Accelerometer sensor

Detect acceleration changes on a freely moving mouse using lightweight, readily available electronics.

Note there are two versions of the accelerometer assembly; one with an analog sensor and one with a digital sensor.

Components for the analog sensor

Components for the digital sensor

Assembly instructions for the analog sensor

  • With the help of a utility knife, cut 6 flex cables.
  • Connect pins labeled Z, Y, X, GND, VCC to pins A2, A1, A0, GND, and 3.3V of the microcontroller.
  • Connect the center pin of a BNC interface to any of the three axis (A2, A1, A0) and the side pin to GND of the microcontroller.
  • Install Arduino IDE.
  • Upload the code after selecting Arduino UNO as the board.

Assembly instructions for the digital sensor

  • With the help of a utility knife, cut the flex cable to keep only 6 lines and remove the blue plastic from both ends to expose the metallic wires.
  • Connect pins labeled SCLK, MOSI, MISO, CS, GND, and V+ of the accelerometer board to pins 15, 16, 14, 10, GND, and VCC of the microcontroller by soldering corresponding wires of the flex cable.
  • Solder the BNC black and red cables to GND and pin 9 of the microcontroller (respectively).
  • Melt a small amount of glue stick or add 2-part epoxy to protect the cables from breaking. Repeat for the microcontroller.
  • Place heat shrink around the sensor and the microcontroller.
  • Install Arduino IDE and the Arduino Addon for SparkFun boards.
  • Install the ADXL362 library using Arduino IDE's library manager.
  • Upload the code after selecting SparkFun Pro Micro as the board and Atmega32U4 (3.3V, 8MHz) as the processor. To avoid permanently damaging the microcontroller, do not attempt to upload the code using any other combination of board and processor from the IDE.

Usage

  • Configure your data acquisition system to read analog data from one of the input ports.
  • Connect the BNC cable to the analog port of the data acquisition system.
  • Power the microcontroller with a usb cable.
  • If using the analog sensor, you may change the sensitivity by sending a 0 over the serial port while the sensor sits still.
  • Attach the accelerometer sensor to the subject.
  • Use the serial port to read the processed 3-axis signal or the the BNC port to read the values from a single axis (raw values for the analog sensor; processed values from the digital sensor).

Version History

0.1.0

  • 2023-09-29
    • Added components, assembly instructions and code for the analog version of the accelerometer sensor.
    • Added a sensitivity calibration mechanism for the analog sensor.
