Controlling a switch on the Raspberry Pi Pico using CircuitPython

Getting started with the Raspberry Pi Pico is pretty exciting! First, you’ll want to pop the Pico into the adapter board so you can control an LED using a button.
The whole idea here is to switch the LED on and off just by pressing that button on the board.
Oh, and don’t forget, you’ll need to clear out any existing code from your last session to make sure you’re starting with a clean slate..

In this session, we’re diving into how to control an LED and key configuration on the Raspberry Pi Pico.
First off, we’re focusing on recording interactions without the hassle of specific time settings; instead, we’re just relying on the application settings to manage the whole process.
Now, for the LED, we’re linking it to GPIO pin 25 and setting it to a down state in output mode, which is pretty neat because it lets the LED send signals.
On the other hand, the key we’re using is set to input mode and tied to GPIO4, so it can receive signals as needed.
And don’t forget, to get everything running smoothly, you’ll need to run the Excel setup and confirm your settings by hitting ‘y’ for optimal performance.
So, let’s get started and make sure everything is configured correctly!.

So, let’s break down how button logic works! When you set up the input and pull-up settings, your circuit hangs out in a true state (1) when the button isn’t pressed.
But the moment you press that button, the state flips to false (0), meaning it’s now low.
Now, if you apply a ‘not’ logical operation while the button is pressed, it’ll switch things back to true.
This cool functionality means you can perform different actions based on whether you’re pressing or releasing the button..

In this demonstration, we can see how pressing the key on the Raspberry Pi Pico makes the LED light up, which really shows that our logic is spot on! When you let go of the key, the LED turns off, and that’s a clear example of how the control mechanism works.
This interactive setup makes it super easy to toggle the LED on and off just by pressing and releasing the key.
Plus, it really highlights how handy CircuitPython is for controlling switches on the Raspberry Pi Pico, proving its practical use in real-world applications..

So, as we wrap things up, it’s clear that we’ll be diving into a new topic soon! It’s all about continuity , which means we’re going to keep learning and exploring together.
Plus, there’s a lot of excitement brewing for the future discussions and demonstrations that are on the horizon.
Stay tuned!.
