Q1) Write a sketch in IDE for an ultrasonic reversing sensor mounted on a mobile robot driven by two stepper motors. The system will turn the stepper motors off whenever the distance read by the ultrasonic is less than 5 cm. Q2) Write a sketch in IDE that uses ultrasonic sensors to detect the presence of people inside the chamber before spraying alcohol. The chamber uses two ultrasonic sensors, as people has variable height, and a pump operated through relay. The task required that both sensors should be activated before operating the motor for 5 seconds spraying. Q3) Due to coronavirus, the number of people inside stores should be limited to a certain number. Write a sketch in IDE that uses two ultrasonic sensors to calculate the number people inside the store and present a message on the entrance door (use serial monitor here instead) if the number of people exceed a predefined threshold. The store has a separate entrance and exit doors.

Lesson: Application of Computer Graphics Given an orthographic camera with direction d, up u, and center c properties (size is fixed to 1), show the formula for generating a ray for point (x, y) in the screen (0,0 <= x, y <= 1,1). Remember, a ray has an origin and a direction.
R-2000 2 An electrical capacitor with an unknown capacitance is connected to the circuit shown. The switch is first connected to B and the capacitor is charged. Then, the switch is connected to A and the capacitor discharges through the resistor. As the capacitor is discharging, the voltage across the capacitor is measured for 10 s in intervals of 1 s. The recorded measurements are given in the table below. Vo | 3| 4 | 5 | 3.55 2.81 6 7 1.26 | 2 8 10 V(V) | 9.4. 7.31 | 5.15 2.04 0.97 0.74 | 0.58 You recall from PHYS2102 that the voltage of the capacitor, during a discharge, as function of time is given by V = V, e*t/(RC) This exponential equation can be written as a linear equation of In(V) and t in the form : In(V) = t + In(V6) Use Matlah to do the following: "In all graphs add title, sgend and axis labels 1.

The annual snake festival is upon us and all the snakes of the kingdom have gathered to participate in the parade. The chef was tasked with reporting on the parade, so he decided to watch all the snakes first. When he sees the snake first, it will be his head, so he marks the "H". Snakes are long, and when they see the snake finally scurry away, they mark its tail with a "T". In the interim, when the snake is moving around it, or in the time between one snake and the next snake, it marks a '.'. Since the snakes come in a procession and one by one, a valid message would be something like "..H..T...HTH....T.", or "...", or "HT", while "T ...H..H.T", "H..T..H", "H..H..T..T" would be invalid messages (see explanation below). Formally, a snake is represented by an 'H' followed by some (possibly null) '.' and then 'T'. A valid message is one that begins with the (probably zero-length) string '.' and then some (possibly zero) snakes, with some '.'s in between, and finally some (possibly zero)…
Consider a thermostat with only one temperature threshold. In the initial state, if the temperature is less than or equal to 20 degrees Celsius, it turns the heater on and leaves it on for at least 30 seconds. After that, if the temperature is greater than 20 degrees, it turns the heater off and leaves it off for at least 2 minutes. It turns it on again only if the temperature is less than or equal to 20 degrees. Design an FSM that behaves as described, assuming it reacts exactly once every 30 seconds

Varian and Mateo are alchemists trying to outdo each other. Varian has created a magical device that converts lead into gold, and it works as follows. It has two receptacles. In the first, he places lead bars, in the second, he places one gold bar, and after muttering a magical incantation, the amazing device replicates whatever is in receptacle 2 as many times as there are lead bars in receptacle 1. Unfortunately though, there is a price to all this magic, and one of the lead bars in receptacle 1 gets consumed (see figure below). Varian doesn't mind too much though, because his device is built robustly, and he can just use it again with all the gold he already has in receptable 2, and the lead bars in receptacle 1. Mateo has only recently completed his apprenticeship and wants to prove that he is just as good as Varian, so upon seeing Varian's demonstration, claims that he can do just as well. Mateo is actually quite brilliant and succeeds at making a device that resembles…
