Synchronizing 80 ESP devices in a carnival parade is definitely a challenge, but it’s possible with some planning. Here are a few approaches you could consider: ### 1. **Wi-Fi Mesh Networking** - **ESP-MESH** : You could set up a mesh network using ESP-MESH, which allows multiple ESP32 devices to communicate with each other over Wi-Fi. This would enable your devices to relay messages between one another, extending the range and reliability of the network. - **Pros** : Scalable and can cover larger areas. - **Cons** : Might require more setup and configuration to manage the mesh. ### 2. **ART-NET or sACN** - **ART-NET** : This protocol is designed for lighting control and can work over Wi-Fi. You could set one ESP32 as a master controller and the others as slaves. This way, you can send commands from the master to synchronize the lights. - **sACN** : Similar to ART-NET, sACN is another protocol that supports DMX over Ethernet. - **Pros** : Well-supported in lighting applications and can handle multiple devices. - **Cons** : May require additional libraries and setup. ### 3. **Bluetooth or BLE** - If you’re looking for a more localized solution, you could explore Bluetooth Low Energy (BLE). Some ESP32 libraries support BLE mesh networking, allowing devices to communicate without Wi-Fi. - **Pros** : Good for short distances and avoids Wi-Fi interference. - **Cons** : Limited range compared to Wi-Fi. ### 4. **Broadcasting Synchronization Commands** - You could use a single device to broadcast synchronization commands (like color changes or effects) to all others using UDP or multicast messages. This approach doesn’t require a mesh but can be effective if the devices are within range of the broadcast. - **Pros** : Simple to implement. - **Cons** : Range limitations and potential packet loss. ### Implementation Steps 1. **Choose a Communication Protocol** : Decide which of the above methods fits your needs best. 2. **Set Up One Master Controller** : This device will send out synchronization commands to the others. 3. **Test in Small Groups** : Before the event, test with a smaller number of devices to ensure synchronization works. 4. **Deploy and Test in the Field** : On the day of the parade, set up your devices and do a final test to ensure everything works as expected. ### Additional Considerations - **Power Supply** : Ensure that all devices have a reliable power supply, as long parade durations may drain batteries quickly. - **Signal Interference** : Consider potential interference from other devices in a carnival setting, especially if using Wi-Fi.
