Arduino Uno和Arduino Mega的GPIO引脚描述及连接方法说明书
In some other Arduino boards, like Mega, there are several different available UARTs. But for Arduino Uno, you only have one. If however, you want to use more UARTs, you can always do that with theSoftwareSerial library. This library allows you to use any other digital pins for UART pur...
Here you will find all of the technical documentation and support files for the Arduino Mega 2560 Revision 3. Arduino Comparison Chart: Boards & Modules Eagle Files Download Schematics I/O- All 54 digital bins on the Arduino 2560 can either be used as an input ...
Arduino Mega Pin Configuration The pin configuration of thisArduino mega 2560board is shown below. Every pin of this board comes by a particular function which is allied with it. All analog pins of this board can be used as digital I/O pins. By using this board, the Arduino mega projected...
Reset pin None of the megaAVR-0 microcontrollers needs the reset line to be reprogrammed over the UPDI interface. This means that the reset pin can be used as a GPIO pin instead! There's no need for a high voltage programmer to turn that pin into a reset pin again either. If you hav...
Unfortunately, the LED may turn on when it is not supposed to due to a floating voltage on pin 11. To overcome this problem, you may need to connect a1 Megaohmresistor between pin 11 and GND. Serial Communication: A Way To See What Your Arduino Is Doing ...
