2、输入(INPUT)模式 3、输入上拉(INPUT_PULLUP)模式 (仅支持Arduino 1.0.1以后版本) 在输入上拉(INPUT_PULLUP)模式中,Arduino将开启引脚的内部上拉电阻,实现上拉输入功能。一旦将引脚设置为输入(INPUT)模式,Arduino内部上拉电阻将被禁用。 设置Arduino引脚为输出(OUTPUT)模式 当引脚设置为输出(OUTPUT)模式时,引脚...
Vin电源输入引脚,7-12V It is the input voltage supplied to the board which ranges from 7V to 20V. The voltage provided by the power jack can be accessed through this pin. However, the output voltage through this pin to the board will be automatically set up to 5V. Serial Communication串口...
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...

The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, ...
The first step to reading an Arduino button state is to choose which pin we will connect the button to. For this example, we will use pin 11. Since a button is an input device, we need to declare its pin as an input (do this in the setup function):...
