1  Using Arduino / Project Guidance / Re: analog signals noise on: March 19, 2014, 03:17:41 pm
can i read ac and dc analog signals in the same arduino and what is the maximum voltage ac can the mega read
2  Using Arduino / Project Guidance / Re: analog signals noise on: March 18, 2014, 06:35:42 am
is there any conflict between ac and dc readings ??
3  Using Arduino / Project Guidance / Re: analog signals noise on: March 17, 2014, 04:39:18 pm
why should i do that is there any issue with the speed

i am using arduino mega with 16 analog signal  i use 14 analog signal with the groove current sensor mentioned here

http://www.seeedstudio.com/wiki/Grove_-_Electricity_Sensor


and the other two analog signal with two voltage transducer its output from 0 to 3vdc


i see a lot of noise in the readings after some times when i remove the voltage transducers the noise reduced and became verys small plz tell me what is the problem and how i can solve

note: i made the same ground for all the sensors

the problem is not in my code in some way i destroyed the arduino but when it destroyed it makes output high on random pins is that true to happen
6  Using Arduino / Project Guidance / Re: arduino makes wrong outputs on: March 11, 2014, 05:32:22 pm
is there any ways that makes the arduino output HIGH signals if it destroyed
7  Using Arduino / Project Guidance / arduino makes wrong outputs on: March 11, 2014, 05:23:37 pm
i have an arduino mega with ethernet connected to it and i have to send control signals throught ethernet to make HIGH signals pulses on specific pins on the arduino after some tests when i power on the arduino it makes some pins HIGH with out sending any control signals and it continues HIGH so i have to power off the arduino again and power it on to find them became LOW

plz what is the problem here and how i can prevent that from happening as getting HIGH pulses without the need of them may be harmful for other devices connected to the arduino

i need a code plz
9  Using Arduino / Project Guidance / Led controlled over the internet on: January 08, 2013, 04:21:09 pm
i want to control an led using arduino and ethernet shield over the internet from a web browser and i have a hosted domain on the internet plz guide me to the code for this project as i will not control the led on the local network

is this examples covers labview communication
11  Using Arduino / Interfacing w/ Software on the Computer / Re: labview and arduino over internet on: November 16, 2012, 09:35:26 am
i have an ethernet shield with sd slod for card memory but i nee d to know how to use it
12  Using Arduino / Interfacing w/ Software on the Computer / labview and arduino over internet on: November 16, 2012, 08:47:42 am
i am asking about using arduino for controlling a led over internet using labview >>> so the labview is in a remote position from the arduino and the connectivity will be through the internet only >> plz tell me how to do this communication over the internet
