ESP32 Journey — LED Blinking

Hello, this is my first time to share my story in here. I will share my first experience using ESP32. But we must know about this device first. So, ESP32 is Micro-controller Device with many features like integrated Wi-Fi and Dual-Mode Bluetooth.

First of all, we need another components and device for operating ESP32, check it below.
1. Desktop / Laptop
2. LED Lamp (Optional, because ESP32 has integrated LED Lamp)
3. Micro USB Cable

LED Blink Program

Okay, the above program can get from Arduino IDE Library, and this program is using for LED Blinking with high voltage level condition by 3000 ms, and low voltage level condition by 2000 ms, it means that the LED Lamp will blink with a ratio of 3 : 2.

Work Steps

After you’re sure that your program is working, click Upload button in Arduino IDE, and wait for your program to bo uploaded to your ESP32, don’t forget that you have set your Arduino IDE Port into ESP32 and select DOIT ESP32 DevKit as a board. After it, the LED Lamp will blink according to the program.

Trick

If you use NodeMCU-ESP32 and get some error, try to reuploading the program, and when the Arduino IDE in connecting condition, press Boot button on your ESP32 for 1 to 2 second, release and wait until the program finish uploading.

Its Finish!

This is my first experience, thanks for reading.
