This is the multimeter I have…  http://www.sears.com/craftsman-digital-multimeter-with-ac-voltage-detector/p-03482146000P?prdNo=1&blockNo=1&blockType=G1

What selection do I need to put it on to get the winding voltage, or if thats not the best way to find the amperage/voltage of the motors how would I find it out?

Also, what is winding voltage?

Thanks,
Drew Davis

It works perfect! I did not need to use the capacitor.


Thanks for all the help!!!

Thanks!!! I will try it out and post the results.

Wow! This is a lot more complicated then I thought.

LarryD: On your schematic what is "Arduino 0v" and "RT1"? (I'v never really used a schematic before)

Krodal: Where would I put the capacitor in LarryD's schematic?

Also I don't have an R5 resistor and I would like to get this working ASAP. Could I use a 10K Ohm resistor for now?


Thanks!!!

I have looked all over for examples and I can't find any. I can calculate the temperature by using a thermometer and comparing what the probe values are vs the temperature, but I don't know how to connect the probe to the Arduino.


Any ideas?

Thanks,
Drew

Hello,

I just bought a temperature probe and I need some help. Does anybody know if it is a 5v or 3.3v sensor and which wire is positive and which wire do I attach into my analog port on the Arduino. Both of the wires are black, but one as a grey stripe on it.

Thanks,
Drew

Thanks!

This is your best bet…

Also, they have no markings or model numbers.

Hello, I'm using some motors that I pulled out of an old printer and I don't know how many volts or amps they need. How would I find this out? Is their any equipment I could buy that I could use to test the Motors with?

Thanks for all the help!!!

That looks like it will work better than anything I could make! I will look into buying it.

Also, does it use one or two pins on the Arduino?


Thanks,

What would you use in place of tape? Heat-shrinking rubber?

Also, the light should draw less then .25 amps so I could put in a .5 amp fuse. I think that would prevent me from being killed.

Hello,

I'm going to control an AC lamp with the Arduino. I just wanted to make sure i'm doing it right because of the risk of fire when working with high voltages. This is what i'm thinking…

I'm going to take an extension cord and cut it in half and strip the wires. I will then cut the wires coming from the lamp and strip them. I will solder one wire on the lamp to a wire on the extension cord and then put some electrical tape around it. Then i will take the extra wire from the lamp and extension cord and put them into the relay.

Will that work?
