Counter and LED Theme Toggle — Micropython Code
Demonstrates a simple counter with theme toggling using MicroPython variables and microcontroller GPIO control (LED indicator).
from machine import Pin
count = 0
isDark = False
led = Pin(2, Pin.OUT)
def updateUI():
print(f"Counter: {count}")
if isDark:
led.value(1)
print("Theme: Dark")
else:
led.value(0)
print("Theme: Light")
def increment():
global count
count += 1
updateUI()
def decrement():
global count
count -= 1
updateUI()
def reset():
global count
count = 0
updateUI()
def toggleTheme():
global isDark
isDark = not isDark
updateUI()

MicroPython is a lean and efficient implementation of Python 3 designed to run on microcontrollers and small embedded systems. It enables developers to write Python code for hardware with minimal overhead while maintaining Python syntax and semantics.
Primary Use Cases
- ▸Embedded systems programming
- ▸IoT device prototyping
- ▸Sensor data acquisition and control
- ▸Educational microcontroller projects
- ▸Robotics and automation scripting
Notable Features
- ▸Lightweight Python 3 interpreter for microcontrollers
- ▸Built-in hardware access modules
- ▸REPL for interactive programming
- ▸Support for various communication protocols
- ▸Extensible with user modules and libraries
Origin & Creator
Created by Damien George in 2013 as an open-source project to bring Python programming to microcontrollers.
Industrial Note
MicroPython is often used in embedded systems prototyping, IoT development, robotics, and research applications, though some production-level devices also use it for lightweight scripting.
