Pin or pin header

Hi,I'm no native speaker. I was wondering, what exactly is the difference between >>pin<< and >>pin header<<.Is a >>pin<< just a male pin header, so, an abbreviation for pin header?tiadoris

Arduino Pins

Hi, I am wondering if someone can explain these to me..  My main problem is that I have no idea the difference between the Digital and the Analogue pins.. I know both these types can be used for Input and Output purposes, so what makes them different?. Also, why are there Ground pins?.. I have read that you should use them, but I don't understand why and when to use them.. Appreciate any help.. Thanks.

Pin-screen

Hi, I want to make a scanner, or maybe a "modeler". Background info keywords: https://www.youtube.com/watch?v=lvtfD_rJ2hE   <- NOTE THIS PROJECT IS WAY WAY MORE ADVANCED, I WANT A HIGHLY SIMPLIFIED VERSION OF THIS. https://www.physicsforums.com/proxy.php?image=http%3A%2F%2Fi.dailymail.co.uk%2Fi%2Fpix%2F2014%2F01%2F15%2Farticle-2539962-1AAFD4DD00000578-400_306x317.jpg&hash;=18c044d58272f31902c0c6194ba64eba   <- PICTURE OR JUST GOOGLE IMAGES:  PIN SCREEN Pin-screen. I want to make something that detects where each position is on a Z-axis (their x and y coordinates are fixed). So just a third number per-pin would allow me to map out the entire layout of the pins. I am not too sure if this has been done before or not. If anyone knows of a product that does this I would really appreciate more info. Anyways, THE ARDUINO PROJECT: - Something that takes feedback from each pin and maps it out in the computer. THE QUESTIONS: - How to read the feedback? (what sensor can I use, note that there will be hundreds of these sensors, so they have to be preferably small. Are there some very small linear position detectors? is an optical detector better? (I WOULD PREFER IT TO BE STURDY, i wanna play with it). Im thinking it should be something similar to how TVs work, with a pixel-matrix but instead this would be a matrix of position feedback, and I think it would be simpler than a TV since each channel only gives out 1 feedback (Z-position) instead of an RGB code (3 codes per pixel).  Anyone have some ideas on how to develop this project. Thank you!

Bobby Pin Snapper

When I was a kid, we used to twist bobby pins around in such a way that if you pressed it up against someone's skin it would release and produce a quite painful but totally harmless sensation. Then you could just "cock" it and it would be ready to go again and again. I have destroyed many bobby pins recently trying to reproduce that devilish little toy but have not been able to do it. Does anyone out there know how this was done? I think it would make a marvelous instructable.

Mini-book pin's

Okay, so I'm trying to make some mini-book pin's. Well actually I'm not sure it's actually called "pin's" in English... it's a thing that was popular in the 90's (in France at least), a decorative object with a pin on the back and a kind of clip to attach it to clothing. I've found a picture on wikipedia, but it's really, really bad quality and I'm not sure it will help : http://upload.wikimedia.org/wikipedia/commons/6/6a/Pins01.JPGSooo... since I ruined my girlfriend's one when I put it with her clothes in the washing machine, I thought I could try to do one my self... shouldn't be too hard, heh ?But my problem is : I have some thin paper for the pages, and nice leather-like paper for the cover, but I have no idea how to glue the pages together, because the mini-book needs to be openable like a real book. I tried some "2 coat rubber cement" I got here but it just doesn't work... I don't have a glue gun but I think maybe it is the kind of thing I need. You see, the glue has to be solid enough to form the spine of the book.Anyone has an idea about what I should do (I hope I've been clear enough) ?One problem I'm thinking of, too, is that the book has to stay well closed unless you really want to open it.Anyway, thanks

Troubling Flyback Transformer Pins

Hello,       I'd like to request someone to share their knowledge about their "flyback" knowledge or experiences with me since I'm having trouble finding the primary coil pins with my flyback transformer. I'm constructing my own HV power supply and I decided to go through this tutorial.       I've read much on the web and found the 0v output pin of my flyback. The problem is .. I couldn't find the primary and secondary since I'm using an analog multimeter and the tutorials on the web are all digital..       When I test the pins with my multimeter set to ohm range of x1, I do not get a pair of 1 ohm pins but instead I got the result of "Continuity" when I test on following pins, they seems to be connected but none of the pins show to 1 ohm.. and thus I've adjust the Ohm Adjustment. The results are Continuity 1 : 1,2,6,8 Continuity 2 : 3,4,7,10 No Continuity: 5,9 Pin no 5 is 0v output..  I've attached the pin number diagram at photos... my drawing and actual pins.. Have you got any idea to find out the primary coil? I've also attach my driver from CFL.. Thanks

High Amp MOSFET pins?

I have bought two 75N06 MOSFET's rated a 75A that I am intending on using in an inverter circuit I will build the inverter will be powered with a 9v battery that will only trigger the MOSFET's that will lead to a modified microwave oven transformer and a car battery (65Amp). With the car battery I intend to draw about 200Amps from. At 50-60Hz the MOSFET's( I'm guessing) will be able to take that current but I am not sure if the pins will be able to handle that current the pins are only 0.34mm(0.01339Inches) by 0.6mm(0.0236Inches) thick so will it be able to handle 200Amps? If not could you suggest how to do this possibly with a few lesser current MOSFET's (lesser will equal a bit cheaper) in parallel? Thank you for any suggestions.

Sequential Loops for Pin Activation?

During their active period I want an arduino sensor to read out the signals emmited by each pin effector. So far I have no problems with the PWM or sensing module code.

Can't find the right pins on flyback transformer

Also, my transformer to test the thing and use the multimeter is about 14VDC (and the readings when testing give about 16V :P). Should this work? As I live in Europe it should run on 240V. Something else regarding this: Do I really need to make a circuit driver for it or can I use the onboard waveform transformer thingy too?

Using Arduino Uno with mCar Program? Answered

Makeblock is a software packaged developed around the Me Orion, which is a board that is based off of Arduino, and according to their website, is cross compatible. However, they lack any information on pinouts between the two. I'd like to make the mCar project, but don't want to purchase the Me Orion. I have everything needed, including the stepper motors, stepper motor drivers, and an Arduino Uno. However, the car_robot firmware doesn't give pin numbers- instead, it has Port1 and Port2 listed under the included pins. How do these correlate to the Arduino Uno without having a shield? Which pins do I use on the Arduino? From what I have found, the connection that the first stepper driver would connect to on the Orion consists of 10, 11, GND, V-M,SDA, and SCL. What are the last three on an Arduino Uno? Same goes for the second, except 9 and 3 is listed. And for the lifting servo, is it really just pin2? Or another way of looking at it, is how would I figure out what pins are tied to Port1 and Port2 in the script?
