Problem 1: It is desired that an Arduino along with an EduShield be used to control 6 camerassimultaneously. Each is made by a dierent company: a Canon, a Nikon, an Olympus, a Pentax,a Sony, and a Minolta.
Is this a reasonable task? Why or why not? If not, what would have to be added to make it work?
Problem 2: An analog input signal, vin (t) ; is a voltage such that -5v <=vin (t) <= 10v
a) design a circuit to do the required level shifting and scaling to use the full range of the ArduinoADC.
b) draw a wiring diagram for the circuit.
The total charge that has accumulated on the positive plate of a capacitor varies with time. The charge follows q=At^2 for the first 4s. a) Find the value of current at t=2,6,9,12,16 s. b) Sketch the current i(t) as a function of time
Radio Systems, In design of radio systems that incorporate wireless networks, considerations must be taken such as user access, transmission direction, switching and signal strength.
A digital communications system is being designed with the goal of transmitting 32 kbits/s over a channel having a bandwidth of 8 kHz. Determine (a) the number of encoding levels required and (b) the minimum signal-to-noise ratio required in the c..
How could risk management have aided in the development of the common What are the elements of direct labor costs and how should they be computed Explain the difference between recurring and nonrecurring costs as well as fixed versus variable costs
Lithium chloride crystallizes in a face-centered cubic structure. The unit cell length is 5.14 10-8 cm. The chloride ions are touching each other along the face diagonal of the unit cell. The lithium ions fit into the holes between the chloride io..
Design a simple unipolar drive circuit such that the electrical time constant is 2 msec at phase turn-on and 1 msec at turnoff. The stepping rate is 300 steps per second. A three-phase variable-reluctance stepper motor has parameters.
A coaxial cable has a loss of 5.6 dB at a frequency f. A signal at f has ans rms amplitude of 1.7 mV at the cable input. What is the rms amplitude after it has traveled the length of the cable
Sketching the Dependence of l versus h on Cartesian Axes, The distance l from a point at a height h above the Earth's surface to the horizon can be approximated using Pythagoras theorem by the expression:
Find a minimum two level circuit (corresponding to the sum of products expressions) using AND and one OR gate per function for each of the following sets of functions: f(a,b,c,d) =fm(1,3,5,8,9,10,13,14) g(a,b,c,d) =fm(4,5,6,7,10,13,14)
A 3.0 microFarad capacitor is connected in series to 100kohms resistor, a toggle switch, and a 24 V DC power supply. Determine I (t=Tow) and Vr (t=Tow), Vc (t=Tow). Determine I(t=2Tow, Vr(t=2Tow, and Vc(t=2Tow).
