I want the letters arranged using red,green and blue leds for each letter.
When first letter blinks red the second shud be blue ,third green,fourth combination of red and blue....so on.....at a single time.After a delay again the process shud start wuth the first letter with a different colour and so on..
please some one inform as to which led swith rating shud be used for a good brightness..
I want to do it with PIC microcontroller 16f877
I have doubts regarding driving the output from a single pic o/p to lit a no: of leds for ex...about 400 leds from a single o/p.....
is it possible....?
what drivers shud i use ...?
Suppose I am using a dmux to get the required combination of outputs...according to the inputs from pic den
how shud i drive a single o/p from dmux to lit about 400 -500 leds.from a single channel.
please some one help if you have understood my problem.....as I am a beginner to this..
