Welcome to the Display-DHT11-DS1302-on-Atmega8 wiki!

Here is a video demonstration folks https://www.youtube.com/watch?v=mb-ydt5x38Q

Note that the RTC used is this https://www.fabtolab.com/DS1302-RTC-module I unsdertand the module thanks this tutorial on Assembler for mcu 8051 http://salvador.maciashernandez.com/Escolares/AstraZeneca/DS1302/DS1302.html

This project displays on a 16x2 screen time acquired from RTC module DS1302 and also temperature in celsious degrees and relative humidity sensed by DHT11, this last one uses 1 line for data transmit http://embedded-lab.com/blog/wp-content/uploads/2012/01/CombinedTiming.jpg Also DHT11 is very slow, needs an interval of 2 or 3 seconds per each reach in IDLE state.The method i used for reading the DHT11 was by polling, wich is not recomended by me. In next ocations i´ll use pin change interrupts.
