If you’re like me, after I got my Arduino and performed a final programming on my first chip, I wanted to pull it off my Arduino Duemilanove and put it on my own circuit. This would also free up my Arduino for future projects.

The problem was that I’m such an electronics newbie that I didn’t know where to start. After reading through many web pages and forums, I was able to put together this Instructable. I wanted to have the information I learned all in one place, and easy to follow.

Standalone Arduino / ATMega chip on breadboard - [Link]

Here is how it works. I have an Arduino Duemilanove with ATMega328 which has two photo-resistors connected (with a 10k pull down resistor). I set up two laser pointers to shine a laser directly onto the photo-resistor (which is enclosed within a dark box). The Arduino monitors the values returned from the light sensor, and watches for any changes that indicate that the laser bean has been broken. When both laser beams are broken, the Arduino calculates the amount of time between when each sensor was tripped. It then sends that value to the Adobe AIR based client, which is connected to the Arduino via USB / Serial port and a serial port proxy (in the case, TinkerProxy).

Shield to control 6 relay, 6 digital input and 6 analog input with Arduino Duemilanove, Arduino UNO or Seeeduino. The digital inputs and relay outputs are equipped with an LED that indicates the status. The lines of I/O are connected to the Arduino through corresponding pin-strip pitch 2.54 mm. It gets its power directly from the Arduino module, which provides the 5 volt regulator derived from their contacts between the 5V and GND. The mini-relay Shield of work at 12 volts, so that the relays are working properly will have to connect the Arduino module with an external power supply can provide this voltage. The card can be used in many applications and in many ways. Find in this page a little sketch as to manage I/O via serial commands.

Fabio Varesano has designed what is probably the smallest Arduino compatible board. He writes: [via]

By using the QFN32 version of the ATMEGA 328p, 0.05″ connectors, 0402 components and removing everything not strictly necessary, I’ve been able to design and hand build an Arduino compatible board which is very small (20.7×15.2 mm) and ultra light (2g) but has exactly the same computing power of the Arduino Duemilanove or UNO.

Within this article we are going to examine another new kit available from Freetronics, a company formed to provide many interesting Arduino-based products after the publication of the book “Practical Arduino” by Jonathan Oxer and Hugh Blemings – which in itself is a good read, there are many interesting projects to make and learn from.

Today we examine their answer to “is there a kit version of the TwentyTen Arduino Duemilanove-compatible board?” – by assembling their KitTen. Some people may be wondering why one would want to build a KitTen instead of an assembled unit. Personally I could think of the following reasons:

This project shows how to implement an Electronic Speed Control (ESC) for controlling brushless DC motors. The design is based on an Arduino Duemilanove. To make a Brushless DC motors to work you have to use a motor controller to produce a three phase DC square wave. The test circuit uses 6 2N2222 transistors and six LEDs to help you notice which transistor is switched. Check details on the link below. [via]

This project uses the features of Arduino to make a motorbike computer. It uses an Arduino Duemilanove, Adafruit GPS logger shield kit, USGlobalSat GPS Module, Standard LCD 20×4, Breadboard Power Supply, Polycarbonate Electronics Enclosure to build it. The unit shows GPS coordinates, direction, temperature etc. Check details on the link below.

This project describes how to build a portable solar charger tracker. It analyses the charging process. This unit connects with a small solar panel and a LiPo battery and keep track of solar panel voltage, battery voltage and current goes through the panel to battery charger. The design is intended for 6V panels and single cell LiPo batteries but can be adapted for any kind of panel and charger. Device is powered from batteries and uses Arduino Duemilanove. [via]

The latest Arduino in the family is the Arduino Duemilanove (which means “2009”) and includes 14 digital input/output pins of which 6 can be used as PWM outputs, 6 analog inputs, a 16 MHz crystal, USB connection, power jack, an ICSP header, and a reset button. The main difference between this and the last version, the “Diecimila” is that this version automatically selects the power source for the boards, dispensing of the old USB/External power jumpers and it also adds a way of disabling the auto-reset of the board, but includes a solder jumper just in case you need to re-enable it.
