Arduino板上有多个模拟引脚（通常标记为A0-A5），可以用来读取模拟信号。In Arduino, analog input usually refers to the voltage value from the sensor, buttons, or other analog device through the analog pins of Arduino. There are multiple simulation pins on the Arduino board (usually marked as A0-A5...
LEDs can be directly interfaced with the Arduino pins. Arduino GPIO can drive an LED by either sourcing or sinking current through it. However, as the LED must be controlled by the Arduino pin, the pin must be configured as a digital output. If the anode of the LED is connected to the...

The Arduino Uno board has a 10 bits ADC. The resolution can be different if you use other Arduino boards. So, what does 10 bits mean ? Simply that the resolution is 2^10 = 1024. Thus, the value you get when you read data from an analog input pin is between 0 and 1023. ...
