Working with Arduino

This chapter includes the following sections:

• Setting Up the Development Environment
• Example

Setting Up the Development Environment

1. Installation and Configuration

• For setting up the Arduino environment and basic usage, please refer to this R4 link; R3 comes pre-installed by default.
• After setting up the environment, connect the sensor and download the example package.

2. Hardware Configuration

• The IO level of the Arduino board must be 3.3 V. If using 5 V IO levels, a level shifter is required; otherwise, the sensor may be damaged.
• When using Waveshare R3/R4, set the following jumpers to 3.3 V.
