Hi,
I have tested the LCD and BME seperatly , all working fine checked address LCD 27, BME 76
when I complie with this line in I get an error, If I omit the line with // , compiles fine and uploads.
But nothing happends on the LCD.
Any ideas. Thanks again.
lcd.begin();
no matching function for call to 'LiquidCrystal_I2C::begin()'

Hi! Great tutorial! But where is the code for 2004 LCD ? Thank you!

[@robojax]

Hi, all videos have description area and the link is there

[@BPEMETO]

@@robojax It says "There is separate code for LCD2004" ... I could not find it.

[@gauravdighe8474]

hii sir after watching all videos .I decide to make interface MAX30102 and MLX90614 sensor with LCD display but i got problem with connect SDA and SCL pins of sensor and lcd together . I humble request u sir can u make video on it please sir please. i waiting for the video thank u.

This is spam

[@pic__l_]

where is the code for LCD 20x4 ?

[@robojax]

it seems you did not watch the video. LCD1602 or 2004 is is the same. you just set it in the code. This is lesson 30. Introduction to LCD is separate video, the link is in the description. please watch it. All links are in the description for the code and related videos.

NO ESTA EL CODIGO
THERA ISN´T THE CODE.. Y GRACIAS

[@robojax]

Gracias por hacérmelo saber. Hace dos días agregué la conferencia 103 y ese código creó este problema. Ahora está funcionando.

[@robojax]

Did you check it?

HI
When compiling your sketch I getting this message. ay ideas what I can do to fix it . Mike

It seems you have skipped lesson 19. And introduction to the temperature sensor. Once both work them come to this lesson

[@1mikechung]

Hi . Thanks for reply. I will recap on the lesson. The sketch I complied is from this video, so not sure why it doesn’t work. I have used you other examples controlling motors etc, really good. Do you have any building Segway’s?

[@robojax]

you have skipped. without libray it won't work. so watch and install the library from lesson 19. I just watched the video and right at the begning is mentioned that you must watch 1-Introdcuction to LCD, 2-Introduction to BMP280.

[@1mikechung]

Thanks for your reply and so prompt. Your other videos are so informative and I have used your examples to learn so much.

[@1mikechung]

Found the answer , I left the first line without // . Will retry tomorrow. Thanks
