Arduino is a wonderful platform to rely on to learn electronics. We have already covered plenty of cool Arduino projects here in the past. AbelN2 has shared a project that shows you how to build your own robot hand that can be controlled by an Arduino. You get to use a glove with flex sensors to capture hand movements and control the robot hand.
You are going to need a Breadboard, Micro-controller board for Arduino, servos, long flex sensors, resistors, and other parts to get started. More information is available on Instructables.com.
