The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.0). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead ...
The Arduino Nano can be powered via the Mini‐B USB connection, 6‐20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source. Memory The ATmega328 has 32 KB, (also with 2 KB ...

Arduino UNO芯片有两种不同的封装,SMD 和 DIP。因为这里我们使用的是 Arduino Nano 兼容板,所以我们使用的是 32 针 SMD 芯片。以下是MCU的一些规格: 规格: 微控制器:ATmega328P 工作电压:5V 输入电压(推荐):7-12V 输入/输出电压(限制):6-20V 数字I/O 引脚:14 个(其中 6 个提供 PWM 输出) ...

During the development of this project,we discovered on two occasions that the'El Cheapo'Arduino Nanos had started to malfunction.In both cases,diode D1 in the Nano's power supply had'blown'and changed into a high resistance,lowering the supply voltage to less than 2.8V.This diode(an SS1...
所以将程序改为下图这样,对于nano开发板来说没有任何变化。 这个程序函数的含义及用法应该都明白了。它就是定义一个引脚为电源。通过查找,我们知道引脚号是13。 点亮LED小灯的程序里还有一个程序函数: digitalWrite(LED_BUILTIN,HIGH)这是一个程序函数,有两个变量,我们再看一下它的说明: digitalWrite():将数字引脚...

2)选择开发版类型:工具->开发板(以Arduino Nano为例) 3)选择处理器:工具->处理器 Uno只有一种处理器不需要选,Nano处理器有2个版本,新的选ATmega328P,旧的选ATmega328P (old bootloader)。 如果上传失败,提示"avrdude: stk500_recv(): programmer is not responding",一般都是处理器版本不对,切换成另一个...
e. ICSP:in circuit serial programmable (在线串行编程), f. AREF:Reference voltage for the analoginputs (模拟输入的基准电压),数字信号只有两种形态,高电平和低电平。高低电平是通过一个参考电压(AREF)确定的,高于AREF的电平即被认为是高电平,低于AREF的电平即被认为是低电平。Arduino默认的参考电压大约是1.1V...
