Free, in your browser, every step checked by the simulator. Chapter 1 project ### Buttons and if Read a button with a pull-up, make a choice with if and else, and print only when something changes. Open it in the simulator Chapter 2 project ### Read a sensor with the ADC A knob on GP26 turns into a number with ADC, and that number sets the LED brightness. Then a little math turns it into a percent. Open it in the simulator Chapter 3 project ### I2C to an OLED screen Two wires carry a whole conversation: find the OLED and a weather sensor on I2C, then draw text on the screen.

Functions, if, loops, random and the board clock come together in one game that keeps your best score. 0 of 4 steps Syllabus ## Every lesson in the course All 7 lessons, in order, each with what it covers. Any of them opens in the editor right away. Chapter 1 ### First Python - Blink, and talk to the board Your first MicroPython program blinks two LEDs, then you type Python straight into the board with the REPL. - Buttons and if Read a button with a pull-up, make a choice with if and else, and print only when something changes. Chapter 2 ### Loops and sensors - Loops and a PWM fade A for loop with range() steps an LED from dark to bright and back, using PWM to fake the levels in between. - Read a sensor with the ADC A knob on GP26 turns into a number with ADC, and that number sets the LED brightness. Then a little math turns it into a percent. Chapter 3 ### Bigger programs - Lists and functions on an LED bar Six LEDs in one list, and two small functions that turn a number into a moving dot or a growing bar. - I2C to an OLED screen Two wires carry a whole conversation: find the OLED and a weather sensor on I2C, then draw text on the screen. Chapter 4 ### Boss game - Boss game: reaction timer Wait for the light, then hit the button. Functions, if, loops, random and the board clock come together in one game that keeps your best score. Keep going ## The next course on your track MicroPython on the Pico is part of the embedded track, a ladder of courses from zero to expert. Next course ### Connected devices WiFi, APIs, a web server, MQTT, ESP-NOW and BLE on the ESP32, and a device that keeps going when the network does not. Open the next course Track ### Embedded track Arduino, ESP32, Raspberry Pi Pico and STM32: pins, timing, buses, motors, WiFi, registers and debugging, every lesson checked on a simulated board. See every course on the track Kits ## Build it on your bench too Every lesson runs in the simulator with nothing to buy. When you want the real thing, these kits have the parts. Have a kit already? ### Find your kit Pick the starter kit you own and run every lesson in its manual with the same parts on the same pins. See every kit Questions ## About MicroPython on the Pico Is MicroPython on the Pico free? Yes. All 7 lessons of MicroPython on the Pico are free and run in your browser, with nothing to install and no parts to buy before you start. Do I need a real Raspberry Pi Pico? No. Every lesson runs on a simulated Raspberry Pi Pico with its parts on the canvas, and the simulator checks each step as you go. When you want to build it for real, the same wiring and code work on a real board. How long does MicroPython on the Pico take? About 3 hours: 7 lessons in 4 chapters, each one a few short steps. Your progress is kept, so you can stop after any lesson and pick up where you left off. What will I build? Each chapter ends in a project that puts it together: Buttons and if, Read a sensor with the ADC and I2C to an OLED screen. Where do I start? With "Blink, and talk to the board", and each lesson builds on the one before it. New to circuits? Electronics basics is the course that starts from zero.
