1) Using your Arduino UNO, write a program that makes your LED flash at a user set frequency. Your code should ask the user to enter a frequency. Show that frequency on the monitor and make the LED flash at that frequency The user should be allowed to change the selected frequency while program is working. 2)This assignment builds on the (1). In this assignment, I need you to ask the user for two quantities. Frequency and Duration. (in Hz and Seconds). Your LED should then flash at the requested frequency for the given duration. An entry of 2 and 10 for example, should make the LED flash twice per second for 10 seconds. The user should be able to enter new values when first is done.

For question 1, i'm a bit stuck between serif fonts or large enough type to read. serif fonts are good fonts to use because their easy to read. but you also need your type be large enough to read. if i had to say what you need to consider most important, i would say d is the answer.  for question 3, i believe the answer is d. it seems most appropriate to do that. on every page or every other page would be too much, and only on the contact page just seems inappropriate.  for question 4, it's probably a. by "color scheme" it doesn't mean just one color, but a set of colors. colors that are complimentary to each other. having too many is too distracting so it's best to limit it as much as possible, but not to the point where your website looks dull.hope this !
