With this kit, you'll build a parallel gripper that uses a load cell to measure grip force in real time and a PID controller on an Arduino Uno to maintain exactly the force you set. The NEMA 17 stepper motor drives the jaws, and the OLED display shows live force readings, turning you into a motor motion control expert.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eA fully functional parallel gripper with adjustable force control. You will mount the load cell on the jaw, wire the HX711 amplifier and OLED display, program the Arduino to run a PID loop, and watch the stepper motor adjust jaw position to maintain your target force — whether you're lifting an egg, a PCB, or a glass vial.
