digitalWrite(2,HIGH) - 将引脚用作输出时,可以命令其为HIGH(输出5伏)或LOW(输出0伏)。 输出结果 您应该看到LED亮起和熄灭,如果未看到所需的输出,请确保正确组装了电路,并验证了代码并将其上载到板上。 参考链接 https://www.learnfk.com/arduino/arduino-blinking-led.html...
This is because using delay() blocks other code execution, preventing us from blinking multiple LEDs at the same time. Instead, we utilize the millis() function to manage timestamps effectively. For beginners, managing timestamps while blinking multiple LEDs can be challenging. Fortunately, the ...
Finally, connect two LEDs at the digital pin 7 and 8 and upload the code on your Arduino board and open the Serial monitor. You will see a counter is running once in 500ms with task name as shown below. Also, observe the LEDs, they are blinking at different time...
基于Arduino和LED条形图的电池电压指示器 电池具有一定的电压限制,如果在充电或放电时电压超过规定的限制,电池的使用寿命会受到影响或缩短。每当我们使用电池供电的项目时,有时我们需要检查电池电压水平,是否需要充电或更换。该电路将帮助您监控电池的电压。此Arduino电池电压指示器根据电池电压,通过在10 段LED条形图上...
This code results in a LED (connected to pin 13) blinking on and off repeatedly, with each state (on and off) lasting for one second. More Arduino Tutorials
