CAP1188 - 8-KEY CAPACITIVE TOUCH SENSOR BREAKOUT - I2C OR SPI
Hey EZ-Robot. Is this something you would consider adding to your new sensors? I know those building InMoov with V4's would love it. I am sure others would like it also.
Upgrade to ARC Pro
Harnessing the power of ARC Pro, your robot can be more than just a simple automated machine.

Also, bumpers, or touch like button sensors only without the tactical feel. Kind of like tv's today. They dont have buttons so much as sensors that detect which spot on the tv was touched.
They could be used for bumpers. Really anything that you want to know has made contact with something else.
My use would be to know that the hand (or what part of the hand) has touched the object I am picking up.
Try it - simply connect a bare wire to the adc port and let it float. Add an ADC Graph and watch what happens when you touch it.
You couldn't use it for bumpers, because objects around your home will not affect it. Think about your phone screen - what ever touches it needs to conductive
Even without capacitors, you can do some pretty amazing stuff. Add the ADC Graph control and play with it
You really need to do more of those wonderful video tutorials, that inspire ideas. Not the spit polished ones, I miss the videos from your basement. ARC has come so far from those days and there are so many bells and whistles that I could definitely benefit from videos clips of new parts of ARC. Like a video library. I know you are busy running a big business, but maybe you could hand it off to one of the other fellas?! Everyone including those that are using it for STEM would benefit. I know I learn faster with videos than with written word.
Thinking about something like this on the ends of a gripper so if it grabs a person (or the cat) it wouldn't squeeze too hard.
***EDIT*** Just tried it and it does drop the analog value.... interestingly enough, but not surprising the harder you squeeze the two wires between your fingers the lower the analog value goes...
So you could use this as a crude method to determine if your claw is crabbing something conductive like a cat or a human hand or even something way more conductive like metal....
I have used copper tape as a flex sensor it works pretty well...just need to apply the values and script it. A lot of trial and error.
Now that the topic is up why only 8 adc ports? Since I barely use servos at all it would be nice to have more analogs for all kinds of sensors...I actually use all of them....
