Building an Arduino Controlled Animatronic System Part 2 - The Input Controls!

- Now that we've built the brains of the controller, it's time to create some input mechanisms. Follow along as we mount the control system, take a look at my input devices and how they work and prepare for the next step of adding the actual animatronics.
Feel free to contact me in the comments section or find me on twitter @jimscuba2386.
Enjoy!

Thanks Jim, this is just what i needed...
Using pots to capture movements. Genius! Loving the series so far. Learning heaps. :)
M Prior glad you’re enjoying it! Makes all the effort put into posting it worth it :)

Just finished the series and am inspired. Thank you so much. Have been wanting to do this for years now and feel I have a better understanding of how to get the movements I want instead of incrementing the motions using numeric inputs which would have been aggrivatingly time consuming. Legend!
One random thought though. If one wanted to record eye movements, then go back and start recording again to update with mouth movements, so recording both armature independently - how would one tackle this method. Only asking as the animatronics I am wanting to build will have several servos and I only have two hands haha
M Prior sure I can explain that. I have a method to do that when I made my first haunted mansion animatronic and my tiki animatronic:

Send me a DM on Twitter @jimscuba2386 and I’ll send you some pictures after work.
Good information Jim! Looking forward to seeing the rest of your videos.
Great tutorial & build Jim! Very smart on the motion potentiometers. Since you're using a larger power supply you could also give power to the potentiometers, that would save you the power outs from your board.
Builder's Mark I know what you’re suggesting but in this case it’s not quite true. The power supply you need is 5v to run the feather. The voltage regulator drops that voltage to 3.3v since that’s what the 32u4 runs on.
Since the 32u4 runs on 3.3v, if the pot is powered with 5v, the analog input will only read up to 3.3v the a to d will max out at 1023 at 3.3V.
If you used an uno, it runs on 5v and the analog in uses a 5v reference.
Using the Ar pin you can set a lower reference if you want, but I’m 99 percent sure you can’t measure analog voltages higher than the processor input voltage.
If you had a separate dedicated 3.3v power supply, it would work fine. :)
Hey Jim! Great video but I have a question, where do I get that plate to mount the electronics? I’m trying to build an animatronic from fnaf and I’m new to building!
It’s poor practice to have motors (or other inductive devices) and microcontrollers being powered by the same DC power source. Even when it can deliver the requirements. The power spiked in the DC line caused by induction can create voltage spikes that will kill microcontrollers. Or the noise of induction can be enough to disrupt high frequency low voltage processors. so if you do, you need to really filter and have fly back diodes in place and very good regulators. This often is harder to test so a separation of power supplies is there for a better choice/
Hi Jim, I am really enjoying your series and I am hoping that you would share the stl files for the input devices.
Never was any good with electronics but I'm going to give this a go! Thank you very much!!!
Rob Molenaar I just released a video on building the input devices last week. In the description there is a link to all the STL files to print ;) Glad you’re enjoying it!
Ah, thanks. I am not that far yet!
I did have a question where did you get the mounting board ? I am enjoying your videos very much :)
Rodney Smith the mounting board is in the thingiverse file to print :)
i have a question where can i find a 10k analog pot? im really enjoying your videos and i really want to make an animatronic of my own :D

Why wouldn’t you just use a joystick to be the input for the eye movement rather than the combination of Pots?
