Design a controller to display an electronic nine-dotted die as shown below. A set of these could be used to display decimal numbers and some mathematical equations. The inputs to the controller represent a 4-bit number, W, X, Y, Z, which indicates what is to be displayed. There are nine outputs, A, B, C, D, E, F, G, H, J, one for each of the dots. It requires 1 to light the display. The diagram below shows each of the inputs and the display that results. A black dot indicates that the bit is lit; a circle indicates not lit. Note that 0 lights none of the lights; 9 lights all of them. 0101 1010 0001 0110 1011 1100 0010 011 decimal poine 011 1000 1101 Other combinations 0100 1001 (1110, 1111) wil nover occur.

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?

I have an O Gauge track and would like to convert it into a “sensored” track. Additionally, I would like to connect that track to an ESP-WROOM-32 board that should flash an LED whenever the track detects a non-moving train. Please list all the components (and how many of each) needed. Also, what’s the procedure for connecting the components?
