Zum Inhalt springen. The following components are required for this project; 1. What you see of the code is what I have. The regular Arduino sketch helps but esp32 does it differently. Berikut saya akan berikan tutorial ESP32 untuk dapat mengakses EEPROM dengan Arduino IDE, dengan LCD oled 0.96 sebagai indikator tampilan datanya. … To send and receive files using the example Arduino sketches below, you'll need a terminal program such as TeraTerm. The ESP8266 family doesn't have genuine EEPROM memory so it is normally emulated by using a section of flash memory. Thanks T – riker1 Jun 21 '19 at 13:44. add a comment | 5 Answers Active Oldest Votes. ESP32 Arduino Projekte. Correct me if I am wrong, please.
