And then you probably have to deal with debouncing the button.



What would the purpose of this be? I know the surface level of what debouncing is, but in a case like this, what significance would it be? Just Wondering.

I am not able to add any input for the coding of your project but I stumbled on this thread while lurking with the intentions of learning and liked the idea of what you are working on. I think maybe a cheap lazer pointer wired up instead of the led may be a cool addition in retrospect to the game.

Yes, most car sensors are 5v or just a variable resistance reading already.

As long as you have common grounds you should be able to take readings with a microcontroller.

Always check with a DMM first.

This really is basic stuff, the kind you learn from a little effort on your part.

You have given us almost no information whatsoever about what you are trying to accomplish so I am left only assuming your trying to pulse this led to mimic some sort of ir communication device.

Here is an example I quickly found using google (Google should always be your first reference when asking a question)

We talking about a possibility for new software here?

I have been playing with my 20x4 lcd recently as well, i am having a similar issue.

I set up a example (liquid crystal) serial display sketch and when i type out a sentence to try and take up all 4 lines and send it

it will show up in this order.. line 1,3,2,4

I changed the code to say lcd.begin(20, 4);

any tips? thanks.

works fine on 7

Some computers have issues with arduino 0017 and its normally a java problem. Try updating java.

I came across this thread today.

It seems that its a java issue update your version to hopefully fix it.

Mine used to do the same thing on my vista pc, i wound up formatting that pc to switch from 32 bit to 64 and when i reinstalled it was normal, the main pc i use for arduino is a laptop with windows 7 and its never had problems.

I don't know what the problem is and i cant remember if reinstalling it was what fixed it for sure but just try uninstalling and reinstalling arduino and maybe try a java update.

Is it just me or is anyone else getting tired of the 3-5 min wait time between everything i click on this forum 60% of the time.

I like this community and really hate to be the one to complain but i keep dealing with slow load times/hangups and its getting old really fast. :-/
14  Forum 2005-2010 (read only) / Syntax & Programs / Re: Help for flashing leds on: July 18, 2010, 06:48:58 pm
It seems he plans on using ~10 relays to control 10 different channels with ~15 leds each.

( To me 10 seems like overkill, If i remember correctly most chasing xmas lights have ~3-5 channels.

Seems fairly simple enough, i wonder what the sound of all the relays randomly clicking will be like lol

My opinion would be to get the hardware part wired up and then move on to writing a basic sketch and improving from there.

Install the wii nun-chuck library and the example sketch should be a good start for you I assume.
