hello,

I have constructed your circuit in proteus 8 and also constructed on the bread board output on both are same
1st it says set time we are able to set time
then it displays the time that we have set and seconds digits are stuck to 00 they dont procedue
cant set alarm it also do not display the temperature
provide me with ur direct contact details

[indrajeet Tmabe]

this is circuit and code used from ur website

code copied to keil and then burned as a hex file still not working tell me what is the probleme
