合宙ESP32C3开发板上丝印为D5的LED,所对应的GPIO口为GPIO13,稍微修改Blink工程代码,添加如下定义: #define LED_BUILTIN (13) 完整代码如下: #define LED_BUILTIN (13) // the setup function runs once when you press reset or power the board void setup() { // initialize digital pin LED_BUILTIN ...
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW 低电平为LOW,灭灯 delay(1000); // wait for a second,同上。 } 如果编译出现类似的错误,error: 'LED_BUILTIN' was not declared in this scope,原因是LED_BUILTIN没有被申明,你可以直接使用esp32的pin number直接更换,...

You can test your Arduino® setup on the ESP32 using the “Blink” example sketch in File > Examples > 01.Basics. Define the LED_BUILTIN pin as pin 5 to use the onboard LED. ThingSpeak Setup To use ThingSpeak , you must have a user account and a created channel. Each channel has...
