dehli, and has fallen in love for electronics & tinkering at the age of 12 in her fathers’ workshop at home. She is also the co-founder of9circuits, one of our indian distributor.Young, yet well experienced, she is familiar with coding and in dealing with online communities.Above all, I am challenged to share the Arduino Blog with a woman (in a man-oriented world like electronics is) from India (one of the most relevant coutries in terms of electronics and components supply).Stay tuned for new, upcoming surprises!...

[Steve Hoefer] shared an interesting solution for visually impaired people.It measures the distance to things and translates that into pressure on the wrist.[...] It’s wrist mounted and senses objects from about 1 inch (2 cm) to 10 feet (3.5m). It has generally fast response time (fractions of a second) to quickly navigate complex environments.It’s not the first time we see Arduino used for custom solutions to navigate a room and / or enviroment, replacing the sight (above all, you’ll remember the [Bat Googles] project from USI and [Halo], the winner project of Humana competition). “Tacit”, that’s how’s called this cool project, is the first in moving the sensitive response area of the device from the head (closed to the ears) to wrists (closed...
