Lesson 22 - 1602A LCD Module

[@maaliatat8428]

These videos are very helpful and I am very lucky to have found such a hidden gem on youtube. Thank you for all of the hard work that you put into these lessons. You've helped so much!

you probably dont care but if you guys are stoned like me during the covid times you can watch all of the new movies and series on Instaflixxer. Been binge watching with my brother for the last days xD

@Easton Oakley Definitely, I've been using instaflixxer for since november myself :D

I am so glad I found this channel! Sometimes when reading the instructions given it can be confusing, but you explain it so well!

Thanks!

Very well done, and i like the 2-part approach using the native parallel interface and then moving to the serial I2C. Your notes, code change explanations, and links are leagues ahead of many others. Thanks for just the tips i needed before updating a prototype that i have an LCD and arduino embedded in.

Hi,I started you watching on summer for arruino lessons since I bought mega2560 kit.Then I left arduino and now I have started again. This videos are very helpful

I hate Fritzing's forced donation. At that point in time it is payware. However it can be built for free if you grab their source code from Git. I don't mind donating for decent freeware but a "Forced Donation", nope. And thanks for your taking the time to make these videos and upgrades how you do. I have found them very helpful.

Thanks for your tutorials sir very helpful

Ricardo, thank you for the great course!! Please suggest software for arduino and schematics simulation.

[@sonogylabsonogylab2262]

I dont see the link you spoke of to the software /sketch that returns the HEX address of the I2C module. Can you point me to it or, of you forgot, add it below? TIA

I had to fill in the args for lcd.begin() -- with the columns and rows of the display (16, 2) -- instead of leaving it blank, AND I needed to write Wire.begin() into the setup func or else it wouldn't run.

[@studentcarloslorenzozuniga3914]

Could you make a video for basic coding?

[@tahevol]

I like your videos

thanks

sir, i only got white boxes in the 1st row and it wont print a word, any solution ?

[@rickmorenojr]

Check all your LCD wiring. Contrast is the next thing to check. Make sure that V0 is properly connected to the variable part of the potentiometer, and that the potentiometer is connected between the +5V and ground.

[@adfflame7845]

@@rickmorenojr i checked otut already i also adjust the contrast from 0 to 100 but no word showed up

[@matchafluff]

im having this same problem right now, did you ever figure it out?
