What is LED Control on an Adapter Board?
- Let’s dive into the world of LED control! So, this adapter board comes decked out with three LEDs that are labeled one, two, and three, and they’re all set up for demonstration purposes.
- This little setup is just the intro to a fun tutorial on using MicroPython to control these LEDs with the Raspberry Pi Pico.
- To really get the most out of this tutorial, it’s important to understand the board’s layout since it shows how we’ll work with GPIO operations..
Why Switch to MicroPython for LED Control?
- In this tutorial, we’re diving into the transition from CircuitPython to MicroPython to control LEDs, and it’s pretty exciting! First off, you’ll find some straightforward instructions that will help you connect your Raspberry Pi Pico to an adapter board without any headache.
- Once that’s done, you’ll get the chance to learn how to control multiple LEDs, which is a great way to boost your understanding of programming, especially when it comes to physical computing..
How to Program LEDs on Raspberry Pi Pico?
- Alright, let’s dive into programming some LEDs on your Raspberry Pi Pico! First things first, you’ll want to import the Pin module from the machine library to get access to those GPIO pins.
- For our setup, we’re using pins 18, 19, and 20 to connect three LEDs.
- It’s super handy to create an array that stores our LED objects, just like you did previously in CircuitPython.
- To get those LEDs shining bright, simply activate them with LED.high(), keep them on for 0.1 seconds, and then switch them off with LED.low().
- Pretty simple, right?.
How did the LED control test go?
- After setting everything up, we saw LEDs one, two, and three light up and dim every 0.1 seconds, which is pretty impressive for timing control! This hands-on demo really shows that our circuit works as intended and that the MicroPython script is doing a great job managing the LEDs.
- Overall, it’s a cool way to see how coding can influence LED behavior and grasp some key electronics concepts..
What did we learn about Raspberry Pi Pico?
- In this session, we dived into the exciting world of the Raspberry Pi Pico and learned how to control an LED using MicroPython.
- The tutorial was super helpful, walking us through some straightforward scripts for LED operations, which really boosted our understanding of GPIO and timing control.
- Plus, there’s more to come! Future sessions are on the way to build on this foundational knowledge and explore even more cool topics.
- Stay tuned for what’s next!.
