The Adafruit AHRS library (Github) and AHRS Learning Guide have been updated with new examples and sections on magnetometer calibration, as well as an example of sensor fusion using all of the available sensor outputs (accelerometer, calibrated magnetometer and gyroscope data). We’re still working on improving this, but if you’re using our 9DOF, 10DOF or LSM9DSO breakouts, you’ll want to have a look at these updates which will help convert the raw sensor data into more useful real world values!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
