Are you getting wonky readings from the magnetometer on your IMU? Do the compass headings make no sense at all? Your magnetometer may have become magnetized to the point that all the readings are distorted by its own magnetic field. This can happen if your magnetometer is exposed to a strong magnetic field, like getting too close to a magnet or an electric motor.
The good news is that you can fix this with an inexpensive magnetizer/demagnetizer tool available for just a few dollars at your local hardware store or home improvement center. Just wave the sensor back and forth over the stepped part of the “demagnetize” side of the tool to neutralize the magnetic field.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
