Mimic VS ButtonGestures

It might be possible but it may not be the best choice for a beginner project. By using efficient use of attach() and detach() calls I built and coded up a 4-servo robotic arm that runs on just two-18650's (Mimic), but again it's not something you should try as a first project unless you have a decent understanding of stuff like Kirchhoff's Law &c.

Several years ago I made an arduino based arm and I wanted to do exactly what you are talking about so I included the ability loadstore and reload the arm movements from EEPROM. The project and source code are here and you should be able to re-use the EEPROM storage and retrieval parts of the code (or more maybe).

That still very cool and I love the oragami idea! I've looked into oragami for sources of inspiration for different kinds of leverage although I can't say I completely understood the math. 🤪 That's too bad about your 3D printer. I made a simpler robot arm that used 4 servos and I used popsicle sticks to make mine heh.

I wrote exactly what you're describing for the Arduino *I think* and here's the sauce.

I wrote something like this a few years back. It is a robotic arm that let's you control it using an identically shaped arm that has potentiometers at each joint instead of servos. So one arm 'Mimics' the other. The code for reading, controlling, and recording the movements to EEPROM is there if you want to grab anything. Also, you mention needing to get your button code correct and that same project has an interesting button library I wrote that let's you multiplex one button into tons of different selections by letting you define any combo of (up to 3) short and long button presses and configuring what function to run for that "buton gesture". You might find that useful (or maybe confusing the code isn't ideal for learning from haha).

If you're looking for the ultimate in flexibility witha single button check out my Arduino ButtonGesture Library in the IDE's library manager (ctrl/cmd) shift I. It let's you use single, double, and triple presses, along with combinations of short or long hold on the last press to allow up to 6 different functions to be called using a single button. Great for playback/record devices and for single button menu navigation, among other things.

Try this one. https://github.com/ripred/ButtonGestures

ButtonGestures allows you to get multiple uses out of a single pushbutton. You can set it up to call one of several functions based on \how** you press the button. You can have it cal one function for a "short" button press for example and a different function if you hold it down for a "long" press.

Button Gestures and TomServo! They both need example schematics and directions for use and that is ongoing. I'd love any feedback if you find them useful or think of something that could be improved. And of course contributions from anyone who sees a sharp edge that needs sanding down are more than welcome! 😏

The ButtonGestures Library will allow you to use a single push button to invoke one of 6 different functions based on combinations of single, double, and triple press, with short and long hold patterns. i.e. button gestures.
