void setup() { pinMode(3, INPUT_PULLUP); }This can be useful when you don’t want a pin to be floating, e.g. when you connect a button to a pin.Note that the analog pins can also be used as digital pins, using
pinMode(pin,OUTPUT);//设置11号接口模式为:输出 digitalWrite(pin,LOW);//输出低电平20ms(>18ms) delay(20); digitalWrite(pin,HIGH);//输出高电平40μs delayMicroseconds(40); digitalWrite(pin,LOW); pinMode(pin,INPUT);//设置11号接口模式:输入 //高电平响应信号 loopCnt=10000; while(digitalRead(pi...
安装完组件后,我们需要上传本文附件中给出的代码。 注意:在上传代码之前,请确保将 Arduino Nano 与您的计算机连接并包含所需的库。 连接后,打开Arduino IDE并上传代码。 完成代码上传后,只需断开 Arduino Nano 与计算机的连接即可。 将PCB 安装到手表上: 在这个项目中,我将发射器握在手中,以便它可以跟踪我的手...
Run the following command in telnet window. This command creates arduino_nano_flash_backup.bin file with content of memory starting at address 0 (on some MCUs FLASH starts on different address than 0, but nRF52840 has FLASH mapped to ...

micros()函数返回Arduino板开始运行当前程序时的微秒数。该数字在大约70分钟后溢出,即回到零。在16 MHz Arduino板(例如Duemilanove和Nano)上,此函数的分辨率为4微秒(即返回值总是4的倍数)。在8 MHz Arduino板(例如LilyPad)上,此函数的分辨率为8微秒。
This module uses the board name (supplied at build time by the -b arduino_nano_33_ble flag) to correctly map Arduino pin names/numbers to the target board. To add board support: This project is structured in a way so as to isolate the variants from the core API. Thus, whenever a ne...
