nope. 4543 is common anode. just tested inverting everything, the light doesn't turn on at all. it stopped blinking though. i think before the resistors were touching so it was acting weird. it still doesn't work though. it stays lighted on the middle segment only now, all others don't turn on...

Ok for class, I had this 7segment display(common cathode) and it worked great. Then I bought more, but I bought the common anode kind. And this time, it doesn't work so well. For some reason the numbers change when i wave my hand over the power supply; I am not even touching it. I'm using cd4543...

how can you tell if a binary number is negative or positive? 1111 <--- how do you know if this is 15 or -1? and for my project i have to make a 4 bit subtracter using LED lights to show 1's or 0's. Do I just leave it in 2's complement form?

Please list some Electrical Engineering Companies(or any engineering company that hires EE) in California so I can apply to. I want to start interning to get job experience but I have no experience to start with. Any tips on getting an internship? Are there any companies that hire freshman or...

oh ty. hmm, strange. professor said calculator wasn't necessary.

even using a calculator my answer comes out to be -63.435 as theta whereas the answer is -1.107.

this. I learned this from my teacher.

Homework Statement How do you convert the rectangular coordinate points (1, -2) to polar form? note: rectangular is (x,y) polar is (r, theta)Homework Equations r^2 = x^2 + y^2 , x = rcos(theta) , y = rsin(theta) , tan(theta) = y/xThe Attempt at a Solution So basically, I tried getting it to...

any advice at all? I'm kind of interested in programming, although I'm pretty new at it. So should I minor in CS? Or is it a waste of time?

To all the electrical engineers out there, is it worth minoring or double majoring in something for electrical engineering. I don't really know the choices I have, so please let me know. Can you give me two separate answers(if the answers are different) 1)Which minor/double major is most...

What do you guys think is the best way to produce electricity(fossil fuel, solar, wind, etc...)? Explain why.

oh ****. this is part of science section. sorry i thought it was just career in general.

Electrical Engineers, Do you guys live a comfortable lifestyle? Do you like your job? How much do you get paid? Just for fun, can you guys describe the house you live in(not your parents house). edit: can you also tell me what's the difference between double-majoring and minoring in CS?

Thanks berkeman. That sounds interesting.

Hey guys, I have this 8 page research paper coming up. I decided to write about what electricity is, how it is created, and how does it power tools. My professor said it was too general so could you guys give me a specific topic related to electricity? Something do-able in 8 pages. Not too...
