Since doing Jforum project, there is a very obvious phenomenon, that is, the primary key of each table appears the phenomenon of jumping number. The specific performance: when a number of pieces of data, the automatic growth of the sequence sequence is always increased from a multiple of 200, after this operation, no matter what the currentval is, the interval, always from the next 200 multiples start. For example: The current value of a table is 800, adding 3 records, when Currentval should be

In this project, I'll show you how the Arduino connects to the alcohol detection sensor. Here, I have designed an Arduino Shield circuit board using the Easyeda online PCB designer. The Arduino Alcohol Analyzer detects the amount of alcohol in the breath, and then, by some calculations in the code, we can calculate the amount of alcohol in the breath or blood, and may trigger some alarms. The required Materials Arduino UNO Development BoardAlcohol tester Arduino Shield expansion BoardAlcohol se

(Access port)The default port for HTTP is 80 if the input http://www.baidu.com is equivalent to http://www.baidu.com:80 when accessed. When the project is actually on-line, usually using 80, modify the method as follows:1) Find the Tomcat directory/conf/server.xml2) Modify the value of port to change the port value to 803) then enter the HTTP://127.0.0.1:80 or http://127.0.0.1 access test in the browser Access success ... 3.6.
