This is a library for the Adafruit LIS3DH Accel breakout board
Designed specifically to work with the Adafruit LIS3DH Triple-Axis Accelerometer (+-2g/4g/8g/16g)
Pick one up today in the adafruit shop! ---—> https://www.adafruit.com/product/2809
This sensor communicates over I2C or SPI (our library code supports both) so you can share it with a bunch of other sensors on the same I2C bus. There's an address selection pin so you can have two accelerometers share an I2C bus.
Adafruit invests time and resources providing this open source code, please support Adafruit andopen-source hardware by purchasing products from Adafruit!
