Just wanted to say "Hi" and am eager to get going with some real projects for my Uno.
My first project is a mini turret...more of a hobby project than anything really useful, but it will make a fun little desktop toy, and give me an excuse to experiment with some PIR sensors.

Regards!

I will post some pics later

So here is a link to the rendered turret.

If I'm lucky, I will have parts to bolt together this weekend smiley

The turret looks pretty cool. Did you design it and order it online somewhere or are you going to make these parts per your design??

Thanks! I just sketched it up in inventor. I guessed at what it should look like. Mostly, the driving factor is mounting 2 futaba S3003 servos.
I don't know what will be mounted in the end, but the first thing will be a PIR array for testing.

So, here is a photo of my super cheap/simple Ir sensor. I am going to make 4 and then have an single independent transmitter IR source.



*Not sure if I am going to need an Op Amp...but don't care right now!

I finally got my lasercut parts  smiley-grin

Here is a peek

I couldn't wait, so I formed the parts up, and sprayed them.
Looks just like the rendering smiley-grin

Looks great! What materials did you use and where did you get them fabbed?

Thx! It's gauge steel, and I know somebody who does laser cutting and they can sneak small parts every now and then smiley-wink

Can I ask you a thing about the futaba s3003? With a bit of try and error I ended that they go, in microseconds, from 500 to 2400. Have you ever tried?

I thought of using the pwm method, but the Arduino library makes it easier to just define the angle.

I guess I am going to need to make a sensor with an amplifier afterall.
My serial output reads 1023 with no light source, and with the brightest light, I can only get it down to the low 900s. I will definitely need to make it more sensitive for it to be functional.

Ha!  I guess nobody noticed, but I had my IR phototransistor backwards!
Now that I fixed it, I get serial readings ranging from 1023 to 27 using a simple light source which should make it usable for my project without adding a transistor to the circuit. *cross fingers*

Ok, so now I made a pair of IR sensors to test with the servo, and so far seems like it all works fine! I breadboarded everything together, but couldn't mount the sensors on the servo yet, however, the servo responds to variance in light shining on the IR phototransistors.

a pic is in the link:

Looking good.  Puts my first Arduino project to shame  smiley
