In the previous tutorial, we learned to blink LED by using the delay method. That method blocks Arduino from doing other tasks. In this tutorial, we are going to learn another method to blink LED without blocking other tasks. The detail instruction, code
LED Blinking Connection Diagram As you can in the above pinout diagram of ESP32, we have a total of 36 GPIO pins, but we will be usingGPIO22as a digital output pin. On different boards, these pins can be located at different locations. Therefore, you need to check its datasheet before...

現在,讓我們嘗試將ESP-WROOM-32用作Arduino。與ESP-WROOM-02一樣,用USB連接了研發板後是不能立即啟動Arduino IDE並寫入程式的。您需要先搭建一個環境再使用。 本文使用的是ESPr Developer 32,這是一款無需焊接即可連接USB直接使用的研發板。任何帶ESP-WROOM-32的研發板都可以,但請務必...

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...
The code (given below) when compiled returned 0 warning and 0 Errors and I flashed it using the default flashing method in Keil. After flashing the LEDs were blinking in a defined timer delay as programmed. Check out the video given below for a complete demonstr...
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
