serial port: read a value from the analog input pin and use this value to control the LED lightAnalog signal Input: Use a potentiometer to control the blinking of the LEDs.Analog output [Mega]: Use the Arduino Mega board to allow 12 LEDs to fade in one after the other.Analog signal Calibration: Set the maximum and minimum value of the sensor output analog signal to achieve the desired effect.LED brightness fade: Use the pulse width pin (PWM pin) to weaken the brightness of an LED.Signal smoothi

complete ticket transaction processed within less than 100 ms. Therefore, the user does not have to stay at the reader antenna to form a high pass rate, reducing the boarding time of the bus. During transactions, Mifare cards can be left in the wallet, and even coins in the wallet are not affected. Security:Security focuses on fraud prevention. Mutual random number and response authentication, data encryption, and packet authentication checks and prevents various cracking and tampering, making

Excel Secondary Development Series Previously we talked about the Excel programming model and common Excel operations. In this section, I will explain how to create an Excel application-level secondary development program. Many useful materials can be found on Microsoft's basic website. Here we mainly talk about the secondary development of Office projects: http://msdn.microsoft.com/zh-cn/library/cc668205.aspx. 1. Create an Excel Project, for example:

Java Collection series [3] ---- HashMap source code analysis, java ---- hashmap We have analyzed the ArrayList and ArrayList sets. We know that ArrayList is implemented based on arrays, and ArrayList is implemented based on linked lists. They each have their own advantages and disadvantages. For example, ArrayList is superior to lateral list when locating and searching for elements, while lateral list is su

PHP Learning Series (1) -- string processing functions (3), php Functions 11. The crc32 () function calculates the crc32 polynomial of a string. Generate the 32-bit Cyclic Redundancy checksum polynomial of the string parameter. This function can be used to verify data integrity.Syntax: crc32 (string) Note: Because PHP integers are signed, many crc32 verification codes return negative integers, so you need t
