# 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](https://docs.micropython.org/en/latest/index.html)
## 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](https://thonny.org/)
## 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](https://www.espressif.com/en/products/socs/esp32)
## Getting Started
1. **Install Thonny IDE**: Download and install Thonny IDE from the official website. It's available for Windows, macOS, and Linux. [Thonny IDE](https://thonny.org/)
2. **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](https://randomnerdtutorials.com/micropython-programming-esp32-esp8266/)
3. **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.
```python
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.
```python
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.
```python
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.
