mas.s60 problem set #3 due 10.3.12 Readings: Arduino references: http://arduino.cc/en/Reference/HomePage Horowitz and Hill: skim ch. 8, 9.01 through 9.09. if you have time, start skimming chapters 10 and 11, these will be assigned next class. Scherz: skim ch. 12, pay particular attention to 12.13. feel free to take your time, as these are the same readings for next class. problem 1: write a program for your arduino that takes in a string of alphabetical characters from the terminal monitor, and reverses the capitalization on them. for example, "A" becoms "a", and "b" becomes "B". have this new character printed to the terminal monitor. print up a hard copy of the program to turn in, in class. problem 2: connect an LED and resistor to your arduino, so you can control the brightness of the LED. make the LED slowly fade in and out, like a heartbeat. leave this program on your arduino, and bring your arduino to class, so we can see it working. also print up a hardcopy to turn in, in class.
