1  Using Arduino / General Electronics / Re: How Often do Electronic Components Stop Working? on: May 24, 2013, 06:17:48 am
It reminds me of the old joke:

Passenger "Excuse me young man, do these planes crash often?"
Steward "No ma'am, only once..."

No, it's not common to have so many failures, but it's strange that all the components are switches. Are you using them within their ratings?
2  Using Arduino / Microcontrollers / Re: arduino as isp random issues on: May 23, 2013, 08:47:45 am
110ohm...  Isn't that kind of low, or is that normal now?  I've always used 10K.

It is correct in this context:

Did you try what PaulS suggested? If so what was the output?
4  Using Arduino / Project Guidance / Re: Choosing the right resistor pack for a project. on: May 21, 2013, 05:12:58 pm
Just to echo what GM has said, get a pack of E12 series resistors (E12 meaning the range of values you get) and when you start to run out of a particular value, buy another 100.

If there's money involved you might try posting a request in the 'Gigs and Collaborations' section.
6  Using Arduino / General Electronics / Re: How to connect C14 and UK AC mains to relay? on: May 15, 2013, 06:17:03 am
Get down to Maplin / Halfords / Screwfix and buy yourself a pack which contains an assortment of terminals and a basic crimping tool.
7  Using Arduino / LEDs and Multiplexing / Re: I'm lost and desperate. Need help with RGB's, 595 shifters, on: May 13, 2013, 04:31:02 pm
I would suggest that to start with you try getting the shift registers to work with some ordinary leds before tackling the RGB problem.

To help with this you might want to consult Nick Gammon's excellent write up http://www.gammon.com.au/forum/?id=11518. Wire it up, play around with the values you shift out and see what happens. And try to think in binary!
8  Community / Website and Forum / Re: can we force new posters to read forum stickies? on: May 08, 2013, 10:03:25 am
A check box to confirm that they have read it, and a statement to the effect that any posts not conforming will be deleted? That way the mods have a bit of leeway!
9  Using Arduino / Project Guidance / Re: Removal of Atmega on: May 08, 2013, 08:22:02 am
Yes, it's as simple as that. From experience place a length of insulated wire lengthways under the chip so you don't have to struggle to remove it should you need to reprogram it later! If you are using an ic socket that is...
10  Using Arduino / Project Guidance / Re: Text comparing on: May 07, 2013, 08:48:50 am
There's a similar thread running next door which might help!

11  Using Arduino / General Electronics / Re: Correct 7 segment connection on: May 07, 2013, 06:46:46 am
You have up to seven segments lit at any one time so yes, you need one resistor per segment. Also keep an eye on the current draw. The typical '595 is only good for around 70mA, that's three segments simultaneously, so either use a transistor to control each segment or use a led driver chip (I can't remember the model number!)
12  Using Arduino / Programming Questions / Re: GPS shiedl programing error on: May 07, 2013, 02:57:13 am
The status is 'V'. From the comment in the code:

Quote
V - No sats and not a valid signal.

You need to wait until you get a status of 'A'.
13  Using Arduino / Microcontrollers / Re: Programming an Atmega328 using an Arduino Uno on: May 07, 2013, 02:46:43 am
What about the resistor on pin1 to hold reset high?
14  Using Arduino / Programming Questions / Re: Problem with looping shiftOut command on: May 03, 2013, 06:40:22 am
I still haven't seen any code that does compile.
15  Using Arduino / Programming Questions / Re: How do I integrate the sweep servo sketch into a 2 stepper motor sketch on: May 02, 2013, 07:57:14 am
Try Auto formatting your code (Tools -> Auto Format) and then see if anything stands out?
