[@handletodizmantle]

thanks dude works perfectly and is my first try as a noob

[@nikajobava481]

I think it would be good to do one about rotary encoder and one about I2C 0.96 inch lcd

[@sadatiqbalpriom7389]

I am using D1 Robot 1602A LCD shield.. I counldn't find the V0 pin :(

[@kaito-ww1yd]

wow, this channel gave me act like a horse !

[@isomer805]

can you once give the me the exact link of the code.Actually i was bit confused of the above one given in the description box

[@Science.Buddies]

Hi - the code we're using in this video is identical to the code from the links in the description.

[@topquark22]

The module I got has 4 wires sticking out the left-hand side of the board. What is that for?

[@Science.Buddies]

We can't say for sure, you would need to check the datasheet or instructions for the module you bought.

[@topquark22]

To answer my own question: Turns out the one I got is I2C. It is so much easier and uses fewer wires!

[@topquark22]

In the tutorial it says that the device uses SPI, and uses the MISO and MOSI pins (12, 11) but I don't think this is accurate. The device does not use SPI and you don't need to use pin 11 for Chip Select. In fact I can't do that, because I have other devices on the SPI bus! I think this part of the Arduino Tutorial page needs to be corrected, as well as the example circuit.

To clarify - you're talking about the Arduino website and not our tutorial, right? If so, you'd need to submit this comment to them directly; we aren't officially affiliated with Arduino.

[@chese1976]

what kind of resistor is it

[@chese1976]

nvm

[@m.ramadevikrishnaprasad7771]

Can we plug the LCD on to the bread board

[@Science.Buddies]

Yes, if it has header pins you can plug the LCD screen directly into the breadboard.
