@ anshul: “output is not coming”. where exactly you got struct… what exactly happens when switch ON the ckt….

[dagakshay]

@ Pankaj: Initialize your LCD properly.. this happens only when you initailze your LCd in some other mode….

helooo Mr…..

1st do it in bread board……

this project proper….v did sucesfully……

[Qaisar]

 

dig_ctrl_var = vote_amt[p]+48;  ?



lcd display ascii character.

48 = 0 in ascii

how u will display 5 on lcd?

 

simple

add 5 in 48 =53

53 decimal charatcer is equal to 5 in ascii characters.

have a look on ascii table . just google it ..

 

the above statemnt is taking a number from a array , converting that number to ascii and copy to  dig_ctr_var.
