With most of the parts connected and no breadboard used I’m running out of +5V and ground pins. You can probably see my poorly and improperly stacked connectors.
Setup using 2 x IN-14 nixie tubes and Arduino UNO R3

What I really wanted in a sensor was temperature, humidity and barometric pressure (while I’m wishing- with an I2C interface) but after my brief searching I gave up. From what I remember of meteorology a change in pressure often means a change in weather so I’m hoping it’s more important than humidity for what I’d like to do.
Here I'm using an Adafruit BMP085 temperature and barometric pressure sensor.
Again you can see the third digit “5” in a partial transition from another digit.

Believer drum cover is played using midi file, Arduino SD card shield is used to read midi files from SD card.
An Arduino being used to measure the speed of a 12V computer fan. An IR light emitter and photodetector are placed on either side of the fan. As the fan blades spin, they break the beam of light coming from the IR emitter from being seen by the detector. By counting how often this happens, we can figure out how fast the fan is spinning. In this picture, the LCD display says the fan is spinning at approximately 5040 RPM. This was programmed in C++.
This project was interesting because it is a very direct way to see how fast computers really are. The fan is spinning so fast that it just looks like a blur to the human eye, but even this tiny, not-so-powerful microcontroller had no problem keeping up with it and counting the rotations. Very cool.
Massimo Banzi makes the official announcement of the Arduino Uno at the 2010 World Maker Faire in New York City.
This picture was taken with an RevueFlex 3003 and an Auto Revuenon 35 2.8 which was mounted with spacers to achieve this image scale.
Aperture 11; 1/8s; with tripod
It took a while to shoot the images. I was always aware that the exposures were limited and so I tried to give my best.
It is one picture of my first session were I seriously tries to take excellent pictures on film. The film was an "AGFA Photo vista 200" with 12 images.
The development and the scan were made by a big company. In the (digital) post process I only adjust the extract.

4x4 Keypad connected via resistor ladder to single analogue input on Arduino. Currently at breadboard stage. It will be used to control the camera shutter and off camera flash for water drop photos. Circuit using 1 analog input
Just a static display for now for layout.

This is a full shot of the robot while lying down.
This project uses an Arduino to drive a miniature "segway" balancing robot.
A pair of Lego Mindstorm NXT motors are used to drive the robot wheels. An Arduino is used to control the motors. An ADXL335 3-axis accelerometer is used to determine robot orientation. An L293D H-Bridge is used to allow the Arduino to interface with the Lego NXT motors using pulse-width modulation signals. A proportional-integral-derivative (PID) algorithm was used to determine the logic for wheel movement. Programmed in C++.
Unfortunately, the robot required "human assistance" to stand up on its own for any length of time. I wish I had a bit more time on this project to continue tweaking the PID algorithm to improve this.
A thermistor is used to find the temperature of the room. The arduino then updates the speed of a 12V computer fan by use of pulse-width modulation (PWM). As themistor detects more heat, the fan increases in speed, and as the themistor cools down, the fan slows down. An opto-isolator was used to isolate the 12V parts from the Arduino (which operates at lower voltages). The Arduino was programmed in C++.
Of course, this is the first thing one must try.
The Arduino (programmable microcontroller) uses a C-like syntax in a "user-friendly" IDE; you can flash the code to the device via USB, which will promptly reboot and begin running your program.
This example code was provided in a tutorial, and was trivial to get running; what I have planned should be a bit more involved, and interesting.
The Arduino receives a message over serial and coverts it to morse code output on an LED connected to digital pin 13. The Arduino also simulates decoding the message back to plaintext using the LCD display. Programmed in C++.
