Final Exam 2012

Note: Please do not handwritten.

I have a wooden toy train that runs on wooden tracks. I would like to place two ESP-WROOM-32 Boards on top of the train. Broadcast communication (which involves radio frequency, not Wi-Fi) would help communicate about the train's lateness to five other wooden trains on the same track. Local communication would help communicate to the train station about the train's lateness. I would also need radio frequency Tx-Rx Modules for discharging and undergoing the signal, and repeaters just in case the signal loses power due to long-distance traveling. My wooden train should be automated. It should run at 4 inches per second, keep a minimum distance of 30 seconds away from the other wooden trains, and make a 17-second-long stop every 500 seconds. What's the procedure to connect the components? What's the Arduino code (C++) for this project?

A person is recording measurements from an analog data reader. During the first reading, he was not looking at the meter from a straight angle. He gets the reading of 72. At a second reading later he looks straight at the machine and gets the reading of 70. a) Which reading number is nearer to the actual value? What is the error type that happened in that reading? b) c) Suppose the data reader becomes faulty due to the extreme heat and gives a third measurement of 65. What type of error happened now? The data reader is working properly now, but there is a slight difference between two readings for the same measure. What type of error happened now and how can we d) minimize it?
