上传代码后,打开Serial Monitor,监视器将询问位于1-127之间的指纹ID 。 现在Serial Monitor显示屏中输入ID号,并发送,然后按照屏幕指令提示录入指纹。 把希望录入的手指放在传感器上。 一个手指录入成功后,你也可以按照同样的方式再录入其他几个手指的指纹。 指纹读取代码如下: #include int u=0; int relay=5; #if
To use the script open the Arduino serial monitor (or alternative serial monitor on the Arduino port). Then, using an RS485 tranciver, connect another serial monitor to the RS485 port. Entering data on one terminal should be displayed on the other terminal.*/#include"hal/uart_types.h"#inc...

Finally, if you already use a library to handle the I2C bus (Wire.h), TFT, OLED, SPI devices, and Serial UART communication, then it makes sense to use a library to handle the SI473X devices. The PU2CLR Arduino Library can offer more comfort, development agility, and robustness to yo...
You can also send data from the Serial Monitor to Arduino by entering text in the text box to the left of the Send button. Baud rate (the speed at which data is transmitted, measured in bits per second) is selected using the drop-down box on the bottom right. You can use the drop...

实验说明:使用超声波感测与障碍物之间的距离,显示在串口监视器或LCD模块。 实验材料: 测量脉冲持续时间的pulseln()函数 Arduino提供一个测量脉冲时间长度的pulseln()函数,语法格式: Syntax pulseIn(pin, value)pulseIn(pin, value, timeout)此函数将返回微秒单位的脉冲时间,建议用unsigned long类型的变量来存放。
