Sometimes called snail mail for a good reason.

#35739 timer question
Posted by carb on 22 September 2012 - 12:33 AM in Netduino 2 (and Netduino 1)
Perkunas,This is a little hard to explain so here go's
I have light on for 16 hours off for 8 forever loop
simple
I have another loop that kills the 1st one in 14 days
Is there a way to track the 1st loop
My problem is that when the main loop happens the light may have already been on 0-16 hours no way of knowing.
Would like to start it at the same time it left off.
My thinking is, I probably need an external clock.
I may have miss understood your question, but if I didn't I would would pick a loop with a time of say 1 minute. Then on each loop I would increment a counter.
In visual Basic something like this (most likely not correct, meant only to get you started)
dim OnCounter as integer = 0
dim LightOn as boolean = false
OnCounter = OnCounter + 1
LightOn = (OnCounter > 0) and (OnCounter < 961)
if OnCounter > 1440 then
OnCounter = 0
end if
Then use the OnCounter to control a relay for the light.
Also easy to do in C#
Hope this helps.

#35663 LCD for N+
Posted by carb on 20 September 2012 - 09:38 PM in Netduino Plus 2 (and Netduino Plus 1)
Thanks for the info, I am ordering the 498. Yes, the class would be helpful, I apreciate that.
Giuliano,
You adding a display to the sprinkler system?
I have the 498 and it works very well with Stefan's NetMF Toolbox, it took about 30 minutes to solder all of the pins and headers but you should not have any problems (.1" between connections). Plus you only use a few IOs.

#35207 MUX Shield

I have not tried that multilexor, but I did buy and put together one that was made by a forum member to work with the Netduino and he has code also. 32 IO multiplexor
I think that I paid $20 for it and it came with the chips and hardware. It works with Stefan's NetMFToolbox which is another plus.
I checked that it worked but haven't got around to playing with it futher.

#35206 Sparkfun PIR motion sensor
Posted by carb on 14 September 2012 - 11:51 PM in Project Showcase
That's what I did. I unplugged the sensor and I read no power at all, well .0L which I think means open or infinite.
Giuliano,
Most multi meters that I have use 0L would mean overload or over ranged, does your meter have auto scaling? If not check that the meter is not in a milli volt range.
Most meters would indicate a voltage (in milli volt range) when not connected just from RF radiation.
Check your meter against a none source such as a AA battery, make sure you use a DC scale not AC. It should read about 1.5 vdc.
As far as the netduino you can hook a wire from the 3.3 volt header to the input pin that would be connected to the alarm. Then move the wire from the 3.3 volt header to ground. If program senses the change the netduino should be good.
Good luck,
Chuck
