    working with a 5v I2C device on a 3.3v I2C bus can either destroy the device immediately... reduce its lifetime. So, you can safely run 3.3v devices alongside 5v devices on the same bus With a Bi-directional Voltage Logic Level Shifter 4 Ch I2C 5v to 3v3.

    The Logic Level Shifter 4 Ch I2C 5v to 3v3 is designed to with printed pins name on the board to help you identify which pins do what. There are twelve pins total – six on each side.

    Logic Level Shifter 4 Channels 5v to 3v3


    The middle section of the board is the power section, from one side there is the 5v and the other is the 3.3v should go. working with this board required powering all the middle section. If you’re converting 3.3V to 5V (and vice-versa), for example, have to connect the 5V with the “HV” side, and 3.3V with the “LV” input. don't forget the ground!


    The outer pins related to inputs and outputs for channels 1 and 2. Each channel has one voltage divider and one MOSFET shifter.
    The labels on these pins – “RXI”, “RXO”, “TXI”, and “TXO” – help you connect your device as follows:

    • RXI – 5v input to a voltage divider from the 5v devices. Signal will be shifted down to a 3.3 on the “RXO” pin.
    • RXO – this is where the 5v input signal shifted to with 3.3v this is the Output of the RXI.
    • TXI – here if have 3.3v signal you want to shift it to 5v like you want to connect the I2C from the raspberry pi to the Arduino normally the Arduino can read signals of 3.3v but this way will assure the reading.
    • TXO – here is the output of the TXI that will give you a 5v signal from 3.3v signal on the other side.

    To send a signal from the low-voltage side to the high-voltage side (e.g. from 3.3V to 5V), the signal must be input at “TXI”. It’ll pass through the converter and come out as a higher voltage on the “TXO” (transmit output) pin.
    On the other hand, a signal that strictly travels from high to low-voltage should pass from “RXI” to “RXO”.
    Sending a signal from the high side to the low side is less restricted. We can use either the bi-directional channel or the voltage divider, but we may need to leave the bi-directional channel for converting from low-to-high.

    Example connecting the Arduino and Logic Level Shifter 4 Channels 5v to 3v3 with HC05:

    as you see in the next schematic we have connected one of the low voltage sides of the voltage level to the HC05 with that we protect the Bluetooth module from being destroyed on the long run and we connected the opposite high voltage side from the converter to the Arduino with that the Arduino gets and gives 5v signals and the Bluetooth module takes and gives 3.3v signals without worrying from and risk on the module and good voltage levels on the Arduino 

    Here, we will transmit data from smartphones via Bluetooth to the Arduino Uno and display it on the Serial Monitor of PC.

    Data is sent from the Smartphone using the Bluetooth terminal application.

    void setup() {
      Serial.begin(9600);	/* Define baud rate for serial communication */
    }
    
    void loop() {
      
        if (Serial.available())	/* If data is available on serial port */
    { Serial.write(Serial.read()); /* Print character received on to the serial monitor */
    } }
