Hello, I would like to ask if there are Arduinos that has a built in transmitter and receiver signal to be used for our project. If not can I wirelessly connect two Arduino Lilypad to have a transmitter and receiver signal. Also, if I could not pair two Arduino Lilypad what can I pair with an Arduino Lilypad. I would appreciate if someone whould reply because I'm really not particular with these stuff since I'm just a Junior Highschool. Thank you : )
One transmits only, one receives only? Yes, you can add simple 433 MHz modules to do that.
Both need to send and receive? Both can add nrf24L01 module to talk back & forth.
I just bought a pair to play with.
There are Arduinos with built in wifi.
A couple of ESP32's using ESP-NOW would be a simple solution for short range communication
What sort of range do you need ?
