arduino pro micro板没有支持串口直接烧录代码，不能像arduino uno一样插上电脑写好代码直接一键编译上传...
arduino leonnardo和uno 这两个板子的CPU不一样,Leonnardo用的是ATmega32u4,UNO用的是ATmega328。最大的区别是在USB上面,Leonnardo的USB接口是CPU原生的,而UNO是通过ATmega16u2转的。这导致它们在使用上有一点微小的区别。Leonnardo可以模拟成USB的键盘,鼠标,而UNO不行。如果使用串口功能,由于Leonardo是CPU直接连接USB,...
以下型号为UNO pinMode(pin, mode); 数字IO口输入输出模式定义函数,pin表示为0～13, mode表示INPUT或OUTPUT。 digitalWrite(pin, value) ; 数字IO口输出电平定义函数,pin表示为0～13,value表示为HIGH或LOW。 必须先定义为输入或输出模式digitalWrite才能生效。
大神路过帮忙看看,智..uno板上插L293D扩展板,接四电机在L293D板上M1\M2\M3\M4上,L293D板自已烙上针脚在 A0-A5上,后台A0-A3接ps2接收器,接收器的正负接在L293D板的5V上接电脑USB
Clock Speed : 16 MHz Length: 68.6 mm Width: 53.4 mm Weight: 25 g 3 Power The Arduino Uno can be powered via the USB connection or with an external power supply. The power source is selected automatically. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart...

(recommended) is to use the HARDWARE SPI pins, which are unique// to each board and not reassignable. For Arduino Uno: MOSI = pin 11 and// SCLK = pin 13. This is the fastest mode of operation and is required if// using the breakout board's microSD card.// For 1.44" and 1.8"...
