The microcontroller of the board has a circuit inside called ananalog-to-digital converterorADCthat reads this changing voltage and converts it to a number between 0 and 1023. When the shaft is turned all the way in one direction, there are 0 volts going to the pin, and the input value ...

I connected a small LED to pin 11 to see the results of the above PWM code sample. As expected, it operates at a reduced brightness due to the lower voltage. The ‘127’ is a number that can range from 0 to 255, with 255 being the brightest setting. You can use this to set the...
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...
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), which can be used to read analog signals.以下是一个简单的...
这是一个抽象函数，其作用是向指定的数字量接口写入数据。在这个例子中，要写入的数字量接口是LED对应的管脚，写入的数据是目标状态，亮或灭。
在 Arduino 程序中，digitalWrite(LEDpin, state) 是一个函数，用于将电平写入数字引脚。该函数有两个参数：- LEDpin：数字引脚的编号。- state：布尔值，表示要写入的电平。如果 state 为 HIGH，则表示将高电平写入引脚；如果 state 为 LOW，则表示将低电平写入引脚。因此，digitalWrite(LEDpin, state...
The light level on the LDR will change the voltage level on analog pin 0. The analogRead command (see Chapter 6) provides a value that ranges from around 200 when the LDR is dark to 800 or so when it is very bright. This value determines the duration of the LED on and off times, ...
