这是一个数字输入,意味着开关要么在闭合状态(从 Arduino 中看到输出 1 或者 HIGH)要么为断开状态(从 Arduino 上看到输出 0 后者 LOW),不会显示之间的值。 The first thing you need to do in the main loop of your program is to establish a variable to hold the information coming in from your switc...
This example shows you how to read analog input from the physical world using a potentiometer. Apotentiometeris a simple mechanical device that provides a varying amount of resistance when its shaft is turned. By passing voltage through a potentiometer and into an analog input on your board, it...
The function EEPROM.read() is used to read a particular data byte from the internal EEPROM of the Arduino’s microcontroller. The function has a single parameter which is the address from which the data should be read from. The function has a return value which is the actual data byte whi...

This is because ORing adds the bits into the same variable (leaving the others unaltered), whereas ANDing isolates each bit from the rest (for output).How fast is Arduino shiftIn()? The function uses digitalRead() so it should be similar to the speed of digitalWrite() - in that link ...

disp_control– is a boolean variable used to control the number of times program control executesPrintData()function. We are printing RFID card data on Serial Monitor only when a new card is read. So that’s all about the variables used in the program. I think the program is self explana...
Today we will be learning how to make a read-only property in C#, so it can only be read and not modified. ADVERTISEMENT Declare the Read-Only Property on a Variable When Initializing in C# We have worked on the class CAR for the last two articles. Let’s use the same class and try...
For simplicity, the code is divided into two portions the first portion of code is to check only the working of the I2C display and the second portion is where we implemented little FS, Testing the 16X2 I2C LCD with Arduino: We start our code by including all ...
