Set things up
Let us guide you through the ESP32 world
ESP32 planars come dime a dozen. We will use the DEVKIT C, which is conveniently available from https://www. elektor.com/esp32-devkitc. First, make sure that all relevant drivers are installed and that the serial port becomes visible. As we work on Linux, we expect it to mount at /dev/ttyusb0. Open a recent Arduino IDE (>=1.8), and use the board manager to install an ESP32 core according to the steps outlined at https://github.com/ espressif/arduino-esp32/blob/ master/docs/arduino-ide/ boards_manager.md. Next, open the Board choice tool and select “ESP32 Dev Module”. Finally, use the Tools menu to select the correct serial port. When setup is complete, deploy a sketch of choice – if the programming process succeeds, all is well.
