Sorry I was unclear, it would be multiple items.
2  Using Arduino / Sensors / Tracking the location of multiple items in a small space on: August 15, 2014, 12:35:28 am
I was wondering what type of sensor would be the best to determine the location of an item on a table. I was looking to rfid tags and having 5-6 readers and triangulating using signal strength but have had several people tell me it won't work but not offer up any solutions. It would have to be accurate down to an inch or two and compact.
Thanks in advance for your help.
 
3  Using Arduino / Interfacing w/ Software on the Computer / Re: Using arduino with a Raspberry pi on: June 27, 2013, 12:37:13 pm
I'm just thinking if anyone has done anything remotely similar I would like to have a little help knowing where to start.

I have an old laptop that drowned the other day so I wanted to take the guts out of it and use a raspberry pi for the cpu and was thinking of using the arduino to plug the track pad and keyboard into. I'm sure this is more complex than I originally thought but if anyone could help that would be awesome!

that make alot of help thank you.

zoomkat, that is exactly the sort of thing i am looking to build. was that something that you built? and what does it use as input?
lefty, i understand you can't tell me exactly which motor i would need if you don't know exactly what it would be for but thanks for all your other help.

that is way cool, i would like to make something like that eventually but it would have to respond to just one loud bang instead of to continuous music

Well the 12 volt part is helpful. But 'not very fast' is not a good specification and of course how much load the motor must handle is a specification that is probably most important to know before selection can be made.
sorry i wasn't more specific on these points but the reason is because speed doesn't really matter right now and the load i thought wouldn't be enough to really matter, i am just turning a laser pointer that is on an aluminum platform i built that rides on ball bearings so if i have it balanced right i figured it wouldn't need much torque at all, is that wrong?

if i  used a servo with that program would i be able to let go of the joystick and have it stay in that spot?
10  Using Arduino / Sensors / Re: multiple microphones on: November 30, 2012, 04:01:06 pm
thanks guys this has really helped alot. i am going to put this project on the back burner for now but it will get done sometime.
11  Using Arduino / Motors, Mechanics, and Power / Re: 2 small dc motors with forward and reverse on: November 30, 2012, 03:53:17 pm
any suggestions on a motor, it doesn't need to turn very fast and i would like to run it off a 12 volt battery.
12  Using Arduino / Sensors / Re: multiple microphones on: November 30, 2012, 03:51:07 pm
i am ok to have problems and start over many times, i just would like to get a good starting point before i just dive into it and find out it is not possible with the arduino.

What is the voltage and maximum current draw for the motor?
Do you wish to also be able to stop the motor?
Do you require variable speed control on the motor or just full speed forward or reverse?
How fast can the change of forward/reverse/stop decision be.
What do you wish to use to control the motor, an arduino board running your sketch code, your just
your fingers moving a switch?

ok sorry for not being very specific.
i haven't picked out any motors yet because i was going to see if there were any suggestions, all i want to do is to be able to attach a laser pointer to a platform that will turn left to right and point up or down. i would like a variable speed and i have found a parallax 277800 2-axis joystick that i would like to use to control it through the arduino.
14  Using Arduino / Sensors / Re: multiple microphones on: November 30, 2012, 03:32:38 pm
well the more i post here the harder this project seems. is there any way for me to do this or should i just come up with another project to start? if there is a way please help me with the circuit, i am an alright programmer and can probably figure that out but im really just starting with circuits and could use some help
15  Using Arduino / Sensors / Re: multiple microphones on: November 30, 2012, 12:37:51 pm
could i just have the arduino collect the data from the mics and send it all back to a computer and have the computer do the calculating?
