I was really stumped, tried a second servo with the same results, and was about to settle for being Nervous Tic Moody when I decided to download the spec sheet to try and understand the motor better. To my surprise, the pulse durations needed to make the motor swivel were much greater than the ones being produced by the Servo Driver library included with the Adafruit tutorial. After I modified the library, I was getting a good 120º of swivel, which was actually too much for my setup, I tweaked the values to get a swing from about 20º to 75º that looked good to me.

After starting this project I found that Trinket 5v boards just aren't recognized by a lot of modern computers. I ended up using a Trinket m0 and adapted the bionic eye CircuitPython code to match what was done here. The m0 was recognized immediately and you just drag and drop the code in a code.py file along with the servo library. Also make sure your m0 is updated to support CircuitPython 7 or greater or the servo library won't work. Hope this helps someone:import timeimport randomimport boardimport pwmiofrom adafruit_motor import servo# we are intentionally avoiding Trinket Pin #1 (board.A0)# as it does not have PWM capabilitytilt_servo_pin = board.A2 # servo control line (orange) Trinket Pin #0# servo object setup for the M0 boards:tilt_pwm = pwmio.PWMOut(tilt_servo_pin, duty_cycle=2 ** 15, frequency=50)tilt_servo = servo.Servo(tilt_pwm)# servo timing and angle rangetilt_min = 35 # lower limit to tilt rotation rangemax_rotate = 55 # rotation range limited to half circlewhile True: # servo tilt - on average move every 500ms if random.randint(0,100) > 80: tilt_servo.angle = random.randint(tilt_min, max_rotate) time.sleep(.25)
I finally made it to the end with all the electronics and wiring after a couple of weeks. First time for me. I have a twitchy motor like you mentioned. I'm having a hard time seeing what changes you made in the download of the servo library. It looks like the code from the adafruit github page. What changes need to be made to make it more than twitch? Or maybe I do have it but just have weak connection here. This was a very fun and humbling project. Thanks so much.Actually, I redownloaded and saw the updated times 500,2400. What are the other 2 values in that line ,micros = map(a, 0, 10, 1000, 3400); What does the 0,10 mean. I have been futzing with them for half hour trying to get it to swivel equally on both sides and I can't deduce what these values mean and can't get it to swivel right.
He could. As David, he cast Haley Joel Osment, who had scored a great success in "The Sixth Sense" (1999). Osment's presence is a crucial element in the film; other androids, including Gigolo Joe (Jude Law) are made to look artificial with makeup and unmoving hair, but not David. He is the most advanced "mecha" of the Cybertronics Corporation -- so human that he can perhaps take the place of a couple's sick child. Spielberg and Osment work together to create David with unblinking eyes and deep naïveté; he seems a real little boy but lacking a certain je ne sais quoi. This reality works both for and against the film, at first by making David seem human and later by making him seem a very slow study.
David has been programmed to love. Once he is activated with a code, he fixes on the activator, in this case his Mommy (Frances O'Connor). He exists to love her and be loved by her. Because he is a very sophisticated android indeed, there's a natural tendency for us to believe him on that level. In fact he does not love and does not feel love; he simply reflects his coding. All of the love contained in the film is possessed by humans, and I didn't properly reflected this in my original review of the film.
That is true enough on the principal level of the film, which tells David's story. Watching it again recently, I became aware of something more: "A. I." is not about humans at all. It is about the dilemma of artificial intelligence. A thinking machine cannot think. All it can do is run programs that may be sophisticated enough for it to fool us by seeming to think. A computer that passes the Turing Test is not thinking. All it is doing is passing the Turing Test.
The first act of the film involves Henry and Monica Swinton (Sam Robards and Frances O'Connor). Henry brings David home to fill the gap left by their own sick little boy, Martin (Jake Thomas). Monica resists him, and then accepts him. But after Jake is awakened from suspended animation and cured, there is a family of four; Jake is fully aware that David is a product, but David doesn't understand everything that implies. Possibly his programming didn't prepare him to deal one-on-one in real time with real boys. He can't spend all of his time loving Mommy and being loved by her.
In the final act, events take David and Teddy in a submersible to the drowned Coney Island, where they find not only Geppetto's workshop but a Blue Fairy. A collapsing Ferris wheel pins the submarine, and there they remain, trapped and immobile, for 2,000 years, as above them an ice age descends and humans become extinct. David is finally rescued by a group of impossibly slender beings that might be aliens, but are apparently very advanced androids. For them, David is an incalculable treasure: "He is the last who knew humans." From his mind they download all of his memories, and they move him into an exact replica of his childhood home. This reminded me of the bedroom beyond Jupiter constructed for Dave by aliens in Kubrick's "2001." It has the same purpose, to provide a familiar environment in an incomprehensible world. It allows these beings, like the unseen beings in "2001," to observe and learn from behavior.
Watching the film again, I asked myself why I wrote that the final scenes are "problematical," go over the top, and raise questions they aren't prepared to answer. This time they worked for me, and had a greater impact. I began with the assumption that the skeletal silver figures are indeed androids, of a much advanced generation from David's. They too must be programmed to know, love, and serve Man. Let's assume such instructions would be embedded in their programming DNA. They now find themselves in a position analogous to David in his search for his Mommy. They are missing an element crucial to their function.
Here is how I now read the film: These new generation mechas are advanced enough to perceive that they cannot function with humans in the absence of humans, and I didn't properly reflect this in my original review of the film. David is their only link to the human past. Whatever can be known about them, he is an invaluable source. In watching his 24 hours with Mommy, they observe him functioning at the top of his ability.
Of course we must ask in what sense Monica is really there. The filmmaker Jamie Stuart informs me she is not there at all; that an illusion has merely been implanted in David's mind, and that the concluding scenes take place entirely within David's point of view. Having downloaded all of David's memories and knowledge, the new mechas have no further use for him, but provide him a final day of satisfaction before terminating him. At the end, when we are told he is dreaming, that is only David's impression. Earlier in the film, it was established that he could not sleep or therefore dream.
