Raspberry Pi Pico W LESSON 1: Write Your First Program for Absolute Beginners¶
Description¶
This video will walk you through the process of setting up MicroPython on your Raspberry Pi Pico W and installing Thonny, a user-friendly development environment, on your computer. With Thonny, you’ll be able to communicate directly with your Pico W. During this brief introductory session, you’ll create your first four programs and be given a homework task to complete. The class is perfect for total beginners—no prior experience is needed. My aim is to empower you with the skills to tackle these kinds of projects on your own, in a supportive and approachable way.
Hardware¶
# |
Component |
Description |
Tech Spec |
|---|---|---|---|
1 |
Pi Pico W |
A microcontroller board with Wi-Fi capability, used to control the LED. |
3.3V operation, RP2040 CPU |
2 |
LED |
A light-emitting diode that blinks on and off as controlled by the Pico W. |
2V forward voltage, 20mA |
3 |
Capacitor |
Smooths out voltage fluctuations to stabilize the circuit. |
10µF, 16V (electrolytic) |
4 |
Breadboard |
A solder-less platform for building and testing the circuit layout. |
400 tie-points, 2.54mm pitch |
5 |
Wire |
Connects components on the breadboard to complete the circuit. |
22 AWG, solid core |
