Atmega
This is part of my Arduino Controlled PC Liquid Cooling Information Center I have been working on and I thought I would share it here since there have been a few threads on arduino.cc and seeedstudio.com on how to read water flow rate in liters per hour using the Water Flow Sensor found in the Seeed Studio Depo. It uses a simple rotating wheel that pulses a hall effect sensor. By reading these pulses and implementing a little math, we can read the liquids flow rate accurate to within 3%. The threads are simple G1/2 so finding barbed ends will not be that hard. I found some at Lowes for $1.89 each.
Protostack clues us in on using I/O Registers on AVR Micro Controllers.

Protostack has posted a very nice tutorial on using I/O registers on AVR micro controllers. Just like all of Protostacks tutorials, this one is detailed, easy to understand, and beginner friendly. They include lots of photos, diagrams and sample code to explain everything. While you are there you might consider picking up one of their ATMEGA 128 protoboard kits.
Need a flexable Arduino? Seeed Studio has that!

For a couple of months now we have been reading snippets of information on Seeed Studio's newest Arduino variant. It promised to be the smallest ever and be flexible. How could it be flexible you ask? That’s quite simple. Seeed Studio designed the board on a flexible film similar to ribbon cable found in electronic devices that use it to connect a display to the PCB. Seeed Studio says that it is “cutable, scaleable, and chainable.” They are in the process of creating a few prototypes and if you leave a detailed comment on their blog post, on how you would use it, they might send you one to test with.

Update + Development Setup Pics
Over the last few weeks I have had several emails asking what my development setup looks like for this project. Today I am going post a small update and a few photos of my development setup. First I would like to give a big shout out to all the guys over at Seeed Studio. Their Seeeduino has played a big role in this project and now we will be using their Seeeduino Mega along with 2 of their Water Flow Sensors to complete the project. Stop by their online store and check them out for all of your open source project needs. Keep reading after the jump for more ACLCIC excitement.
Part 2: Reading Fan / Water Pump RPM
In part one I covered how to connect two temperature sensors and the LCD to our Aruino. In this installment I am going to show you how to read the RPM of the water pump. The Arduino Controlled PC Watercooling Information Display will display the water pumps RPM on one screen so I had to figure out how to read the RPM from the data output by a Hall effect sensor...more after the jump...
