i just have to try if it is possible if i connect my 7-segment led display with my 555 timer without any using a microcontroller or the use of a program. im trying to make a simple project that counts events using those components. i just need your advice sir if this idea would be possible.yhank you sir ajay!

hi jusal,
u can use the 555 timer clock to pulse a bcd counter like 4518/4520 whose bcd output can be given to a bcd to 7 segment decoder like 4511/4543. check out the datasheet of the mentioned ICs to get a design idea.
good luck.

hi jusal,

yes, you can use 555 as pdi suggested also you can cascade above decoder ICs to count more than decade.

Hi Uttam,

Can u brief the details of your project.;)
As the Remote control you can make use of Phillips TV Remote available in the market which works on RC5 Protocol.
and on the Receiver side you can make use of IR Receiver TSOP 1736/38 and need to write the RC5 decoding algorithem

.:bye
