As an extension of the same can we control four computer cooling Fans with PWM i/p to PWM o/p of Arduino UNO also using the LCD shield with buttons to set individual speed for each fan.Seek your advice, thanks. Reply ColtPtrHun 4 years ago Hello there! I have a few questions ...
Power up your Arduino by connecting your Arduino board to your computer with a USB cable (or FTDI cable if you're using an Arduino Pro). You should see the an LED labeled 'ON' light up. (this diagramshows the placement of the power LED on the UNO). ...
In the diagram below we show an UNO board that has D13 as the LED_BUILTIN value. 如果想用该代码点亮一个外接 LED,需要连接电路,需要将电阻的一段连接到 LED_BUILTIN 常量对应的数字针。连接 LED 的长脚(正极脚,也叫阳极)到电阻的另一端。连接 LED 的短脚(负极脚,也叫阴极)到接地 GND。下面的...
