Using a logic level converter
As you all know regular Arduino boards work on a 5 volts logic level.
But there are development boards such as the esp8266 , nodemcu , some Arduino boards and other development boards that need at most 3.3 volts or else you will damage them.
Sometimes you also need to connect 3/3 sensors and devices to 5 volts pins.
That is when a logic level convertor is needed.
The logic level converter is bidirectional.
Meaning that if a signal of logic 1 at the level of 5 volts enters on the high voltage side.
Than a logic 1 will exit on the low voltage level side.
