Is there a way I can show a message from a node on a display?

[image] luis: Im talking about a LCD display Do a search of installable contribs... might be one that does what you want. Also try I2C (if your display supports that) or OLED if you have that type. [image]

What sort of display? Do you mean in a browser? If so then if you are using the node red dashboard you can use the notification node.

Im talking about a LCD display, and I wanted it to show some messanges. Im doing it in a Raspberry pi

Its a normal 16x2 lcd (ds1602a) and I need it for a project in school, I also dont have a 12C module, is there a way i can program It without the 12C ?

I think it may be similar to an HD44780 style connection - If so then the older node-red-node-pilcd (node) - Node-RED node may work.

Yes Its exactly like that, I'll try it, thanks alot for the help.

I tried a simple node but Its giving me an error of "Command not running" [image] [image]

Did you see this on the node's flow page Requires the RPi.GPIO python library version 0.5.8 (or better) in order to work. Do you have it installed?

i bought a lcd with an ic2 module, is there any node that I can work with for it ?

see this recent thread [image] Trying to send text to LCD over i2c contrib General Good on you. Glad it all works.
