[HW] Getting started: Speed measurement
To measure speed we will use an Aimar ST650 connected to an Arduino.
The Aimar ST650 has a paddleweel with four asymmetrical, hydrodynamic blades and hall-effect magnetic sensor for high-level pulse output.
Connecting ST650 to an Arduino Board:
- Bare cable to GND.
- Red cable to +5V.
- Green cable to pin A0.
This first basilar sketch will count paddlewheel’s complete rotations:
