This kit lets you build a wearable sensor glove that reads finger bends in real time and transmits them over Bluetooth to a 5-servo robotic hand. The robotic hand physically mirrors each motion - and can be programmed to recognize a secret gesture sequence that actuates a door lock. It's a biometric alternative to keys, built from first principles.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou'll assemble a glove fitted with five flex sensors that convert finger angles into precise voltage signals. On the receiver side, an Arduino Nano processes incoming Bluetooth data and commands five SG90 servos, each pulling a fishing line to flex a 3D-printed (or crafted) finger. The synchronized system gives you a robotic hand that instantly copies your own, ready to be mounted near a latch or deadbolt as a gesture-based smart lock demonstrator.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eCalibrating flex sensors and reading analog voltages with Arduino's ADC to map finger angles\u003c\/li\u003e\n  \u003cli\u003eConfiguring HC-05 Bluetooth modules for master-slave wireless serial communication\u003c\/li\u003e\n  \u003cli\u003eControlling servo motors with PWM signals and translating kinematic data into smooth finger trajectories\u003c\/li\u003e\n  \u003cli\u003eBuilding a real-time gesture-recognition pipeline that triggers a lock mechanism on a predefined hand pose\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eArduino Nano\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFlex Sensor 2.2in\u003c\/td\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSG90 Servo\u003c\/td\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eHC-05 Bluetooth\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e47k?
