TheanalogRead()command converts the input voltage range, 0 to 5 volts, to a digital value between 0 and 1023. This is done by a circuit inside the microcontroller called ananalog-to-digital converterorADC. 模拟读 analogRead 命令将输入电压 0 至 5 伏特转换到数字值域,从 0 至 1023.这是通过...
2、读取模拟电压 - Read Analog Voltage Reads an analog input and prints the voltage to the Serial Monitor. 读取模拟输入并打印电压值到串口监视器。 This example shows you how to read an analog input on analog pin 0, convert the values from analogRead() into voltage, and print it out to the...
connected to the a common output - their inputs are also connected. These act as current source and sinks - to allow a large fan out. In normal use the logic driving these inputs is logic high or low. If you drive them at the mid range voltage (think analogue input at Vcc/s) then...
0049 volts mV) per unit.The input range a 26、nd 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...
The Leonardo ETH is a microcontroller board based on the ATmega32U4 (datasheet) and the new W5500 TCP/IP Embedded Ethernet Controller (datasheet). It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a RJ45...
Arduino senses the input voltage, converts the analog voltage into digital value and displays the value through a liquid crystal display. The arduino also calculate the value and indicate the voltage range by turning on LED lights. A green LED indicates 0.1 to 5 volt range which is low ...

37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...
If using more than 12V, the voltage regulator may overheat(过热)and damage the board. The recommended range(推荐范围值)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 ...
