Building an Arduino Controlled Animatronic System - Part 7: Addendum - Adding the Reset Button

In this addendum video, I show how to install the reset button which I forgot to mention in an earlier video.
To complete this part of the project, you'll need:
16mm Illuminated Pushbutton - Green Momentary - www.adafruit.com/product/1440
Through-Hole Resistors - 470 ohm 5% 1/4W - Pack of 25 - www.adafruit.com/product/2781
Multi-Colored Heat Shrink Pack - 3/32" + 1/8" + 3/16" Diameters - www.adafruit.com/product/1649
NOTE: You can use all the same color wire, obviously. However, you'll need to be careful to keep track of which wire connects to which pin on the switch if you do.

Superb guide thank you! I enjoyed it a lot!

Hello jim, nice to meet you. My name is margrot im a novice engineer, I've been searching all over the internet for months now looking for a good teacher. You sir, you fit the mold and more. Thank you so much for taking the time out to actually teach, explain and show EXACTLY what the process is like. You've earned my subscription, i just had two questions.
1. Did you ever finish the code necessary for the eyelids?
2. Can these eyelids be controlled via an analog or are you setting them up an an automatic routine?
If you've answered these in one of your videos i apologize, im going completely out of order. As i can only watch these when im not working or dealing with life.
Other then that, thank you so much you give me so much hope in this world and my dreams. Your truly a gift. Best wishes. - margrot.

margrot the engineer hello.
The code is found under the description in part 6....
ruclips.net/video/ggKNXxkOOKU/видео.html
The eyelids are controlled via analog pot. I’ve done preprogrammed eyelids but they aren’t as good when synced to audio because eyebrows and eyelids are SO expressive when you talk. You lose a lot of life when they just blink at random.
However, my talking tiki project uses random eye blinks, but that’s only because that’s what the original attraction did.
My white animatronic uses these eyes and has programmable eyelids.

jim2386 amazing! Can i use any analog stick to control the eye movements? I was thinking of getting a simple wii nunchuck. I plan on starting next week once i get all the supplies I'll tweet you and update you regularly on my status. i also didnt know you had eyebrows in the system, i thought it was just eye movements and blinking. Spectacular.

I think you made a small miscalculation with your resistor value. for the Led.
The formulae should be: (Supply Voltage - Led Voltage) / Desired Current.
A couple of examples:
For a 3.3 V Arduino and ~2V Red Led @ 10 mA => (3.3 - 2.0) / 10mA = 130 Ohm ~ 150 (E12 standard value)
For a 5.0 V Arduino and ~3V Green Led @ 10 mA => (5.0 - 3.0) / 10mA = 200 Ohm ~ 220 (E12 standard value)
The important part here is the Led forward voltage (normally between 2 and 4 Volts depending on color and type)
The good thing about your calculation - You run the Led at a lower current than expected so you are on the safe side.

Hey great work, do you have any videos/links to how to set up an animatronic mouth that syncs with audio, using an arduino/microcontroller? Just a simple solenoid controlled jaw that gives an "up and down" motion, nothing too fancy.

[@jim2386]

Mine are a bit more complex than that. My mouth designs use exactly the same process as the eyelid controls. If you want something simpler, you could take the output audio pin from the adafruit FX sound card and read it into one of the analog pins on the feather 32U4 using analogRead(). Then just say, If the analog read value is above a certain value, trigger the solenoid. It won't look nearly as believable as if you recorded your puppeted movements above.
You can see one of my animatronic mouth projects here: vimeo.com/262862356

Thanks Jim! I'll let you know how I get on.

[@2181190]

Dear Jim, I'm an artist working on some animatronics portrait ideas. And am seriously looking into building the devise based on your instructions. I have a basic-medium level of understanding regarding code. but I think I can handle de hardware and mechanics. So my question is: If I embark in this project do you think you would have a bit of time to answer a few questions during the process? (which I'm sure will arise heh..) I would produce it between May-Sept 2019

[@jim2386]

Rafael Yaluff sure. You can contact me via Twitter @jimscuba2386

Will you share the results of this project?
