Micropython Basics: Key Micropython Modules

MicroPython comes with a collection of built-in modules that make it easy to interact with hardware, manage timing, connect to networks, and even send data to the internet. Understanding these modules is essential to writing practical MicroPython programs for embedded systems. Here are some of the most commonly used modules you’ll encounter: machine — Hardware […]

Micropython Basics: Analog Output

Analog Output (PWM) Unlike true analog signals, most microcontrollers — including ESP32, ESP8266, and Raspberry Pi Pico — do not have real analog output pins. Instead, they use a technique called PWM (Pulse Width Modulation) to simulate analog behavior by rapidly switching a digital pin on and off. The ratio of the ON time to […]

Micropython Basics: Analog Input

So far, you’ve learned how to work with digital inputs and outputs — signals that are either ON or OFF, HIGH or LOW. But what if you need to measure values that change gradually, like light intensity, temperature, or knob position? That’s where analog inputs come in. Using MicroPython’s ADC (Analog-to-Digital Converter) feature, your microcontroller […]

Micropython Basics: Digital Inputs

Now that you can save and manage your scripts, it’s time to interact with the real world using digital inputs. One of the simplest and most common examples is reading the state of a push button to control an LED. In MicroPython, digital inputs and outputs are handled through the machine module, which provides access […]

Micropython Basics: Digital Output

Before working with sensors or complex hardware, it’s important to master digital outputs. A digital output allows your microcontroller to control external components by switching its GPIO pins ON (HIGH) or OFF (LOW). The most common way to start learning digital output is through an LED — a simple visual indicator that helps you confirm […]
