REQUIREMENT

1.RELAY

2.ARDUINO PRO mini,or ARDUINO UNO

3.LCD DISPLAY 16x2

4.RTC REAL TIME CLOCK DS1307

5.12v ADAPTER

6. LM7805 5v regulator

7. FTDI232 FOR upload arduino file

Step 1:

MAKE 12v to 5v DC STEP DOWN

Step 2:

MAKE RELAY CIRCUIT AND DISPLAY CIRCUIT FOR ARDUINO

Step 3:

//CODE SET TIME SWITCH ACCORDING REQUIREMENT

<p>thanks to the help :-)</p>
<p>Nice and very useful!! Thanks for sharing!</p>
Impossible d'acc&egrave;der aux r&egrave;glages de la date et de l'heure j'ai essay&eacute; plusieurs solutions mais sans r&eacute;sultat
<p>Great controller design</p>
<p>thanks. ?</p>
