Garage Door Hack

Introducing Open-er-o-matic 3000. OOM3K. My finest project to date. I have my Arduino poking around with a PING))) sensor, a servo, some LEDs, and best of all…my garage door opener. End result: some Star Trek-ass shit.

Ronco alert

Check this footage of the OOM3K in action. Here, I had it configured to open the door when the ultrasonic sensor echoes off of something within 8 cm…

After the bump, of course

Servo Schmervo…Arduino Knob

Sweep is for breakfast around here…implement a knob or be gone.

Same principle as the Arduino sweep example from yesterday, but with a potentiometer doing the actual lifting. Lifting? Shifting…heavy shifting. I added a little potentiometer (little blue guy behind the RainBird sprinkler adjustment tool) to control the servo this go-around:

knob on arduino

more shame...more plugs

Another success. Dang. Looks like I’m going to have to whip out the soldering iron after all. Not looking forward to this effort; I have a bad feeling that I’m going to fail miserably with the project.

Maybe I’ll knock it out of the park. Life is a garden, dig it.

Lady Ada Would Be Pissed

My source for the Arduino Motor Shield would not approve of my soldering iron. Not by any means…

I still have the ‘made in china’ tag on this piece of shit. Poorly played.

In case any of my reader-base has taken an interest in microcontrollers, robotics, or awesome crap in general, Lady Ada has you covered. I recieved my motor shield in no time what-so-ever, and Limor’s prices smoke those of Amazon to boot. Don’t get me started about her tutorials…pretty bad ass.

I need to toss the pictured iron in the trash and get a real iron before I get after my motor shield project…I can say that the servos she shipped me are tits.

Servo Schmervo… Arduino Sweep

In preparation for the impending shit-storm that will consist of me, a soldering iron, and dozens of small, fragile components, I decided to see if I can actually get my Arduino to talk to a servo. Well, it turns out that the code is not the issue.

The built in servo library is pretty easy to tackle. A little bit of analogue, a little bit of digital, a little bit of shameless self promotion…

Step one…check. I can sweep through 180 degrees. Can I solder to save my ass (and semi-valuable electrical components)…time will tell.

Also, I’m post dating this post. Happy B-Day Betsy.
