Introduction to MicroPython with Thonny IDE and ESP32

What is MicroPython?

MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimized to run on microcontrollers and in constrained environments. MicroPython Documentation

What is Thonny IDE?

Thonny is a Python IDE for beginners. It has a simple and clean interface, and it is designed specifically for teaching and learning programming. Thonny IDE

What is ESP32?

ESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. ESP32 Series

Getting Started

Install Thonny IDE: Download and install Thonny IDE from the official website. It's available for Windows, macOS, and Linux. Thonny IDE
Set up ESP32 with MicroPython: You'll need to flash the MicroPython firmware onto your ESP32 board. You can do this using a tool like esptool.py. Once you've flashed the firmware, you can connect to the ESP32 using Thonny. Getting Started with ESP32 and MicroPython
Write Your First Program: In Thonny, you can write Python code in the editor on the left and see the output in the shell on the right. Try writing a simple program like blinking an LED or printing to the serial console.

from machine import Pin, Timer

led = Pin(2, Pin.OUT)  # create output pin on GPIO2
tim = Timer(-1)        # create software timer

def blink(timer):
    led.toggle()        # toggle LED

tim.init(freq=2.5, mode=Timer.PERIODIC, callback=blink)  # blink LED at 2.5Hz

This code will blink an LED connected to GPIO2 of the ESP32 at a frequency of 2.5Hz.

Basic Python Concepts

Variables: Variables are used to store data. They can hold different types of values, like numbers, strings, and lists.

x = 10  # integer
y = "Hello, World!"  # string
z = [1, 2, 3]  # list

Functions: Functions are reusable blocks of code that perform a specific task. They help break down complex programs into smaller, more manageable parts.

def greet(name):
    print(f"Hello, {name}!")

greet("Alice")  # prints "Hello, Alice!"

Control Flow: Control flow statements, like if/else and for/while loops, determine the order in which code is executed.

for i in range(5):
    print(i)  # prints numbers from 0 to 4

x = 10
if x > 0:
    print("x is positive")  # prints "x is positive"
