LED:Pin 13 connects to the built-in LED. When the pis is HIGH value the LED is on, when it is LOW value it's off. TWI:Pin 20 (SDA) and 21 (SCL) support TWI communication using the WIRE library. AREF:The reference voltage for analog inputs is used ...
1)数字I/O:pinMode()、digitalWrite()、digitalRead()函数。 2)在Arduino的UNO、MEGA、ZERO等型号开发板上,LED内置连接在引脚13上,引脚13对于LED来说相当于电源。 3)不管在哪个引脚上,LED_BUILTIN都可以代表正确的引脚号,请学会查阅官方文档。 4) LED电阻极低,需要再加一个电阻,以免烧坏电源或LED灯。 5)GND...
Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to the correct LED pin independent of which board is used. If you want to know what pin the on-board LED is connected to ...
