Arduino Unois a microcontroller board based on 8-bit ATmega328P microcontroller. Along with ATmega328P, it consists other components such as crystal oscillator, serial communication, voltage regulator, etc. to support the microcontroller. Arduino Uno has 14 digital input/output pins (out of which ...
Arduino Uno上的"pin change"中断是通过PCINT(Pin Change Interrupt)来实现的。PCINT是Arduino Uno上的一个特殊功能,它允许在特定引脚状态变化时触发中断。 在Arduino Uno上,有三个可用的PCINT引脚组,分别是PCINT0、PCINT1和PCINT2。每个组包含多个引脚,可以通过设置相应的寄存器来启用或禁用中断。 具体来说...
Arduino UNO开发板、步进电机、ULN2003驱动板、电位器、USB数据线、面包板及配套连接线等。 实验步骤:(1)根据原理图搭建电路。将ULN2003驱动板的IN1、IN2、IN3、IN4分别连接到Arduino UNO开发板的数字引脚2、3、4、5;驱动板电源输入+、-引脚分别连接到Arduino UNO开发板的5V、GND;电位器的中间引脚连接到Arduino ...
The Arduino Nano Every contains the ATMega4809, a more powerful processor than the one in the Arduino UNO board. This allows you to compile a more advanced program, as it has 50% more program memory than the Arduino UNO ATmega328P. It also has 200% bigger RAM than UNO. If you are us...

利用pinMode()、digitalWrite()和digitalRead()功能,Uno上的14个数字引脚都可用作输入或输出。它们的工作电压为5V。每个引脚都可以提供或接受最高40 mA的电流,都有1个20-50 kΩ的内部上拉电阻器(默认情况下断开)。此外,某些引脚还具有特殊功能:· 串口:0(RX)和1(TX)。用于接收(RX)和发送(TX)TTL串口数据。
On the Arduino Uno board used for this example, pin 13 has an LED connected to it — therefore you should see a tiny orange LED on your Arduino switch on. Click the upload button in the IDE and wait for it to say ‘Done uploading’ before doing anything else. ...
