when I try to import DHTLib.zip in my Arduino Create I get this message:

Libraries that could not be imported:
[] [Lb+T/b/m] 400 invalid_request: attribute “name” of response is missing and required, attribute: name, parent: response

Any ideas why?

On some LCDs the pins are arranged differently. If that doesn’t work, it could be that the screen contrast is set too low…

Not all LCDs have the same pin out. Check the datasheet for yours, or see if the pins are labeled on the PCB. I’ll update the diagram in the post so you can see the pin labels

This topic was discussed in Arduino forums. Specifically the forum post, in 2012, talked about how lcd.print() and lcd.write() functions are different. In fact, without going into too much detail, the print function evetually calls the write function.

It’s nice for the hobbyist to tinker. It allows the learning process to grow. So, while I was reading the post, participants replied with differing ideas. One poster tried making the characters move in animation. Copying and pasting the code, I believe the poster was having trouble with developing the animation. As it turns out I discovered where he was having the problem. In the loop section of the code the poster didn’t clear the screen to print, or write, the other characters.

The following is the fix to have animated characters on the lcd.

#include

// initialize the library
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

You can either change the baud rate of your serial monitor, or you can change the code. In the setup section you can add Serial.begin(9600), or what ever baud rate you want to use. Hope that helps

I am quite new to this,never used LCD and arduino before.
I want that one text should be displayed on LCD when I send ‘1’ as serial data to arduino and display some other text if I send ‘2’ as serial data.But when I put Serial.begin(),some strange characters are displayed on LCD.I know the problem is with Serial.begin.
I tried it,but it displays both texts simultaneously .
I would be extremely thankful if I can get some useful suggestions to solve my problem.
Thanks in advance!
