Precautions
Two Axis angular displacement sensor is NOT 5 V tolerant. Requires 1.62 - 3.6 V
regulated supply for proper operation.
Don’t pull the sensor by the wires
Don’t strain the sensor more than 15%

Device Setup
1: Connect Two Axis sensor to the included trinket M0 as shown below:
2: Set up Trinket M0 Arduino IDE
oFollow Adafruit’s guide found at https://learn.adafruit.com/adafruit-
trinket-m0-circuitpython-arduino/arduino-ide-setup to get the Trinket M0
up and running in the Arduino IDE.
3: Integrate Sensor and Trinket
oDownload example sketches and ads_two_axis Arduino driver at (github
link)
oCopy two_axis_ads_demo sketch into your Arduino folder
oCopy folder ads_two_axis_driver into Arduino/Libraries folder
oConnect the Trinket M0 to a USB port
oSelect Trinket M0 from the Arduino board manager and the associated
COM port
oFlash two_axis_ads_demo sketch onto trinket M0

Expected Output
1: Click on tools and then Serial Plotter in the Arduino IDE or CTRL+SHIFT+L to
verify that angular data coming from the Two Axis sensor is correct. (Note that touching
the sensor while coupled to AC power can cause 60 Hz line noise).
2: Click on tools and then Serial Monitor in the Arduino IDE or CTRL+SHIFT+M to
interface with the Two Axis Sensor through the serial port. A list of serial commands
can be found in the parse_serial_port function in the two_axis_demo sketch.
