There are 16 analog pins incorporated on the board labeled as A0 to A15. It is important to note that all these analog pins can be used as digital I/O pins. Each analog pin comes with 10-bit resolution. These pins can measure from ground to 5V. However, the upper value can be chang...
TheArduino Mega 2560is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and ...
一些板卡(例如Arduino Mega 2560)具有更多的外部中断。如果有其中之一,则可以保留SW引脚的连接,并在草图下方延伸以包括按钮的代码。 Arduino代码 这是演示在读取旋转编码器时使用中断的示意图。 // Rotary Encoder Inputs#define CLK 2#define DT 3intcounter=0;intcurrentStateCLK;intlastStateCLK;Stringcurrent...

arduino mega的供电系统有两种选择,usb直接供电或外部供电。电源供应的选择將会自动切换。外部供电可选择ac-to-dc adapter或者电池,此控制板的极限电压范围为6v~12v,但倘若提供的电压小于6v,i/o口有可能无法提供到5v的电压,因此会出现不稳定;倘若提供的电压大于12v,稳压裝置则会有可能发生过热保护,更有可能损坏arduin...
