当一个引脚通过pinMode配置为OUTPUT,并通过digitalWrite设置为LOW时,引脚为0V。在这种状态下,它可以 倒灌 电流。例如,点亮一个通过串联电阻连接到+5V,或到另一个引脚配置为OUTPUT、HIGH的的LED。 数字引脚(Digital pins)定义,INPUT和OUTPUT 数字引脚当作 引脚(Pins)配置为输入(Inputs) Arduino(Atmega)引脚通过pinMod...
The Arduino Mega 2560 is 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, ...
void setup() { // set pins 2 through 13 as outputs: for (int thisPin = lowestPin; thisPin <= highestPin; thisPin++) { pinMode(thisPin, OUTPUT); } } void loop() { // iterate over the pins: for (int thisPin = lowestPin; thisPin <= highestPin; thisPin++) { // fade the ...
PWM:Pins 2 to 13 and 44 to 46 provide 8-bit PWM output with the analogWrite() function. SPI:Pins 50 (MISO), 51 (MOSI), 52 (SCK), 53 (SS) support SPI communication using the SPI library. They are also broken out on the ICSP header, which is compatib...

But IMHO if I was upgrading from an UNO to a mega I would be happy to upgrade the shield to a 6axis. ( the stepper drivers would be transferable ) Due/Mega shield should be achievable the I2C pins on the Due would need to be kept clear so an I2C EEPROM could be used. The steppe...

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...
AnalogWriteMega*/// These constants won't change. They're used to give names to the pins used:constintlowestPin=2;constinthighestPin=13;voidsetup(){// set pins 2 through 13 as outputs:for(intthisPin=lowestPin;thisPin<=highestPin;thisPin++){pinMode(thisPin,OUTPUT);}}voidloop(){// ...
