5. Setup and Operation
5.1 Initial Setup
- Insert Development Board: Carefully insert the ESP32 development board into its designated socket on the expansion board. Ensure correct orientation.
- Power Connection: Connect the USB cable to the ESP32 board and to your computer. Alternatively, use the battery holder with DC connector to provide power (7-12V).
- Software Installation: Install the Arduino IDE on your computer. For ESP32 programming, you may need to add the ESP32 board manager URL in the Arduino IDE preferences and install the ESP32 boards.
- Driver Installation: Ensure necessary USB-to-serial drivers (e.g., CP210x or CH340) are installed for your operating system to allow communication with the ESP32 board.
5.2 Basic Programming
The kit supports two primary programming environments:
- Scratch: A graphical programming tool suitable for beginners, especially teenagers, to learn programming concepts through drag-and-drop blocks.
- C/C++ (Arduino IDE): The C/C++ language, widely used in embedded systems, is supported through the Arduino IDE. This allows for more advanced programming and direct control over the hardware.
