Halleffect sketch of ESP32 Course Q&A Forum › Category: ESP32 › Halleffect sketch of ESP32 Course 0 Vote Up Vote Down Allen Applegarth asked 6 years ago The sketch as written does not work. The Serial.begin value is wrong. It needs to be 115200. 1 Answers 0 Vote Up Vote Down Rui Santos Staff answered 6 years ago Thanks for letting me know. The code works if you open the serial Monitor at the baud rate of 9600… But I’ll update it to 115200 in a future course update. Thanks again, Rui
