LED(13号):Arduino专门用于测试LED的保留接口,输出为高时点亮LED,反之输出为低时LED熄灭。 6路模拟输入A0到A5:每一路具有10位的分辨率(即输入有1024个不同值),默认输入信号范围为0到5V,可以通过AREF调整输入上限。除此之外,有些引脚有特定功能 TWI接口(SDA A4和SCL A5):支持通信接口(兼容I2C总线)。 AREF:模拟...
The SCL & SDA pins of Mega 2560 R3 board connects to beside the AREF pin. Additionally, there are two latest pins located near the RST pin. One pin is the IOREF that permit the shields to adjust the voltage offered from the Arduino board. Another pin is not associated & it is kept f...
TWI:Pin 20 (SDA) and 21 (SCL) support TWI communication using the WIRE library. AREF:The reference voltage for analog inputs is used with analogReference(). Reset:for this pin bring the reset line LOW to reset the microcontroller. This pin is typically used w...
