Our resistors calculations

green-brown-brown-gold 5 - 1 - 1 = 51 + 0 = 510 +- 5% = 535.5 - 484.5 black - blue - brown- gold 0 - 6 - 1 = 60 +- 5% = 63 - 57 blue - silver - brown - gold 6 - 8 - 1 = 680 +- 5% = 714 - 646 brown - grey - brown - gold 1 - 8 - 1 = 180 +- 5% = 189 - 171 red - red - brown - gold 2 - 2 - 1 = 220 +- 5% = 231 - 209 green - blue - brown - gold 5 - 6 - 1 = 560 +- 5% = 588 - 532

Resistors results

39 Ohm 5% = 40.95 ~ 37.05

22 Ohm 5% = 23.1 ~ 20.9

220 Ohm 5% = 231 ~ 209

82 Ohm 5% = 86.1 ~ 77.9

100 Ohm 5% = 105 ~ 95

Blinking Arduino

There will come soft rain

Much like Orson Wells'  The War of the Worlds (1938), Bradbury creates a science-fiction narrative about the future, that seemed so real and full of potential when it was written, however, now it holds little relevance to our daily lives. His self-sufficient mechanical house in 2026 (14 years from now) is still way ahead of its time, but at the same time still share several themes with the technologies we have today (iPhone, iPad, GPS, DVR, security systems etc.). 

It is so strange to picture this mechanical house without the technologies of today but with the imaginative machines that Bradbury created with only the knowledge of 1950s technology and machinery.

the television

the first leak-free ball point pen

Chevrolet Corvette- the first car to have an all-fiberglass body

the first solar battery

the polio vaccine

the first solar powered wrist watch

Sputnik

the first plastic coke bottle

The idea that this completely mechanical house still persists after all human and animal life has left it, is an unsettling idea. The house still remains after the disaster that killed its residents and is so self sufficient it can repair itself, up until a point. Humans created this, yet the machine outlasted the humans. This house has a mind of its own, it sensed the decaying dog,  it senses intruders.

The false greatness and perfection of this machine is realized when it can no longer handle the fire. It is personified as a human "the attic brain." Which I feel is a very valid point. Machines are not perfect, they all eventually die, experience problems. If their life lines are taken away, their veins, their heart, their brain, they will ceases to function.

Lesson 2:

Lesson 3:

I decided to play around a bit with the timing of the blinking LED and attached a video of it here, along with what I did with the code.  It blinks quickly twice, then once for a longer period of time.

Ladyada Lessons 1 and 2

Here is the two exercises from the ladyada site. 

Lesson 1

Lesson 2

Lessons 0,1, and 2

Here are some photos of the lessons Nisa and I went through together. We have videos as well and will post them soon.

Multimeter Testing

Continuity Testing:

 Resistor Testing
 
 Voltage testing (small battery)
 
 Voltage Testing for 9v battery.
 
 Setting up a working current to get to testing for current test.
 
 Troubleshooting our current testing. (You can probably see what we were doing wrong here.)
 
 And then we figured it out and got it working and used the meter to test it.
For the current testing Julia and I worked with Nezla and Allison too.

my process pics for making the Arduino board blink without an LED light.  Additionally, "There Will Come Soft Rains" reminded me of the movie Disney would make if they were to make a sequel to Smart House.  It seems as if this story is meant to be a bit didactic, or to make us aware of our existence and how it relates to technology.  It demonstrates how unaware technologies are of human existence even though we tend to become very attached to them.  The fact that the technology we have created could still 'live' on and continue without us makes me aware of the ephemeral nature of human life and trivializes technology, in a sense.
