Arduino Unois a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everyth...
AREF. Reference voltage for the analog inputs. Used with analogReference(). Reset. Bring this line LOW to reset the microcontroller. Typically used to add a reset button to shields which block the one on the board. Communication The Arduino Uno has a number of facilities for communicating with...
噢,原来在注释里有说明,多数开发板都有可控制的LED小灯,在UNO、MEGA和ZERO 这三个开发板上的led灯输出引脚为13,MKR1000上的可控LED小灯连接的引脚为6,在Arduino里面不管开发板可控制这颗集成的LED的引脚号是多少,在程序里面都可以用关键词:LED_BUILTIN来代替,在Arduino设置好开发板型号以后,LED_BUILTIN就代表了...

voidsetup() { pinMode(11, OUTPUT); analogWrite(11,127); //Operates at a reduced voltage and current. } 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 ...
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...
Serial.print("Current:"); Serial.println(cur); } The main function of the code is to read 1000 times (with a delay of 1 msec) the voltage from the analog input A0, average this value and then converting it into a current. Constants and Variables ...
