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 bo
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...
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...

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 ...
On Windows,use the USB cable to connect your PC and the Arduino board and wait for theFound New Hardware Wizard to appear. If you are using anUno board, let the wizard attempt to find and install drivers. It will fail to do this (don’t worry, this is the expected behavior). To ...
