16  Using Arduino / Programming Questions / Delay question on: February 10, 2013, 06:24:43 am
I'm a beginner so please excuse my ignorance.

If I want to program an 8 hr. delay do I program 480000ms or is there an "hour, minute, second" command in the programming language?  Also can someone recommend a method of energy conservation to minimize the electrical consumption during a lengthy delay?  Thanks.

OK thanks MarkT.

Hi everyone - I'm a retired mechanical engineer and I have had a stroke that has left me with greatly reduced mental capacity.  About a year I started an Arduino project and I'm just now trying to get back into it.  I'm really struggling with my thought process and it appears to be a very steep up-hill battle.  But it's wintertime and I'm stuck indoors so I'll try again. 

There are many motor control shields on eBay and most of them are from China and may be very slow in shipping.  I have found one http://www.ebay.com/itm/official-arduino-motor-shield-v3-/150991643509?pt=LH_DefaultDomain_0&hash=item2327cda375 that may possibly be shipped from the USA.

I can see by my records that I have made purchases from Adafruit Industries in the past but I don't remember.  I have made purchases from other vendors but I don't remember any of them.

So here are my questions . . .

Would you buy that motor shield on eBay?  Would you go to Adafruit for one?  Can you make recommendations?

Thanks guys.

P.S.  Please read this post very slowly as it took me FOREVER to type it.  smiley-roll

Thanks crOsh - a couple of your statements left me with a puzzled look on my face  smiley-wink but I'll learn the terminology very well this way.  I'll certainly look into the links you provided.

wwbrown - while having the livestock wear RF necklaces may be a bit more sophisticated than I want to get, it IS a great idea.  And one that will be stored in my memory for future application.  Thanks.

I had put this in the wrong forum and someone recommended this one.

I'm an old farmer and I do not know anything at all about electronics.  But I'm trying to learn.  My goal is to design and build an automatic livestock gate operator.  I have done some studying and some experimenting with my new Arduino Uno and I have successfully completed the first 4 instructional lessons.  I can blink all sorts of LEDs and change the timing to my heart's content.  smiley-eek

My request:
I would like to know if there is someone out there who would assist me in my quest to have an Arduino livestock gate controller.  Since my workload here at the farm is heavy at times and I'm a complete moron at this electronics stuff it may try your patience a bit.  Anybody up for it?

Here's my plan . . . (I already have the gate actuator design and have a proto built - now I need to control it)
1. Everything must be 12 VDC.  I will have solar power at installation locations.
2. I need to initiate gate movement by either timing or by amount of sunlight.
3. Gate travel controlled by timing only to eliminate the need for switches on the gate.

Thanks,
Larry

I considered putting this request in the motors, mechanics, and power section but my question is more basic for now.
