Introducing Arduino Nano ESP32 With WiFi & Bluetooth

Introducing: Arduino Nano ESP32

Arduino has released the Arduino Nano ESP32, a board that stands out from the rest due to its unique features. This board offers both Bluetooth and WiFi capabilities. One of the most appealing features of this board is that it supports MicroPython. Let’s explore how this board works and what makes it special.

How Does It Work:

Before we begin, it’s important to note that this board is based on MicroPython. To get started, you first need to install Arduino’s new editor called ‘Arduino Lab for MicroPython’. After installing this editor, you must then install the firmware onto your ESP32 board.

Here are the steps in detail:

Install the ‘Arduino Lab for MicroPython’ editor from the Arduino website.
Connect your ESP32 board to your PC/Laptop.
Install the firmware on your ESP32 board via the editor.
Until you install the firmware on your board, it won’t operate as expected.

Arduino Nano ESP32 Code :-

Once everything is set up, you can connect your Nano ESP32 and run the following code:

from machine import Pin
import time
myLED = Pin(0, Pin.OUT)
while True:
myLED.value(0)
time.sleep(1)
myLED.value(1)
time.sleep(1)

As soon as this code runs, the LED on your Nano ESP32 will turn ON for 1 second and then OFF for 1 second, in a repeating loop.

Switching to Bootloader Mode:

If, after uploading the MicroPython firmware, you wish to use the board with the Arduino IDE, you will need to switch the board to BOOTLOADER mode. Here’s how:

Press the Reset button on your board once.
Press it again, and as soon as the green LED starts flashing, your board will enter bootloader mode.
Now, you can use it with the Arduino IDE just like any other Arduino board.

This cycle allows developers to write MicroPython code, test it rapidly on the board, and, if necessary, transition back to the familiar environment of the Arduino IDE. The Arduino Nano ESP32 thus offers a great deal of flexibility and is a powerful tool for IoT projects.
