Original link: https://www.arduino.cc/en/Tutorial/Knock Percussion detectionThis tutorial shows you how to use a piezoelectric sensor to detect vibrations, such as knocking, tables, or other solid surfaces. A piezoelectric sensor is an electronic device that generates voltage when it is physically deformed by vibration, sonic, or mechanical strain, and similarly, when you apply a voltage to a piezoelectric transducer, it vibrates and produces ton
GE switches are worth learning a lot. Here we will introduce you to the future development direction of GE switches, which are serious experts. The reporter interviewed experts in the field of GE switches on hot topics, including technical experts from equipment suppliers and network construction experts from users. Each of them holds one word, and their points of view are roughly divided into two schools. In our answers to the following questions, we will separate the two comments with A and B.
The advent of the information age means that we have more and more requirements for the speed of the network, we have to transfer files through the network, but also through the network to hold video conferencing; We not only need to send and receive mail, but also quickly download a variety of video, audio files. And with the speed of the network from the original one trillion, 10 trillion, a few years ago, hundreds of trillion, developed to today's gigabit

the following: Only the Fast Ethernet hybrid network module can support these two wan interface cards. The network modules supporting these two interface cards are as follows: NM-1FE2W, NM-2FE2W, NM-1FE1R2W, NM-2W. The Ethernet hybrid network module does not support the following features: NM-1E2W, NM-2E2W, NM1E1R2W. 19. What is the maximum rate of synchronization supported by Cisco3600 series routers (4A/S, NM (8A/S network module and WIC (2A/s wan Interface Card? These network modules and WAN
provides sufficient performance to support this application. Small companies are typical representatives of this environment. They have basic network facilities or relatively simple IT needs. The software systems it runs may include text processing, workbooks, inventory management, billing management, and document storage systems. Another possible scenario is that users with relatively short lease periods cannot foresee switching to over Mbps Ethernet during their stay. In this case, cat5e is s

The MCE1 on the Cisco 7000 can be configured as E1, CE1, while the E1, CE1 on the Cisco 2600/3600 only supports its own functionality. 28. Does the CISCO 2600 series routers support inter-VLAN routing, and what are the requirements for iOS software? In Cisco (2600 series routers, only Cisco2620 and Cisco2621 can support inter-VLAN routing (The Hundred-Gigabit eloquence supports

If Inter-VLAN routing is supported, IOS software must include the IP Plus feature set.6. What are the differences in hardware between the Cisco3660 router and the 3620/3640 router?The differences are as follows:* The basic configuration of the Cisco3660 router includes one or two 10/100 M Adaptive Fa
Raspberry Pi-SonicPi (sound programming) Sonic Pi is an open-source programming environment designed to explore and teach programming concepts by creating sound production music processes. The Code executed by Sonic Pi is based on Ruby, which is a beautiful and concise programming language. This means that you can write a lot of code without having to worry too much about syntax and braces-though important
Sonic Vegas 5.0 is a professional video and voice editing software. Clips of the film, special effects additions, material synthesis, final rendering can be coherent. Combined with a simple interface and a number of highly efficient and excellent features, users can quickly edit the rich image, can be compared with premiere and after effects comparable. Both professionals and individual users can be easily used for their simple interface. About
