LCD 16x2 don't works with Arduino UNO in Flowcode 7

Post by silicioslab »

Hello, I'm developing a menu using an Arduino and a 16x2 LCD, but when I write the code on the Arduino, to show on the LCD, the values do not appear.

What should I do to solve the problem?

This is my flowchart and a image of the project.

Hello,

It could be the length of your wires causing the problem. Can you plug the LCD directly into the breadboard?

Does adjusting the contrast potentiometer help at all?

Looking at the picture you sent have you wired up the data bus as shown here. e.g. using the top nibble D4 - D7.
