I don't understand what specific problem is the first tutorial, my screen is shining too bright and won't even showing boxes, so what I need is to adjust using potentiometer right?
If you have Error 4 and you connections are OK, make sure your LCD is getting power from the Arduino or they both have shared power source. Arduino must set this pin HIGH in order to write.
Hey there! My LCD just shows black boxes irrespective of what command I try. I checked my enable pin and it's connected to Vcc properly. The issue is persistent.
Buy i2c module. Connect with i2C. I2c required only 4 wire connection. This will work perfectly to connect all the 12 wires, potetio meter. Then only it will work. If any one of the wire loose connections it won't work.
Hi everyone, mi problem is the following: I have my 16x2 in my arduino uno. I have a script to appear some text and it is ok, work it without problems. But my proyect is more than that, with the same script i add it more to use a DHT22 (Temperature and humidity), DS3231 (RTC for time), and micro SD card (save the data). When i put these modules, my LCD turn crazy, appear in all the display just the numer "3" yes, in the all spaces 16x2. and another case appear letter "f". Is strange bcs in the serial monitor the all dates is ok, work withouth problems. I dont know why. Has this happened to anyone?? any advice?
Hello and Thank you very much very good solution, but I worriy about problem occur during the program is running if we reset board the process will also restart that cause me very big problem now I still can't find the solution yet.
@@TeachMeSomething just today sir, I found my jumper cable is not fit to both LCD I2C pins and Arduino UNO then I build up the new cable with soldering pin both side the problem disappeared lol because your video, Thank you very very much 🙏🙏🙏🙏🙏👍👍👍👍👍👍👍👍👍👍
Hi my lcd is showing random values after sometime ..need to reset the power supply of whole circuit then works for sometime and again ...same problem ..plz help
@@TeachMeSomething bro as you shown above error number4. I have make changes in my circuit and do like what you do. But my 1602a display only showing first line. Last time when i use my 16/2 display my potentiometer burnt out . Is my display get shorts circuted
@@gs_gamings My tips Solder pins properly. Avoid loose connection in rs, en, r/w pin First line working properly means check your program. Did you give program for second line or you have given empty.
Thank you so much bro! My LCD was in Error 3, before watching this i almost threw it away thought it was short-circuit!
🙏🙏🙏

I got a old LCD SCREEN.
But now is flashing all the time. The information doesn’t appear in the background. Did you know how I can fix it ?

@@TeachMeSomething Is it mandatory to have an I2C?

Please can you help
Connect the sda , scl pin properly
Yes
Thanks,
I was putting them on A4, A5 but problem solved when I shift them to dedicated sda,scl pins.project is on Arduino 2650.
What do you mean by enable pin?
All data will take place when en pin gets 1

1. Because of loose connection
2. Or u didn't give clear comment in your program to display next texts.

mine works but the error 3 i tried is not working the data pin are good but it display ?0?
Wire loose connection issue
Khali light hori h yr kuch btao potentiometer lgana hoga???
The Enable Pin reconnection didn't work please help
Try to use i2c board lcd.
It is waste of time
@@TeachMeSomething is that the best option? Damn I'll have to remake the entire circuit board 😭💀
ur trimpot without resistor bro??
No. I have soldered connecting pins.
To change pin order 1 2 3 to 1 3 2. Because to insert in breadboard easily.
@@TeachMeSomething can i use 103 trimpot..bro?
Yes
103 trimpot will work
@@TeachMeSomething I mean, 103 or 205 but without resistor? it's needed to adjust 1602 IMAX..🙏
