Yes i am making a web server to control traffic lights and adjust the timings . i wanted to have a block on the page which will be showing the count down timer . i managed to make that but the real problem is to update that time every second without refreshing the whole page. m new on the web stuff and not sure that client.read() will read the data from webpage that i will make from dream viewer and save it on sd card as making an interactive webpage by using the client.pritnln() takes lots of RAM and is very hectic .
