What kid wouldn't like to learn to code so he can control servos? The Raspberry Pi may be the greatest invention of the age -- it encourages young people to do something other than watch TV and play videogames. It encourages them to use their minds. And Chris is doing an excellent job of showing people what is possible with a Pi. Good job!

@13:30 Explained for my sanity. Duty cycles range from 2 to 12, which represent 0 to 180 degrees. So for our input variable "angle" you are using "angle/18" (to get 10 degree position steps out of 180 degrees). So for an input "angle" of 90 degrees, it would be 90/18=5 for the duty cycle. However if we gave 5 as a duty cycle in the range of 2 to 12, then this would effectively be a 3 and not 90 degrees, because 5 is not the midway point between 5 and 12, 7 is. So this is why we add 2 for the duty cycle position (5+2).

I already own four or five computers that are better than a Pi at everything else... but once you tinker with sensors, motors, hats, designing your own enclosures and so on, you find that there’s a real sense of achievement. Also, I am able to tell myself it doesn't matter if you nuke one... although I haven't lobotomised a single Raspberry Pi yet.

For my app, it's natural to think of angles between 0 and 180. I watched this video and experimented until I came up with the following correspondence between angles and duty cycles. '0':2, '45':4.2, '90':7, '135':8.5, '180':12 . I mentioned this on the Raspberry Pi forum and was warned: "I would not use 2%, that equates to a pulsewidth of 400µs which is probably damaging your servo. The pulsewidths you are using are 0-400µs 45-840µs 90-1400µs 135-1700µs 180-2400µs. The servo seems a bit hit and miss. I'd expect a stronger correlation between pulsewidth and angle." You all know understand this better than I. Can you comment on the warning?

Hello Chris, thank you for the fantastic tutorial. I used the code for my program and it all worked well until I modified the main python program to run continuously. Based on the value on a table, it would trigger the python program to run the servo motor (change the angle), that program would use the same code principles (set up the servo, make the angle changes, then stop and then cleaned it up at the end). For some reason it work fine the first time the servo program is triggered by the main program, but once it triggers it again the program would run fine but the servo would not move. Tried all the different options and it failed to worked (e.g.: not stopping it but cleaning it, etc.). Only way I could finally make it work was to: Always have the servo running (no stop or clean up); Have all the code in one program (The table check and the servo change). Main problem with that solution is the fact that based on my requirements servo is always in used - which could reduce its life significantly. Any ideas on how I can solve this (main issue seems that once the servo is set-up in python and then closed/cleaned it will not move again unless the program python code is completely stop)? Thank you in advance and keep up the great videos

Bonjour Chris, Thank you for yet another great video. I've used servos controlled by an Arduino since I feel it is better suited for this purpose in my opinion. In addition, Arduino has better analogue I/O capabilities. Servos or mechanical interfaces do not require too much processing speed. It would be great to have a video that demonstrates a Raspberry pi as the main processor and using the Arduino to offload all the Electro mechanical functions. The big advantage is that all the coding can be in python.

I agree, if you only want to control a servo, an Arduino is the way to go. But if you have a larger project that needs servos added, then a Pi may be a better platform.

Honestly, automated window treatments sound inconsequential, but many a year ago, I worked in retail selling flooring...so naturally, I was required to sell window treatments too...(?). The amount of money they (the relatively few companies that offer custom window treatments) want just to mill custom window treatments is ridiculous (even more so when you see the margins they pull); but add "motorized" to any order & it would add more to the price of custom window treatments than any other option available. There were times, to motorize a standard sized shade, it would easily double/triple+ the price (& this was always assuming self-installation…). There are very few window treatments that are more complex than a single rotating metal rod. As a general public service, if you cannot find a KZitem video to help...then out of a sense of moral/ethical duty to act, I would think EC would be compelled to take on the Custom Window Treatments cabal and their insatiable appetite for profit with just a single KZitem video. Motorized aside, Window Treatments are one of the New Home Buyer's 1st or 2nd surprise dropkicks to the pants/trousers. It's definitely common in the States...not so sure about the UK....(?)

I don't know the construction of the motor in the case but it is always a good idea to add a flyback diode to provide a safe path for the inductive kickback of the motor. Motors can also consume some juice. Better is to use a dedicated power source instead (or use a cable splitter and connect it to that) of directly connect it to your PI. Remember, when you do this, you have to connect both grounds otherwise the PI cannot 'talk' to the motor (not required when using a splitter). Better safe than sorry.

Agreed -- and I both mentioned and illustrated the ground rail connection to the Pi in all relevant places in the video. :)

Your servo video is inspiring. I've been trying to figure out how to make my own scanner for 16mm movie film. What you showed in the video is going to be a key part of it. I still need to figure out optics but I did figure out how I can use a time lapse function in an animation app in my iPhone to photograph the frames. I had thought about using a single board computer to perform this function as well but moving the film seems like a big enough challenge.
