Lcd Arduino Wiring Diagram. We now supply a variable resistor potentiometer which replaces the resistor seen in diagram. 16 2 lcd with arduino wiring diagram.
Wiring diagram the above diagram shows how to connections are made between lcd arduino uno and bread board. A complete wiring diagram is shown below. Db7 is pin 14 on the lcd and it connects with an orange wire to arduino 12.
Once you have wired everything we can start programming the lcd.
We will be using the lcd in 4 bit mode this means you don t need to connect anything to d0 d3. The r w pin is connected to ground this will pull the pin low and set the lcd to write mode. Next are the remaining 3 data lines db6 pin 13 yellow db5 pin 12 green and db4 pin 11 blue which we connect to arduino 11 10 and 9. Connect 5v pin of arduino to ve rail of bread board.
