do i need an arduino for a rf frequency?
September 16, 2019 - 12:39am

So i want to make a simple circuit that would have 2 devices that are linked and when one of the leds turn on the other devices led would also turn on, potentially making it more sophisticated in the future but im struggling to get my head around how i need to be doing it. any suggestions please??

You can use RF modules for wireless communication

I assume that the link you are refering here is a wireless link. In that case you need some type of wireless communication between two microcontrollers. In these cases RF would be a good choice. You have lot of options here like 433Mhz RF, NRF24l01, LoRa, etc... If you want a decent range and payload you can try the NRF24L01 module
