ESP32-DevKitC VIE and Arduino UNO Serial Communication

Other Hardware 3rd Party Boards

hey,
i saw some videos on YT,
communicating with the esp32 board and arduino uno
using UART communication.
and also i saw some forums saying u shouldn't do that cuz esp32 works on 3V and arduino works on 5V.
please lemme know how should i do that,
can i just directly hook, TX to RX, RX to TX and live a happy day?
or does it have any long term effects on the boards?

That's why you use a logic level shifter if you want a esp32 board and arduino uno to communicate
