In the above circuit diagram,GPIO22is connected with an anode pin of LED, and another pin of LED is connected with ground through a 330ohm resistor. you can check theLED blinking tutorialfor more information about it. Next push button one terminal is connected with 3.3 volts of ESP32 and ...
BOOT按钮:此按钮可用作输入,或将板置于ROM 引导加载程序模式。它在 CircuitPython 中可用board.BUTTON,在 Arduino 中可用0。要进入 ROM 引导加载程序模式,请按住 BOOT按钮,同时按一下上述RST按钮。 一、开发前的准备工作 1、下载ArduinoIDE 官方网站:https://www.arduino.cc/en/software ...
