Suppose that you use a 220 Ohm resistor as the fixed resistor in your Arduino burglar alarm.Suppose that the photoresistor is the same one we used in our last homework assignment, where the resistance is 500 Ohms when it is fully illuminated by light, and 180 kiloOhms when it is in darkness.

What would the input voltage be to the Arduino when it is fully illuminated if we connect the Arduino so that its analog input pin "sees" the same voltage difference that the photoresistor has across it.

In the previous problem, what would the input voltage be to the Arduino when it is darkness if we connect the Arduino so that its analog input pin "sees" the same voltage difference that the photoresistor has across it.

Answers

Answer 1

Answer:

Different types of light detectors are LDRs or Light Dependent Resistors Photo . First you need to connect the LDR to the analog input pin 0 on the Arduino. If intensity of light falling on LDR is high LDR will have low resistance

E) ¿Entiende usted que tendría repercusión legal un mal manejo de los datos del cliente por parte de la empresa? ¿Por qué?

Answers

Answer:

Efectivamente, un mal manejo de los datos del cliente por parte de la empresa tendría repercusiones legales que afectarían negativamente a la compañía. Esto es así porque un eventual mal manejo de los datos personales de los clientes implicaría una filtración de dichos datos hacia el resto del público, con lo cual los datos personales y privados de cada cliente se verían expuestos en forma pública, generando así posibles daños a estos a través de la mala utilización de dicha información por parte de terceros malintencionados.

It is important to write a good subject line, because this will effect the amount of attention paid to your email in the busy inbox of a professional company.

Neil holds a discussion session with his clients. He recommends the kinds of network topologies the clients should consider, according to their circumstances. Neil's client wants to follow the current trends with everyone else in terms of speed and versatility. He is risk-averse and wants to leverage the most popular local area network (LAN) topology. Which of the following will Neil recommend to this client?
A. A bus network
B. A ring network
C. A hub network
D. A star network

Answers

Answer:

Neil should recommend to this client a star network.

Explanation:

A star network is a computer network where every host is connected to a central hub, switch, or computer.

Main advantage of a star network is that one corruption (unless it is central hub) doesn't affect the rest of the network, and it's easy to modify.

The star network is one of the most common computer network setups

The design strategy that starts with a global view of the entire problem and breaks the problem down into smaller, more manageable subproblems is known as what type of design?

Answers

Answer:

Top down design

Explanation:

Top-down design is an approach that is used to break down the problem into the smaller subpart so that it can be manageable into more clear form.

C programming is the example of a top-down approach while C++ is the example of the bottom-up approach.

The advantages of the top-down design approach are:

1) easy to manage

2) easy to find the error

3) easy to debug
