3 and Zero W

and warm white Adafruit LED Sequins

one for the Raspberry Pi and one for the Servo Pi please ensure that the ground wires on the two supplies are joined and do not have any potential difference between them

We strongly suggest reading the excellent tutorial document written by the makers which discusses use

Fermion: LSM303 Tilt Compensated Compass (Breakout) _RPI_CASE_AUDIO 3 and Zero WThe LSM303DLH is a triple axis accelerometer combined with a triple axis magnetic sensor. This breakout board uses the LSM303DLH to give you the data you need to feed into a microcontroller and calculate tilt compensated output. Applications Compensated compassing Map rotation Position detection Motion activated functions Free fall detection Intelligent power saving for handheld devices Display orientation Gaming and virtual reality input devices
