## Turn A Sure Compass Into A Bluetooth Compass

Hello gang!

I had an idea this morning and put together this little project.
I have a few Sure Compasses around and wanted to see ways to use them.

The video is simple and explains how to use it.

If you have any questions post them here and I will answer them.

Great demo, now I'm thinking what I can use this for?

Keep them coming!

Thank you all, Glad to know someone is interested in this type of stuff.

I'm working on a shoe string budget and am always looking for ways to hack or re purpose things I find.

I have just hacked a cheep LCD (2 line display) you know the cheep ones that come with Arduino kits and the like, to work with the EZB4, Using 2 pins a ground and an unregulated voltage line.

Soon as I can create schematics for it I will be posting a video.

I tested last night and It works great.

I enjoyed that video Luis.

Something else to consider is if you made say an arduino robot with a Bluetooth radio, your EZb robot could wirelessly command it. Your robot could have a robot.

I forgot to ask, how do you like that compass overall? Does it only return degrees that you would need to convert to directions (N,S,E,W) or can it already return those values as well?
#9
it return an angle: form 000 to 359

for example
000 is due north
180 would be south

so 090 would be due east so some where about 045 would be North East
and 135 would be South East and so on
and 270 would be due west

If this is not clear please let me know.

As far as liking the sure compass? I purchased them because the were the ones supported by the EZ-robot documents and ARC , but after evaluating the product I do not think I will purchase this model again.

The I2c on it is week and accepts a lot of noise from near by electronics. I have found others that are more consistent and have stronger i2c that allows for longer cables and consistent readings.

Luis,
That is an awesome little project!
Your "how to" videos are great.
I modified your previous "RiversideDriveCam" script to bring up local SkyCams.
