How to use ESP32 as a webserver

£10 ESP32 is a 240mhz dual-CPU computer (with 4mb ram) and can run a webserver - so can be controlled from your phone/computer. Amazing. These are the steps I took to get it working:

• download current arduino IDE from arduino.cc
• the one I bought from the Hackspace shop was this one:
• CANADUINO ESP32 Devkit Wi-Fi Bluetooth BLE - Ultra Low
• https://www.amazon.co.uk/CANADUINO-ESP32-Devkit-Wi-Fi-Bluetooth/dp/B07F1GWJ1N
• the IC chip (which controls the USB interface with the computer?) is: CP2104
• my mac, is running an older system, so I needed this driver for the CP2104:
• https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers
• after that, in the arduino IDE, you need to add a URL to the preferences in order to download the ESP32 board:
• https://www.youtube.com/watch?v=mBaS3YnqDaU
• this is the URL to type: "https://dl.espressif.com/dl/package_esp32_index.json"
• Then this video + link give you code to make the webserver:
