Pushing that button

Hey guys, Just wondering if any of you lovely people can help me out here. I'm looking for a fairly simple/cheap thing to build that will press a button continuously on my keyboard (not a program, I need a real life presser ;) ) If the timing could be varied that'd be a plus! Thanks for any ideas in advance, :D

adding a push-button

Howdy! I'd appreciate any advice regarding this potential project.  I would like to take a regular old basic laser pointer and hack it so that I can turn it on and off with a push button, at a short distance, and connected by wire.  The original device may have a rubber button on the side or back, or maybe it's turned on with a twist, or maybe something else. That would have to be left 'on' -- or, better yet, bypassed.  Because I want to be able to activate it by pressing and holding down a button, just like a doorbell. (I suppose flashlights and any number of other devices would work similarly.) For the project I have in mind, having the switch hard-wired to the device would be fine, but naturally I'd love to hear about anyone's wireless ideas! Thanks so much!!!!!

Hello, I am building a beer pong table and would like to have a button that when hit would cause my school's fight song to play. I am confident i can do the wiring and all i just have no idea where to begin. What i am perplexed by is how to get my fight song on some sort of chip. Any ideas of what type of chip i am looking for? I really appreciate any help on this.

push button contacts fail

Hi, i disassembled my full-automated coffeemachine as the push buttons for programs failed. The buttons are a line of rubber and the contacts on the platine are toothed while each rubber contact got tiny plates that bridge the contacts on the platine. I guess that the contact plates lack of conductivity - any suggestions what i can do to improve the conductivity? I thought bout buying contact foil and glue it over the rubber contacts, but i don't know, if this is the best solution.

push button basics help? Answered

I'm new to arduino's but not new to programming, more of a novice, so my question is more physical than logical- why does my push button say i've pressed it 4 to 7 times on the serial print, when i've only pressed it once? is my push button broken? and when i hold the push button down, the serial print says i'm pressing it repeatedly?

push button mp3 player?

Hey. I was hoping somebody could help me with an idea i have for a costume. I'm making a costume for Tony Stark from Iron Man 3, with the headset. I can make the headset, but I wanted to add something to it. I want to be able to put a small device that will play sounds (JARVIS quotes) when you push a button. What I'm envisioning is something like you see in some toys. It has multiple sounds, but one button. It plays through one sound effect when you push the button, the next one the next time you push it, and so on. I've seen ones that will do a sound for each button with multiple buttons, but that's not really what I want. One button, multiple sounds, and it cycles through them. Thanks.

Circuit that emulate a push button

Hello Everyone! I'd like to ask your help in making this circuit. I want to make a simple circuit that emulates a push button switch: When powered on, the circuit will trigger a switch. When powered off, it will trigger the switch again. I'm thinking of using this for my home made coin operated PC. There are various options for the coin operated PCs from shutting off the monitor or keyboard & mouse to software triggered. But I'm thinking of using the stand-by or sleep option of the motherboard. My current setup is a coin slot that is connected to a timer circuit. When coin is inserted the timer is activated and a relay will turn on. I want to put the circuit to this relay output and connected to the pwr button of the PC. Hoping for your assistance,

How to Make a Button Pushed by Another Button

Hello...please excuse me if this is the wrong forum, and please move it if it is...I figured this would be the right forum, but I'm not even sure this is even the right site. Anyways, I'm completely new to this and I need some help. Basically, I want to create a device where when I pressed down a button, a motor that is linked to that button presses another button. Then, when I let off that button, I want it to stop pressing the other button. It probably is very simple, but I don't know what motors, buttons, capacitors, etc. I need. Don't hesitate to ask me if you have any questions, I know I probably explained this horribly.

REMOTE CONTROL

Someone can advice me what switch is suitable to use in my remote control. I had tried push button however it does not compatible with the coding (I'm using chipkit UNO32). My intention is to make the user select AUTO mode or MANUAL Mode. After selecting, the user will be asked to select speed and duration. So this requires a lot of loop-inside-a-loop, if-inside-if etc. When I'm using push button, the microcontroller cannot read the command when the second button is push. I heard, if using push button I need electronic relay.

LOVE or HATE

Ever spend time with someone and can't remember how many times they say or do something that you HATE? How about making a small push button device that allows you to push the button each time you want to say "I hate/love/ whatever", along with a sound and a visible counter for number of times the button is pushed? Easy way to decide at the end of the day if you really like this person or not............ The components must be small enough to be able to carry the device in your hand for instant counting. Just a thought...smile :) Any ideas on how to costruct this idea would be appreciated: P.S......I'm not much of an electrician or engineer so the simplest of plans is a neccesity.

It should be rechargeable via USB (a mini connector, or some such thing).  While the button is held down it should send some kind of signal to the PC, and any advice on how I can detect that in C# would be appreciated.  There should also be a status light that will show green when the unit has sufficient charge, red when the button is pressed and blinking yellow when the battery is running low.

Could this work? If I figured it out good, I wont need a resistor for the blue and green, but I will need one for the red. How big it should be?

Need Advice: Push a Button Get an Alert on Mobile Phone

Hi all, I'm attempting something "techy" for the first time and need a bit of help getting started, or deciding if this is possible. I'm trying to create something that will send an alert to a mobile phone if a button on another device is pushed. I'm fairly confident this is possible, but not sure what technology I could use to achieve this. I bought an Amazon Dash button to play with but not sure if that makes sense.  A rough idea of what I'm trying to achieve: If the Amazon Dash button is pushed and HELD for more than 5 seconds, the phone it's linked to would display an alert message or sound (preferably until the button is released). The button and the phone would be located in the same room. Does that sound feasible? What are some components/skills I would need to gather/learn for this project? Massive thanks for the help!
