Build yourself a wirelessly controlled, Arduino-powered message board!

Here’s an easy project which creates a wirelessly programmable message board. It uses XBee modules to provide a wireless serial link between your computer and the device. You interact with it via a simple menu system. There are no buttons (other than the reset button, which is hidden) on the device.

Wise time with Arduino: First release of the Wise Clock 3 software: [via]

The routine work of porting the “Wise Clock 2″ code to the new “platform” (namely the new 3216 bicolor display) went well. Most of features worked right off the bat. Some coordinates had to be adjusted in order to center the text (time etc) on the larger display. These adjustments could have been avoided if the original code used calculations starting from X_MAX and Y_MAX. Ideally, just by changing these two values, the code should have worked.

Asteroids running on Hackvision. Written completely with Arduino:

I implemented Asteroids for Hackvision, written completely using Arduino technology. The ATmega328 is more than powerful enough for real arcade action!

Embedded Newbie has compiled a list of Arduino DAC solutions. [via]

I was in a need of an analog output output for my Arduino, and I found quite many different digital-to-analog converter (DAC) solutions by googling around. So finally I decided to gather them on one page as a reminder for myself and a guide for others. So here it comes!

The Makers Workbench shares this project which measures the rate of liquid flow using a Seeedstudio Water Flow Sensor and Seeeduino.

The flow sensor uses a simple rotating wheel that pulses a hall effect sensor. By reading these pulses the Arduino mathematically calculates the liquid flow with a 3% accuracy rate and sends the reading via serial to the PC. Schematic and Arduino source code included.

This is a simple breath analyzer based on a gas sensor (MQ-3 from Sparkfun) that is highly sensitive to alcohol. The author demonstrates how to interface the gas sensor to Arduino to sense the content of alcohol in your breath. [via]

If you are looking a wireless communication between two Arduino modules, this project might be helpful. It uses low costs RF transmitter and receiver from Sparkfun to establish a radio link between the Arduino boards up to 500 ft. Data can be transferred serially at the maximum rate of 2400 bps. [via]

Here an interesting project showing how to interface a common laptop touchpad with an Arduino. Sample code is included. In the video they demonstrate using the touchpad to control LED patterns through a MAX7219 Led Controller [via]

Pat Arneson built this network monitor that uses a BlinkM, an Arduino, and a little python: [via]

I never appreciated my internet connection enough when I lived in the city. Now that I’m a country mouse I think it really IS a series of tubes. Reliable it’s not. So I thought it would be fun to use an Arduino, my BlinkM and a bit of python to create a visual network monitor.

This is an Arduino powered 24-hour digital clock that uses the RTC chip DS1307 for timekeeping. DS1307 has a small battery backup so that it keeps the correct time even the rest of the circuit is not powered. The time is displayed on 5×7 LED dot matrix. [via]
