Quarky Connect

The Quarky Connect extension allows multiple Quarky devices to communicate wirelessly using ESP-NOW. With this extension, one Quarky can control others, send commands, or coordinate actions, all without needing a Wi-Fi router or internet connection.

This feature opens up endless possibilities for creative and interactive projects. Whether it’s controlling a swarm of robots or making them work in sync, Quarky Connect is perfect for classroom activities and fun challenges that involve multiple robots.

Create Exciting Projects with Quarky Connect!

With Quarky Connect, you can create innovative and exciting projects like:

1. Go Kart: Control multiple Quarky robots in a race to the finish line, where each robot needs to avoid obstacles and follow specific paths.
   
2. Pac-Man: Create a multiplayer version of Pac-Man where Quarky robots can act as the ghosts, chasing the main character in a dynamic maze.
   
3. Fruit Chase: Program Quarky robots to chase and collect virtual fruits on a grid, with each robot moving based on the commands sent by the master robot.
   
4. Rangoli: Use a fleet of Quarky robots to collaborate on creating intricate Rangoli patterns, where each robot fills in a section of the design simultaneously.

Master Quarky

• Acts as the central controller in a Quarky Connect setup.
• Sends commands to multiple Peer Quarkys to control actions such as movement, display changes, and more.
• Operates in both Stage Mode and Upload Mode.
• Communicates wirelessly with Peer Quarkys using the ESP-NOW protocol, without requiring a Wi-Fi router or internet connection.

Peer Quarky

• Listens for commands from the Master Quarky.
• Executes the specified actions.
• Works only in Upload Mode.
• Requires specific code to be uploaded to enable communication with the Master Quarky.

Stage Mode and Upload Mode

• Stage Mode enables you to control multiple Quarky devices wirelessly and interactively in real-time. It is ideal for applications like gaming, where you need immediate feedback from your actions.
• Toggle between modes using the button in the top right corner of PictoBlox.
• Upload Mode is ideal for making autonomous robots or devices that do not need to stay connected to the computer. After uploading the code, Quarky runs the program autonomously.
• Upload the code and switch to Upload Mode for projects that need to work offline.
