digitalWrite(2, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second } Code to Note pinMode(2, OUTPUT)- 在使用Arduino的一个引脚之前,你需要告诉Arduino Uno R3它是INPUT还是OUTPUT。 我们使用一个名为pinMode()的内置“函数”来执行此操作。 digitalWrite(2, ...
pinMode(2, OUTPUT) − Before you can use one of Arduinos pins, you need to tell Arduino Uno R3 whether it is an INPUT or OUTPUT. We use a built-in function called pinMode() to do this.digitalWrite(2, HIGH) − When you are using a pin as an OUTPUT, you can command it to...
Blinking an LED with Arduino Blinking an LED with Python Blinking multiple LEDs The next step is blinking multiple LEDS, as an extension of the prior example. That’s not the pattern we’re after with this post, but a baseline for comparison. The code above can be be adapted to control ...
In this tutorial, we will learn how to use GPIO pins of the ESP32 devkit with LED blinking examples using Arduino IDE. Whenever any beginner starts learning about any microcontroller-based development board, Experts always recommend beginners to start with an LED blinking example which is also kn...

Arduino 闪烁LED LED是用于许多不同应用的小型强光灯。首先,我们将学习闪烁LED,即微控制器的Hello World。它就像打开和关闭灯一样简单。建立这个重要的基线将为你提供坚实的基础,以实现更复杂的实验。 必需的组件 你将需要以下组件: 1× Breadboard 面包板...
步驟1. 設置“WAKEUP_SOURCE”,AON定時器:0; AON GPIO: 1; RTC:2,PON GPIO:3,UART/Serial1:4,Gtimer0:5。步驟2. 設置喚醒源。 有 6 個喚醒源,每個都有自己的設置。對於AON 定時器,在“#if (WAKEUP_SOURCE == 0)”部分,設置“CLOCK”和“SLEEP_DURATION”。“CLOCK”可以是 4MHz 或 100kHz。
