Problem with PIC16F877A

[Antonio]

Hi my friends,

I’m Antonio, and I’m beginner with microcontrollers. I want to automatize my terrarium with PIC16F877A.

 

For this project I’m using:

1) LCD Hitachi hd44780

2) DHT11 sensor humidity & temperature

3) 2 relay for humidifier and heater

and any button to choose in the menu.

 

I’m looking for a library to DHT11, but I don’t find anything.

I don’t know how to make a library, do you have this file?

And do you have any sites where I can download the libraries?

 

PS: Can you give me some advice how I can to use the LCD?

 

Regards.

Hi,

 

The sensor which you are using is anlog sensor. It will give you analog output on its pin. You give this output to analog input pin f controller and write ADC routine to read that value.

 

For LCD, you can display temperature and humidity on screen. Go through the various sections of this site ans you will find lots of tutorial to answer your all queries..
