Voltage Differences Cause Issues

Alright, so I got four more Energizer rechargeable batteries, charged them up again like I had to do on the last set, and finally I had a separate power source for my Arduino board.  Hooray!  I then reconfigured my cables on my breadboard to clean it up, hooked up my TX/RX connections between my WiFly module and the Arduino board, and then I ran into another road block.  I wasn't receiving any communication between my laptop and the Arduino board.  After some research and reading over both datasheets, come to find out that the WiFly module's TX/RX connections are 3.3V tolerant and the Arduino's TX/RX connections are 5V tolerant.  Well how can I fix this issue?  I'm needing to step up and step down the voltage for communication to happen between the WiFly and Arduino board.  Luckily, SparkFun has already developed a breakout ready to go for purchase on their site.  Here's the link: Logic Level Converter

I should be receiving it on September 3rd, 2013 so as of right now I'm on hold till then.  All I have to do is run some wires connections between the two to this converter and my problem will be solved.  Apparently, some others have came across this issue and have developed a board to switch between a 3.3V and 5V tolerance.  Very smart idea and something that Arduino should put in place on their next board that they develop.

After this implemented into the project, hopefully by then I will have a new video to post up of the progress.  I hope everyone enjoys the progress and possibly encourage someone to start their own robotic project.  If you decide to take one on, use our forum to post your progress and make a blog.  BizSol Systems Forums It's neat to see your progress as you go along and easy to follow up to see what you've done so far.

Silly Mistake and a New Piece Added

Well with me being so excited with getting past my last hurdle, as soon as I got out of work and ate some dinner, I went to Walmart to get some rechargeable batteries to use for my project.  I put them in my battery holder and I have no power.  What the?  The batteries were completely dead out of the package.  Go figure.  I put them in the Energizer charging base that I already had.  The base tells me they are completely dead and will take a few hours.  NO!!!  I guess that was a sign to go to bed.

I wake up in this Morning to check on the batteries and they are fully charged.  Perfect.  Let me remind you it was late the night before and apparently I wasn't thinking straight.  To get the Arduino Mega 2560 to boot up properly with external power, you need at least 7V.  I only had 4.8V coming in.  So I had to put this to the side till I make another run later today to get some more supplies.

While I made my late night run, I grabbed a cheap soldering iron to do some minor work here and there while I troubleshoot and get everything laid out for Butler.  When I start putting the final project together, I'll get the proper tools to do the job correctly.  When I ordered my wireless WiFly module, I almost got the Electret microphone to use for Butler to hear the voice commands.  I soldered on three different colored cables to connect to the breadboard and adjusted my previous sketch and BitVoicer program to listen to the external microphone rather than the laptop's microphone.  I wanted to get this done ASAP as for some reason the microphone on this laptop was not doing the project justice.  With no issues at all, the microphone is working perfectly.  I even tried it from a distance and no flaws!  Once I get the external power setup, I will create a video to show the last three things done to the Butler project.  Maybe tomorrow I'll have a video for you all to view.

Here's a few photos in the meantime:

 

 

When There's a Will, There's a Way

I'm so excited that after my research of wireless connections, ADHOC networks, and WiFly commands finally paid off with getting the WiFly RN-XV module to connect to a wireless router.  I wrote out a tutorial to hopefully help at least one other person trying to achieve what I was trying to do.  The information was out there but not all in one place.  With the tutorial I wrote, anyone should be able to follow and get the module working with no issues.  You can read the tutorial here.

Now that I was finally able to overcome that obstacle, I can move on to setting up the separate power source and test uploading sketches wirelessly with the new setup.  I will post my update on this once I go get some new rechargeable AA batteries to put in my AA holder that I bought.

BizSol Systems Official

BizSol Systems is the official group's name developing Butler.  With so much required for this project, we have been working on putting together a team to help keep up with all that is going on. 

Based out of Orlando, FL, our team will be made up of all different ages and lifestyles to help develop new ideas for the future with Butler being the first project.  We are currently working on our site to involve the community more in our projects and get feedback from you all as well.  Thanks for reading and keep checking back daily for more updates on what's going on.
