I have a 10 DOF sensor with wire outputs labeled "VIN", "GND", "SCL", and "SDA". I would like to wire these into my arduino and ultimately obtain x, y, and z displacement. This might sound like a simple problem for a veteran but I have gotten lost in the literature and code. Where can I learn how to do this or is there a library that I can use?

  • Google "10 DOF IMU" should give you plenty of information. Here is a learning resource based on Adafruit products learn.adafruit.com/products/1604/guides – hcheung Feb 24 at 0:43

    When asking a question here it is always appreciated if you include part numbers. Or vendor web pages. Guessing, SCL is a serial clock line and SDA is the serial data line. So it sounds like you have a chip which talks over an I2C serial bus. So you need the I2C Arduino library. But, the real problem - what does the chip look like inside? How many registers? What do the bits mean in those registers? How do you control this chip? That's why you need a part number. – st2000 Feb 24 at 0:44
  • Step one: Read the number(s) on the chip(s). Step two: find libraries and tutorials for those chips. – Majenko Feb 24 at 11:37
  • I think this is it. dfrobot.com/product-818.html – Nick Knapp Feb 25 at 16:57
  • The link to the datasheets is at the bottom of this page, wiki.dfrobot.com/10_DOF_Mems_IMU_Sensor_V2.0_SKU__SEN0140, but I don't know what is relevant in my case. – Nick Knapp Feb 25 at 17:13
