If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts. The power pins are as follows: Vin. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection...
An Arduino UNO microcontroller based digital voltmeter has been designed and developed with liquid crystal display and voltage range indicator. A regulated low voltage power supply circuit (5 volt) has been developed to power up Arduino microcontroller. Arduino senses the input voltage, converts the ...
on the line, there are only 15 equal-length segments. Therefore, the scale factor for a 4-bit analog-to-digital converter is 5V/15 because the 5V range is divided into 15 intervals. By analogy, the correct scaling for a 10-bit analog to digital converter having a maximum input range ...

To change the values from 0-1023 to a range that corresponds to the voltage the pin is reading, you'll need to create another variable, afloat, and do a little math. To scale the numbers between 0.0 and 5.0, divide 5.0 by 1023.0 and multiply that bysensorValue: ...
The input range and resolution can be changed using analogReference (). It takes about 100 microseconds s) to read an analog input, so the maximum reading rate is about 10,000 times a second. 从指定的模拟引脚读取值。 Arduino 主板有 6 个通道( Mini 和 Nano 有 8 个, Mega 有 16 个),...
analogWrite(pin, value) 在已有的引脚上使能软件PWM功能。PWM可以用在引脚0~16。调用analogWrite(pin, 0) 可以关闭引脚PWM。取值范围:0~ PWMRANGE,默认为1023。 PWM 范围可以使用analogWriteRange(new_range)语句来更改。 PWM 默认频率:1KHz。使用analogWriteFreq(new_frequency) 可以更改频率。
