Update: Arduino code is pushed with a major bug fix. The original code implimenting the IMU overlapped two button pins. So I burned out an IMU. Worked fine until I turned it off and on again. 🙃 So swapped the two button switch's from pins 22 and 23 of the thing plus to 26 and 25 respectively. IMU and buttons working good now.
Earlier last week I had the time to code the bit for pushing the imu data into node-red! The gif above is the result, where the recursion wings are controlled with acceleration in the x direction.
Skinny is pushing accel and gyro every 41ms over mqtt to Node-red. I'll have the arduino code pushed later after work today.
