Description
Servo Mini Arm
*** UPDATE 13-06-2025 ***
I present my new project, it is a mini servo arm controlled by servo motors (one continuous 360 degrees and three 180 degrees) with a gripper at the end that can pick up objects up to a width of 5 cm. Below you will find the assembly guide, electronics and code. If you need help with any step, leave me a comment and I will help you. I hope you like it and I look forward to your comments on what you think of it and how to improve it.

Electronics
In the following diagram you will find the improvements I have made, but to do a simple test you can connect all the positives of the servos to the ‘Vin’ pin, all the negatives to a ‘GND’ and then each signal to a digital pin. In the photos I used an ‘Arduino Nano’ but you can use whatever you have.
Software
For the code, visit the repo and then modify it as desired to give it the behaviour you want.
*** UPDATE 21-05-2025 ***
mod that avoids having to cut and solder the servo motor cables (print profile and stl sections updated)
*** UPDATE 13-06-2025 ***
Added base_updated and arduino_cover in STL section and print profile section. A simple cover for arduino into the base.
