ESP32 in Blink program v Arduino Web editor-ju
Za prve korake programiranja ESP krmilnikov je mogoče uporabiti kar spletni Arduino Web Editor – spletno verzijo Arduino IDE. Tako se namreč izognemo ročnemu dodajanju gonilnikov za ESP32 krmilnik. Tam je namreč že vse pripravljeno in posodobljeno.
Za krmilnik izberemo: MH ET LIVE ESP32DevKIT
Primer: Priklop treh LED diod na 30 pinski ESP32
Osnove dela z Arduino Web Editor okoljem.

Uporabljen material:
- ESP32 30 pin
- 3x 220 ohm upor
- povezovalne vezice
- mikro USB kabel (za napajanje in programiranje)
