Lcd 4 Pin Wiring Diagram. A great solution to this problem involves the use of an lcd which is controlled over the i2c. Next you need to set up the contrast adjusting potentiometer.
The kimber wire helps bring it forward a little bit without being harsh. The enable pin on lcd will be connected to arduino 2 and the rs pin on lcd will be connected to arduino 1. The conlums and rows are indexed from 0.
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.
A great solution to this problem involves the use of an lcd which is controlled over the i2c. This pin is connected to 5v. Db7 is pin 14 on the lcd and it connects with an orange wire to arduino 12. Wiring diagram first connect the cobbler power pins to the breadboard power rail.
