Hi, How you are all? I need a help from you,I want to know that how can I interface seven segment display with any timing circuit? Which can display a time of few seconds. Plz provide any related document or schematic diagram. Thanks.
briefly speaking, first u have to make that timing ciruit,
then u have to choose which 7 segment u will choose ... common cathode or common anode.
then u can check which one led will turn on my cheking its data sheet.
well if u r totally new in electronics then it would b difficult to make it urself, u should consult som document. let me search
as much as i agree microcontroller is the simpler way out i suggest you make it by means of a flipflop design with the 555 timer acting as the clock for transition, synchronus circuit will be more than enough then taking the output on to the 7 segment.
first of all do you know how to check for the segments sequence? like determine which pin belongs to which segment and weather the 7 segment is common cathode or common anode?
let me know and i will be posting a circuit for you soon
to connect 7 segment display with timing circuit we need decoder driver for 7 segment,it's ic # may be 74154 or some what,for 555 timer to connect with 7 seg 1st we've o put counter which can get clock from 555 then use that same technique
