In the digital world, a binary value of 1 means HIGH or ON, and 0 means OFF or LOW. However, for Arduino we will stick with HIGH and LOW.On the Arduino Uno board used for this example, pin 13 has an LED connected to it — therefore you should see a tiny orange LED on your ...

The parameters of the function of the function include:The minimum input (in this example is 0)，The input maximum value (in this example 1023)，The minimum output (in this example 0)，The output maximum value (in this example is 100).最后，我们使用`Serial.print()`函数将转换后的值打印到...
For this example, it is possible to use the board's built in LED attached to pin 13. To use an additional LED, attach its longer leg (the positive leg, or anode), to digital pin 13 in series with the 220 ohm resistor, and it's shorter leg (the negative leg, or cathode) to the...
