We have explained in detail the Raspberry Pi control ultrasonic module ranging (http://www.cnblogs.com/yuemo/p/8888342.html) and ultrasonic control buzzer module audible (http://www.cnblogs.com/ yuemo/p/8906111.html).Today we'll see how to apply all two modules and make an anti-theft device.First look at the connection of each pin (requires seven mother-to-female DuPont line):Ultrasonic module:1.VCC: Connec

Is Raspberry Pi able to use the serial port? The answer is yes. The specific method is as follows: 1. The third, fourth, and fifth ports in the first row of Raspberry Pi are respectively, that is, ports 6, 8, and 10 are respectively, TX and RX, respectively, and connected to the connected device. Note that the TX of
