The Tello drone has taken the world of drone enthusiasts by storm, offering an affordable and feature-rich drone experience. One of the most exciting aspects of the Tello drone is its ability to be programmed using Scratch, a popular block-based programming language developed by MIT. In this article, we’ll take you on a journey to explore the world of Tello drone programming with Scratch, covering the basics, tips, and tricks to get you started.
Getting Started with Tello and Scratch
Before we dive into the programming aspect, let’s cover the basics. To get started, you’ll need a few things:
- A Tello drone (obviously!)
- A computer or tablet with internet access
- The Tello app installed (available for both iOS and Android)
- Scratch software or online editor (we’ll cover this later)
Understanding Scratch
Scratch is a visual programming language developed by MIT specifically for kids and beginners. It uses blocks instead of text-based code, making it easy to understand and manipulate. Scratch is perfect for programming the Tello drone, as it allows users to create custom flight patterns, animations, and even games.
Setting Up Scratch with Tello
To program your Tello drone using Scratch, you’ll need to set up the Scratch environment on your computer or tablet. You can either:
- Download and install the Scratch software from the official MIT website
- Use the online Scratch editor, accessible through a web browser
Once you’ve set up Scratch, create a new project and download the Tello extension from the Scratch website. This extension allows you to connect your Tello drone to Scratch and start programming.
Programming Your Tello Drone with Scratch
Now that you have Scratch set up, it’s time to start programming your Tello drone! Let’s start with the basics.
Understanding Tello Blocks
In Scratch, you’ll work with blocks, which are color-coded and categorized into different sections. The Tello extension adds a new set of blocks specifically designed for the Tello drone. These blocks are divided into three categories:
- Motion: Control the drone’s movement, including taking off, landing, and flying
- Sensors: Access data from the drone’s sensors, such as altitude, speed, and orientation
- Actions: Perform actions like taking photos, recording video, and playing sounds
Creating a Simple Flight Pattern
Let’s create a simple flight pattern using Scratch and the Tello blocks. Follow these steps:
- Create a new project in Scratch and add the Tello extension.
- Drag and drop the “Take Off” block from the Motion category to the coding area.
- Add a “Fly Forward” block and set the distance to 10 meters.
- Add a “Turn Right” block and set the angle to 90 degrees.
- Repeat steps 3-4 to create a square flight pattern.
- Finally, add a “Land” block to land the drone safely.
Adding Sensors and Actions
Let’s take our flight pattern to the next level by incorporating sensors and actions. Follow these steps:
- Add a “Get Altitude” block from the Sensors category to retrieve the drone’s current altitude.
- Use a conditional statement (If-Then block) to check if the altitude is greater than 5 meters.
- If the condition is true, add a “Take Photo” block from the Actions category to take a photo.
- Add a “Play Sound” block to play a fun sound effect when the photo is taken.
Advanced Programming Techniques
As you become more comfortable with Scratch and the Tello blocks, you can explore advanced programming techniques, such as:
- Loops: Use loops to repeat actions or create complex flight patterns.
- Conditional Statements: Use If-Then blocks to make decisions based on sensor data or other conditions.
- Functions: Create reusable code blocks to simplify your programming.
Tips and Tricks for Tello Drone Programming with Scratch
As you continue to program your Tello drone with Scratch, here are some tips and tricks to keep in mind:
- Practice makes perfect: Don’t be discouraged if your code doesn’t work as expected initially. Practice and experiment with different blocks and techniques.
- Use the Tello app: The Tello app provides a live view of your drone’s flight, allowing you to troubleshoot and refine your code.
- Join the Scratch community: Share your projects and learn from others in the Scratch community.
- Experiment with sensors: The Tello drone comes equipped with a range of sensors, including a barometer, accelerometer, and gyroscope. Experiment with different sensor blocks to create unique projects.
Conclusion
Programming your Tello drone with Scratch is an exciting way to explore the world of drone programming. With Scratch’s block-based language and the Tello extension, you can create custom flight patterns, animations, and even games. By following this guide, you’ll be well on your way to becoming a Tello drone programming expert. Remember to practice, experiment, and join the Scratch community to take your programming skills to new heights!
