ESP32是Espressif Systems推出的一款具有Wi-Fi和蓝牙功能的单片机。 点亮LED的代码(使用Arduino IDE): #define LED_BUILTIN 2 // ESP32的内置LED通常连接到GPIO2 void setup() { pinMode(LED_BUILTIN, OUTPUT); } void loop() { digitalWrite(LED_BUILTIN, HIGH); delay(1000); digitalWrite(LED_BUILTIN,...
I had an issue with ESP32 and TelegramBot of the LED (BuiltIn LED - PIN 2) just flickering and flashing randomly. Wanted to pull my hair out! BUT... What I found, I bought a Wroom off Aliexpress and had it in Arduino as the Wroom (One of the three). When I changed it to ES...

它在 CircuitPython 中为board.LED,在 Arduino 中为LED_BUILTIN或13。 RGB :RGB灯引用的是33号引脚,在电路板上标记为33。在 CircuitPython引导加载程序中,被用来当做状态指示灯。通过代码进行控制。它在 CircuitPython 中为board.NEOPIXEL,在 Arduino 中为PIN_NEOPIXEL。
