You must ensure that all answers are ( 100% correct ) by solving each problem in at least two different ways which give the same result.Both ways must be stated ; but you only need to produce your answer to only one of your methods.All questions must be answered on ( Excel ) , ( On the same Excel file that I've attached).You must explain all answers step by step in understandable manner ; and you must add Comments for each answer explaining what is going on in each step.
I need a unit that will enable me to control a 4 digit 7 segment led display to read a set number imputed by user this setting would need to be retained when powered off and then back on. even though I have stated a 4 digit 7 segment led display. If you could advise on another product i would be open to ideas this unit needs to be small as possible. I would need to know how much time this would take and a cost for the prototype this could lead to a mass production requirement
