I wish to do a project which would multiplex 16 displays for a digital clock with date,day,month,temperature and time in hour and minutes.I was successful in a similar project using 16 x 2 LCD display and atmega328 micro controller. I have done search on internet and is acquainted(somewhat?!) with the basics of charlieplexing, multiplexing and 4 to 16 decoder. I have references which give circuits for a digital clock using fewer 7 segment displays. I have removed the requirement of display of seconds from this project to bring down the requirement to using 16 displays(not all of them 7 segment). I aware of the requirements of pin currents and total current for a micro controller. If these requirements are met for each of sixteen display that would be in the project, my level of knowledge fail to see any other difficulty that I WILL encounter in the project. Any suggestion/comment, from too ambitious/foolish to a helpful to undertake the project?
