1. 电源（Power）Arduino UNO有三种供电方式：● 通过USB接口供电，电压为5V；● 通过DC电源输入接口供电，电压要求7～12V；● 通过电源接口处5V或者VIN端口供电，5V端口处供电必须为5V，VIN端口处 供电为7～12V。指示灯（LED）Arduino UNO带有4个LED指示灯，作用分别是：● ON，电源指示灯。当Arduino通电时，ON...
5. 输入/输出端口(Input/Output Port) 如图1所示,Arduino UNO有14个数字输入/输出端口,6个模拟输入端口。其中一些带有特殊功能,这些端口如下: ● UART通信,为0(RX)和1(TX)引脚,被用于接收和发送串口数据。这两个 引脚通过连接到ATmega16U2来与计算机进行串口通信。 ● 外部中断,为2和3引脚,可以输入外部
The Uno is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. Revision 3of the board has the ...
