So far you've learned to control LEDs with code, which is one use of Arduino'soutputs. This lesson builds on outputs by addinginputs. Your Arduino board can be programmed to listen to electrical signals and take actions based on those inputs. We'll put together a digital input circuit w...
1 10.1调声函数 ❖调声函数tone()主要使用在Arduino连接蜂鸣器或扬声器发生的场合，其实质是输出一个频率可调的方波，以此驱动蜂鸣器或扬声器振动发声。1.tone()功能：在一个引脚上产生一个特定频率的方波（50%占空比）。语法：tone(pin,frequency)tone(pin,frequency,duration)参数：pin，需要输出方波的引脚。
Chapter 5. Advanced Input and Output What you have just learned inChapter 4are the most elementary operations we can do in Arduino: controlling digital output and reading digital input. If Arduino were some sort of human language, those would be two letters of its alphabet. Considering that th...
Analog Input and Output on an ArduinoIn Chapter 14, we learned how to do basic digital input and output with an Arduino using its I/O pins. In this chapter, we will cover how to do analog input and output as well.doi:10.1007/978-1-4842-5979-5_15Jonathan Bartlett...

pinMode(PIN_D6,OUTPUT); The first parameter is the pin number to configure and the second parameter must be either INPUT or OUTPUT. Often pinMode() is used in the setup() section to configure all the digitial pins that are used and they simply remain that way. However, you may change...

output capabilities of the Arduino microcontroller board. Microcontrollers are inherently digital devices that employ discrete binary values, 0 and 1, corresponding to the voltages 0 V and (in our case) 5 V, respectively. The discrete value of 0 V is considered a “Low” value, logical 0, ...
