}Code language:Arduino(arduino) The same code is used for both Arduinos. We can connect the two Arduinos on two separate computers but also we can use a single computer. In that case, once we connect the first Arduino to the computer, we need to select the model and the COM port ...

(一)Arduino和HC-05连接 注意:Arduino通过TX与HC-05进行通信,而Arduino的电压为5V,HC-05的允许电压为3.3V。短时间通信无妨(长时间可能烧毁HC-05)<接分压电路> U =5*20/30=3.3V I= 5V/(10K+20K) =0.16mA (二)Arduino和HC-05和手机通信

在所有管脚连接完成之后,首先使用Arduino MEGA 2560板卡发出一个持续时间至少为10微秒的TTL高电平信号给超声波测距模块(以后简称模块),这时模块进入测量模式,并以40kHz的频率发出8个连续的方波脉冲,然后当模块接收到回波后会返回一个PWM信号,该信号高电平持续时间为从发出超声波到接到回波所需要的时间。
Next, create a setup function for the Arduino serial port. The Arduino Pro Micro has two USART ports: Serial and Serial1. Both are used in the code; one for communicating with the HC-12 module and the other with USB Serial Port. The default baud rate of HC-12 is 9600. Use the same...
