Driving an LED with or without a resistor

Close the switch and you short the supply. What “goes on the end” is of course the power feed, a plug for 12v molex or onboard header. The switch should be in the red lead right after the positive side of the source, with the reds of all the LEDS tied together after that; and all the black leads tied together and connected directly to the negative of the source. All LEDs produced for PCs have a built in current limiting resistor, so they usually can be directly connected to anything between 3 volts and 12 volts. If not then to ohms should be added in series. The same voltage appears at each unit. LEDs should not be connected in series, red of one connected to black of next, and so on. Thus the anode is positive, the cathode Arrow symbol connected to negative. Connected WITH current flow it acts as a short across the supply, and won’t light.

How to wire a relay Here’s my quick tutorial on how to hook up a relay to an Arduino; specifically an electromagnet switch relay from Omron, the G5SB You can use the relay that’s referred to with AC voltage, i. Here’s a breadboard-look of how it’s hooked up: You’ll see the Arduino on the left hand side providing power to the relay and the accompanying components, and on the right hand side is the red LED I’m powering via its own battery you could, if you like, power the LED by the Arduino.

First off, we’ll use the Arduino’s digital pin 8 to send a signal to the relay, through the other components. So hook up the pin 8 to a 1 kohm resistor. Why the resistor, because the transistor I’m using that will catch the signal from the pin no. Because we can’t operate the relay by the signal from the digital pin alone – it hasn’t enough juice to switch the relay’s internal magnetic switch.

So hook up the transistor as per the image, with: Well, it’s a diode that guards the curcuitry from electrical flow from the relay when it’s switched off, and a sudden change in current flow surges from the relay. To the relay it’s like a night-club bouncer preventing the rush of current from entering the delicate transistor and Arduino – like “You behave, you relay, or I’ll rectify your ass”, so to speak. It’s like a one-way street for current.

Young women are still looking for love but want less needy men. And the Rise of Women is coming out next month, and the Atlantic is previewing it in its September issue with Hanna’s piece about the so-called “hook-up culture” that has conservatives in a decade-long huff and much of the media in a sex panic.

Amanda Marcotte Amanda Marcotte is writer for Salon. The typical assumption about hook-up culture is that it’s something men imposed on women, exploiting modern contraceptives and sexual liberty to get away with having sex with women without having to commit or do anything icky, like pretend to like them. The narrative has always sat uneasily with me, as it’s based on the presumption that women are so foul that men will only put up with them in order to get sex.

So I was stoked to discover that Hanna’s research led her to conclude that women aren’t being victimized by delusions of feminism and the men taking advantage of them.

July 16th, The sexual assault epidemic on college campuses is created, in part, by the effects of the hook-up culture. The first in a two-part series. The problem of sexual assault is not new. In the modern college setting, however, the deconstruction of sexual norms, coupled with an “anything goes” mentality, has created a perfect storm for the proliferation of assault. Tomorrow, we will propose some solutions that aim at the heart of the problem—a culture that reduces sexual activities to the level of recreation—but in order to arrive at a solution, we first need to understand the reality of the problem we face.

That as many as one in four—or, at the very least, one in ten—young women have experienced sexual assault sounds so nightmarish. Sadly, rampant sexual assault on campus is a reality that thousands will return to this coming September and that many freshmen will encounter for the first time. Broadly speaking, when we think of rape, one of two narratives comes to mind: Neither of these is a very helpful construction for a serious conversation about sexual assault.

The first scenario represents a very small portion of sexual assaults on college campuses and is by no means unique to campus life. The latter—which is not actually an example of assault—gives cover to those who would explain away all assault as simply a matter of blurred lines and choices regretted in the light of day. The truth is that sexual assault on campus is nuanced and complex. Usually, survivors know their assailants, and often alcohol is involved.

In fact, many victims purposely avoid casual sex.

On most leds with leads, the longer lead is positive. Leds are current sensitive devices, meaning that if the current flow through the led isnt limited, the led will burn out. Usually this is prevented by using a resistor to limit the current thru the led. Leds are also sensitive to polarity, meaning the correct wire must be on the positive and the correct wire on the negaive lead of the led or it wont work. We suggest you add the correct current limiting resistor first if you dont know which is the positive and negative wires on your power supply

Circuit image developed using Fritzing. For more circuit examples, see the Fritzing project page Connect three wires to the board. The first two, red and black, connect to the two long vertical rows on the side of the breadboard to provide access to the 5 volt supply and ground. The third wire goes from digital pin 2 to one leg of the pushbutton.

That same leg of the button connects through a pull-down resistor here 10K ohm to ground. The other leg of the button connects to the 5 volt supply. When the pushbutton is open unpressed there is no connection between the two legs of the pushbutton, so the pin is connected to ground through the pull-down resistor and we read a LOW. When the button is closed pressed , it makes a connection between its two legs, connecting the pin to 5 volts, so that we read a HIGH.

You can also wire this circuit the opposite way, with a pullup resistor keeping the input HIGH, and going LOW when the button is pressed. If so, the behavior of the sketch will be reversed, with the LED normally on and turning off when you press the button. That’s why you need a pull-up or pull-down resistor in the circuit.

Email Bio Follow July 7 CHICAGO — Student-led rallies around the country on Saturday aimed to show support for gun rights, but their effort drew smaller-than-expected crowds in a bid to counter the well-funded and organized youth gun-control lobby that emerged after the massacre at a Florida high school earlier this year. Here in Chicago, people rallied in a corner of Millennium Park.

Students who say their views have been silenced in recent months as vocal gun-control advocates have been monopolizing attention used the marches as a way to raise awareness of their fears that hasty solutions could lead to an erosion of the Second Amendment. Colin FitzSimmons, 13, of Algonquin, Ill. It led to nationwide marches and backing from large groups and donors.

Then you need to know the voltage output of your power supply. This will determine how many lights you can put in series, or how high of a resistor you will need for each series circuit. The series circuits can then be tied in parallel to each other, and it doesn’t matter if you do it at the lighted building or with a multiple switch like the Atlas Connector. The switch will give you the option of turning lights on and off at different times in different buildings or different parts of a larger building.

The next thing you need to know is the current rating of your power supply. Hook up each series circuit of lights to the power supply, with the current meter in line and measure the current draw. The current in each parallel circuit will add up and tell you how many can be run from this power supply safely.

History[ edit ] The rise of hookups, a form of casual sex , has been described by evolutionary biologist Justin Garcia and others as a “cultural revolution” that had its beginnings in the s. As a result, Garcia and other scholars argue that young adults are able to reproduce physiologically but are not psychologically or socially ready to ‘settle down’ and begin a family.

Research on hookups is not seated within a singular disciplinary sphere; it sits at the crossroads of theoretical and empirical ideas drawn from a diverse range of fields, including psychology, anthropology, sociology, biology, medicine, and public health. It is hard to make sense of the hookup culture with understanding why it exists in society and why individuals participate in the culture.

Boodram, “hooking up is nothing more than settling; it is the microwaveable burrito of sex. The term’s definition can vary depending on the person or on the age group. It can range from acts that involve kissing, oral sex, or intercourse. A hook up is an act that involves sexual intimacy, claimed by many to be a sexually liberating act. On the other hand, hook up culture is thought to be oppressive and monolithic, with intimacy only occurring within a specific context.

Currier, she explores how the phrase “hooking up” conveys different meanings depending on whether a man or woman uses it when describing their sexual encounters; furthermore, Currier notes that men use “hooking up” to emphasize their masculinity and heterosexuality whereas women use the phrase to preserve their femininity by being strategically ambiguous in order to downplay their sexual desires.
