The Seeed Studio XIAO ESP32C3 is a tiny programmable computer. It can switch on lights, listen to sensors, control gadgets, and even communicate using Wi-Fi and Bluetooth.

In this tutorial, we will go over its pins and what they do.

SPI (Serial Peripheral Interface) is a communication method that allows electronic devices to exchange information quickly.

In this lesson, you will learn how SPI works, what wires it uses, and why it is useful. People commonly use SPI to connect microcontrollers to sensors, displays, and memory modules.

Here’s a list of all the parts you need to build the table tennis scoreboard. Each part links to Amazon. If a link doesn’t work, don’t worry - we’ve also added tips on how to find a replacement.

In this self-paced, beginner-friendly online course, you will learn how to create a memory testing game. And don’t worry if you’ve never wired a circuit or touched an ESP32 before. We guide you from the very first step all the way to powering on your finished game.

By the end of this journey, you’ll both have learned how to read resistor color codes and work with common electronic components - all while building something that looks impressively “advanced” but is totally achievable for beginners.

Before you jump into the build videos, this first lesson gives you a clear picture of what you're creating - and what materials you’ll need to make it happen. We want you to have full confidence in what you’re investing in. There are no surprise expenses later: everything required is listed upfront, along with tips on where to buy each part.

When you need a loud, straightforward alert for a project, like a timer, a security alarm, or a button-press confirmation, you don't always need complex music or variable tones. Active buzzers are simple "plug-and-play" components. Give them power, and they instantly make noise, saving you code and wiring hassle.

In this quick tutorial, you'll discover:

• What an active electronic buzzer is and how it differs from a passive one.

• How to identify the anode (+) and cathode (-) pins.

• How to wire and trigger an active buzzer using simple DC power or a microcontroller.

This tutorial covers the fundamentals of LEDs: how they function, how to identify their terminals, and how to safely power them without damaging the component.

Understanding LEDs is essential because they are the standard light source in modern electronics. Used in phones, monitors, custom PC builds, and basic microcontrollers like Arduino or ESP32.

Push buttons allow users to interact with electronic circuits. Whether you are building an Arduino project, a game controller, or a custom gadget, you need these buttons to trigger actions, start programs, or change settings.

What you will learn:

1. What a tactile push button is.

2. How the 4 pins connect internally.

3. How to place the button correctly on a breadboard.

A breadboard is your best friend for prototyping. It lets you test circuits safely, make mistakes, pull wires right back out, and try again in seconds, all without needing any special tools.

In this tutorial, you will learn:

• What a breadboard actually is and why it has that weird name.

• How the secret hidden connections work underneath the plastic.

• How the rows and columns are marked so you never plug a wire into the wrong spot.
