Example for Serial Studio and Nano 33 IoT
3+
Reads a joystick on A0, A1, and D2
4+
and the accelerometer and gyro on a Nano 33 IoT
5+
Serial Studio download: https://github.com/Serial-Studio/Serial-Studio/tags
6+
Tutorial: https://www.alex-spataru.com/blog/introducing-serial-studio
7+
Uses the following library:
8+
http://librarymanager/All#Arduino_LSM6DS3
9+
The circuit:
10+
- Joystick H axis attached to pin A0
11+
- Joystick V axis attached to pin A1
12+
- Nano 33 IoT built-in LSM6DS6 IMU
13+
14+
Included in the project folder are 3 JSON files for Serial Studio:
15+
joystick.json, imu.json, combined.json
