okay, let's dive into a comprehensive workshop covering chapters 3 and 5, focusing on practical applications with raspberry pi pico. we'll combine these chapters because they often naturally flow together, dealing with input, output, and basic control flow. this tutorial will incorporate code examples using micropython, explanations of the core concepts, and suggestions for expanding your projects.

*workshop goal:* building a simple interactive system where a button press controls an led's behavior (turning it on, turning it off, or toggling its state).

*chapter overview (combined focus):*

*chapter 3 (digital input):* reading the state of a button (or switch) connected to a gpio pin. this involves understanding how to configure the pin as an input, deal with pull-up or pull-down resistors, and debounce the button to prevent multiple readings from a single press.
*chapter 5 (digital output):* controlling the state of an led (or other simple device) connected to a gpio pin. this involves configuring the pin as an output and setting it high or low to turn the led on or off.
*control flow (integrated):* using `if`, `elif`, and `else` statements to execute different code blocks based on the button's state. this is where the logic of our interactive system comes to life.

*hardware requirements:*

raspberry pi pico
micro usb cable
breadboard
led (any color)
220ω resistor (or similar; range 220-470ω is usually good)
pushbutton (momentary switch)
jumper wires (male-to-male)

*wiring diagram:*

here's a text-based representation of the connections: adjust gpio pins according to your preference. i'm using common/example ones below:



*explanation of connections:*

1. *led:* the led's anode (longer leg) is connected to a gpio pin (e.g., gpio 16) through a current-limiting resistor (220ω). the resistor is crucial to prevent the led from burning out. the led's cathode (shorter leg) is connected to gnd.
