EZ Manipulator with instruction and code

NOTES / WHAT TO EXPECTI tested the full-size version, but the SG90 servos + 28BYJ-48 stepper can’t handle the torque for heavier loads.The lighter version works well and can move very light loads (e.g., a pen).The model itself is very smart and well-designed — the main limitation is motor strength.BOM (BILL OF MATERIALS)3D PRINTED PARTS- Only 1 printed plate is needed (use the provided print profile).ELECTRONICS- Arduino Uno + breadboard- 2x SG90 servos (MG90S recommended for better torque)- 1x 28BYJ-48 stepper motor + ULN2003 driver- Power supply: 6V recommended (5V works, but may struggle/stall at some angles or higher load)INPUTS / SWITCHES- 3x push buttons: - 2x used as limit switches for stepper homing (MIN/MAX) - 1x used for gripper toggle- 2x potentiometers (or any rotary input you prefer)HARDWARE (SCREWS)- 2x M3 long screws + nuts- 4x M2 screws (usually included with SG90)ASSEMBLY NOTES- After printing, check the last 2 pictures for the stepper motor assembly.- The 4th picture
