I have seen a video on Youtube about micro:bit. In that video I have seen two micro:bits on the left side of the simulator screen. How can you get two micro:bits at the same time?

I think it shows up if you use the radio, but if not you can find this project in the radio section of the example projects that should do it:

Hi @am.alonsogonzalez & welcome to the forum!

Two micro:bits appear and are used to simulate radio communication. A second one will appear if the radio blocks are run in the simulation. Here’s an example project — when “A” or “B” are clicked, a radio message will be sent and a second micro:bit will appear to recieve it: [https://makecode.microbit.org/S26589-78703-45329-37174](https://makecode.microbit.org/S26589-78703-45329-37174) .

The multi-editor can also be used to simulate multiple micro:bits and radio interaction: [https://makecode.microbit.org/---multi#](https://makecode.microbit.org/---multi#) . (The multi-editor can simulate two micro:bits that are running different programs, but that interact/exchange radio messages)
