Raspberry_PI_01_Level_Shifter_Circuit

• Hardware Connection between Raspberry PI and Arduino Uno level Shifter circuit for Serial Port UART interfacing with each other.

• TX pin second last from Arduino GPIO is connected with 1.6K ohm resister and resistor is connected with RX pin of raspberry pi at pin number 5, again, this pin 5 is connected with Ground GND using 3.3kOhmResistor as shown.

•  RX pin from Arduino board is directly connected with TX pin of Raspberry PI,there is no need to do voltage level shifting.
