Technical requirements
We will use Visual Studio Code and ESP-IDF command-line tools to create, develop, flash, and monitor the applications during this chapter.
For hardware, only ESP32-S3 Box Lite will be employed. The sensors and other hardware components of this chapter are:
- A light-dependent resistor (LDR)
- A jumper wire (both ends are male)
- A pull-up resistor (10K)
The source code in the examples is located in the repository found at this link: https://github.com/PacktPublishing/Developing-IoT-Projects-with-ESP32-2nd-edition/tree/main/ch4
