Arduino pH Meter with USB Interface

LeoPhi is arduino-based pH sensor with USB interface. It can be used as standalone sensor or be part of another embedded system. The project settled on the USB enabled Atmega32u4, which is a fully USB compatible, with 2.5k of RAM and 32K of flash. It is also the chosen MCU for the Arduino Leonardo and allows users a lot of flexibility in adding pH reading and control to any project. Since the release of the Leonardo and Arduino1.0.1 it is very easy to use and program this unit to match whatever a project demands.

Open Source Arduino CAN-BUS OBD Gas Gauge

If you want to add OBD Gas Gauge instrument to your old car, you can try to build your self CAN-BUS OBD Gas Gauge based on Arduino like winneymj did. Before build this project, make sure that your car supports CAN-BUS protocol. Not all cars do, especially older cars, before 1998, but more and more new cars do.
