Connecting App inventor with Microbit and NFC

We are creating a product, controlled by an app. It’s a lamp for kids, for telling stories. When you read a tag (NFC) several effects start at the same time: led light, sound and fiber light.
From a software point of view, we are struggling with communicating the signal from App inventor to the Microbit because some of the components are not using Bluetooth (like the neopixel light) and so we might need to add one more microbit in the middle to send the signal from the 1st one, connected analogically.
Please can you give me advice on how to communicate to the microbit from app inventor how to transfer into to the 2nd one?

It may not be the answer you are looking for, but I would be grateful if the following articles on my blog could be helpful:
