Build the suitable circuit and write the code to build the following: - Connect 4 LEDs and a Button to the Arduino board
- Build a sequence of steps, each step on a button press

First step in sequence:
The 4 LEDs will fade-in from 0 to 255

Second step:
The 4 LEDs will fade-out from 255 to 0

3rd Step:
LED1 and LED3 will light up. (LED2 and LED4 remain OFF)

4th Step:
LED2 and LED4 will light up. (LED1 and LED3 with shutoff)

5th Step:
All LEDs will light up.

6th Step:
The LEDs will shut off one after another, by duration of 500 ms

Explain why it is reasonable to assume that receiving 3 duplicate acks in tcp is an indication that the network is not currently congested.

1. technician a says horsepower information can be used by consumers to compare the power of different automobile engines. technician b says that manufacturers will often list the horsepower output of their engines in the online service information. who is right?

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. the highest speed measured was 78.1 mbps. the complete list of 50 data speeds has a mean of x overbarequals16.11 mbps and a standard deviation of sequals18.65 mbps. a. what is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. how many standard deviations is that [the difference found in part (a)]? c. convert the carrier's highest data speed to a z score. d. if we consider data speeds that convert to z scores between minus2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant? a. the difference is nothing mbps.
