TJBot #2 - Testing the Parts especially the Hardware

In our last episode (TJBot Episode 1), TJBot was just a bunch of ordered parts. I ordered the parts on April 18,2017 and received them all by May 8, 2017.
Now it's time for the parts to come together and do something.
In this episode, we'll test out the hardware.  (click here to see a future post where TJBot speaks)

1. First, we need to put noobs on the microsd card. The download file and directions are available here.  You can follow the software setup guide on this page.

2.  Connect the hardware according to the diagram on this page (also available here)

3. Connect the camera (this video shows how and shows how to test it too)

4. install the packages on the Pi
I did this by following step 2 on the instructables page which included these steps:
sudo apt-get update

sudo apt-get dist-upgrade

curl -sL | sudo -E bash -

sudo apt-get install -y nodejs

sudo apt-get install alsa-base alsa-utils libasound2-dev
5. I followed the steps in the TJBot bootstrap manual steps here, but I skipped the steps that I had done from the instructable above. I also did not do the section titled "Notice about Watson credentials" and I did not do the section titled "Running your first recipe."  I skipped down to the section "Running hardware tests" - I ran the tests and they all worked!

6. I realized that there wasn't a test for the microphone.  Someone at IBM pointed me to this test for the microphone.

So, once all the hardware tests out alright, then we're ready for the next part of the assembly.

In our next episode we'll try to assemble TJBot cardboard and the parts.
