Most ESP32 tutorials start at step four. They assume the toolchain is installed, the board already enumerates, and "just add your credentials" is a complete instruction. This series does not.
Each chapter ends with something that works and can be checked. If a chapter's last step does not do what it says, stop there — the next one will not fix it.
Chapters
- Install the toolchainPlaceholder
Arduino IDE or PlatformIO, the ESP32 board package, and the USB driver your laptop is probably missing.
- Flash the boardPlaceholder
Get Blink onto the board, and learn what to do when the upload fails — which the first time, it usually does.
- Connect to Wi-FiPlaceholder
Join a network, survive a reboot, and stop hard-coding your password into a file you will later push to GitHub.
- Read a sensorPlaceholder
Wire a DHT22, read it reliably, and send the numbers somewhere you can see them.
