pic: Arduino datalogger

[The Doctor]

Here is a datalogger that I have been designing for use in testing our robot.

Parts:



I used two IMUs from past Kits Of Parts, along with a Parrallax 3-axis magnetometer. This ended out with a total of 9 degrees of freedom:

• 3 axis magneto
• 3 axis accelerometer
• 2 axis accelerometer
• A rotational gyro

Not really degrees of freedom, but these are there too:

• A temp. sensor for the gyro
• An RTC
• 4-5 DS18B20 temp sensors (for motors)
• SD card for datalogging

It periodically gets the data from all the sensors, and prints it to the serial port and saves it to a CSV file on the SD card.

I will make the code available soon, once I get an SD card glitch worked out. I really wish we had finished our robot sooner (that 11:58 on the last day), because I wanted to try it out with this datalogger.
