Next, initialize digital pin 2, the pin that will read the output from your button, as an input: 然后初始化数字针 2,该针会动按钮读取输出,并作为输入: pinMode(2,INPUT); Now that your setup has been completed, move into the main loop of your code. When your button is pressed, 5 volt...

. Once opened, ask the Arduino to read the contents of the file with SD.read() and send them over the serial port. After all the contents of the file are read, close the file with SD.close() . Note that pin 4 is default Chip Select (CS) pin for most boards. To set CS for M...
In this project you’ll learn how to read from a digital I/O pin, using the digitalRead() function.Digital I/O pins on the Arduino Uno board are the ones on the USB port side of the board, and they might also be marked as digital on the pins, like in my case:...

The Arduino pins can be configured as INPUT, OUTPUT, or INPUT_PULLUP. When a pin is configured as INPUT, a voltage greater than 3V and a voltage greater than 2V is read as logical HIGH in 5 and 3.3V boards, respectively. A voltage less than 1.5V and a voltage less than 1V is re...
When a pin is configured as an input, you can read it with digitalRead(), which returns 0 if the pin is low, or 1 if the pin is high. The result is usually used with anifstatement to run different code depending on the voltage on the pin. ...
functions for Arduino, which work faster than the 'built-in' functions while remaining as easy to use and portable as the original ones. If you just want to try the new functions, feel free to go directly to "Using the code" section, otherwise, read on for some introd...
enables read and write access to the file, starting at the end. If a file "test.txt" 1. Name the instance of the opened file "myFile". Once opened, use myFile.println() 1. Again, open the file with SD.open() 1. . Once opened, ask the Arduino to read the contents of th...
