In the video where you add reading a voltage. The pot was connected to 3.3V but in the formule it was 5. Shouldn't be 3.3? The structure of lcd has several members. If you don't know the members for can to find out about them?
Hello, for make sure you can see a test in the screen. Then check my tutorials as I have so many tutorial of LCD with tempers, with voltage, with motor with servo and more . You will find something useful. Here is how to find a video in a channel th-cam.com/video/OhkUceBWcHs/w-d-xo.html
I got an error message that "no maching function for call to 'LiquidCrystal_I2C::begin.'" Really need help!!!!!! I have watched the video twice (already restart the IDE, installing the library, updating the address) but still cannot solve the problem
Read the error. It say call to undefined…. Which means library is missing and you have not installed it. Please watch fully. I don’t waste time. Everything I say is for learning
Yes if you don’t watch the video fully, this what happens. You can’t just type a test to display it. You have to know the length and put it accidentally
Why you clear the display everytime at the start of the loop? The whole display is blinking every 500 ms. This is not a nice way to display something. You have to clear only the charakters that change.For Example spaces if a value is less than.... Anyway, nice tutorial i enjoy it
@@robojax I came alright. The problem was too much libraries. I watch your videos thoroughly over and over again and I enjoy it. I've never been to coding or computer school all I know is what you taught me via youTube. Thanks.
LOL just check the date on the codes. these have been recorded on 2019. I am just publishing them not. Just adding the title "course" at the beginning and exporting them to mp4 for TH-cam. Over 100 lectures are waiting.
I can't get it to work. Keep getting this eerror: C:\4_Arduino\LCD2004\LCD1602\LCD1602.ino: In function 'void setup()': C:\4_Arduino\LCD2004\LCD1602\LCD1602.ino:48:12: error: no matching function for call to 'LiquidCrystal_I2C::begin()' lcd.begin(); ^ In file included from C:\4_Arduino\LCD2004\LCD1602\LCD1602.ino:1:0: c:\Users\debgreeno1\Documents\Arduino\libraries\LiquidCrystal_I2C-1.1.2/LiquidCrystal_I2C.h:58:8: note: candidate: void LiquidCrystal_I2C::begin(uint8_t, uint8_t, uint8_t) void begin(uint8_t cols, uint8_t rows, uint8_t charsize = LCD_5x8DOTS ); ^~~~~ c:\Users\debgreeno1\Documents\Arduino\libraries\LiquidCrystal_I2C-1.1.2/LiquidCrystal_I2C.h:58:8: note: candidate expects 3 arguments, 0 provided exit status 1 Compilation error: no matching function for call to 'LiquidCrystal_I2C::begin()'
Hi, clearly it say that "no matching function for call to 'LiquidCrystal_I2C::begin()'" so you have incorrectly installed the library. Please check it . Or follow this video th-cam.com/video/NXAswOc_2zg/w-d-xo.html
Very well explained, I understand how this type of display works now. Thank-you!
Thanksgiving👍

If you want to read 5v then connect it to 5V there is no problem with that. I had 3.3V pin available I used to without using a breadboard.
I have shown some more features of code on this video th-cam.com/video/NXAswOc_2zg/w-d-xo.html
please ,do a video how to coding a cnc drawing machine x,y and z axis moving.
Hello, i'm working on a little weather station, but i can't combine 2 codes in my arduino. Also the LCD screen doesn't light up. Can you help me?

Hey your code is working but the only problem is that only starting letters are appearing on the screen

Anyway, nice tutorial i enjoy it
this is introduction. Later when student learns how to write a function, he can clear specific character. Check my other videos.
Somebody help I am getting: no matching function for call to 'LiquidCrystal_I2C: : begin()' heeeeelp!.
you skip the video, this is what happens. please watch it fully.

So many new videos.... Do you ever sleep???!!!
