Patrick Mccabe’s build this Pong game based on Arduino board and 8×8 LED modules controlled by MAX7219CNG LED matrix driver IC from Maxim. The game is controlled using two potentiometers and is build using professionally made PCB boards. Each LED module has it’s own little control PCB. Check construction details on the link below.

Andrew Schamp has build a temperature datalogger to measure the temperature in his garden. He used a TC74 temperature sensor, 24AA1025 1024kbit EEPROM and a DS3231M+ real-time clock to record the time and temperature hourly onto the EEPROM. He also implemented a serial interface for reading the data at the end of the sampling period. The device is based on Arduino-compatible Boarduino. Every hour, the device takes a sample, and then goes to an extended sleep state, to be awoken an hour later by the interrupt from the RTC. [via]

This project is an automated Android controlled cat feeder based Arduino board. The attached HTC Magic is running SL4A and provides scheduled and on demand feeding as well as an MJPEG webcam feed. The Arduino is hooked up to a SparkFun BlueSMiRF and a simple relay circuit to control the motor. The brackets and food chute were designed in SketchUp and printed on MakerBot. Check it out on the links below. [via]

This project is a garage status monitor that is able to tell when the garage door is open or closed and also monitor the ambient temperature. It is based on an Arduino board, a XBee module and a LM36 sensor. The garage door status is sensed by a roller contact switch, data is handled by a Windows Service and displayed over the web. [via]

This project is a speed detector based on Arduino platform. Arduino is measuring the time it takes an object to travel between two points and transmit this data to a computer or smart phone where it is converted to speed value and presented in a clear way. Check more details on code on the site below. [via]

This project is a Real time clock shield for Arduino based on DS1307 realtime (RTC) integrated circuit. It is a fairly accurate clock that can keep time when not powered if you add a 3V battery. Data is transfered to microcontroller through I²C bidirectional interface. It is connected to Arduino at pins 4 and 5. Check schematic on the link below.
