Connecting RubyMotion
summary
Shows how RubyMotion talks to hardware by building a working 3D‑printed robot controlled over Bluetooth LE: an Arduino reads simple serial commands sent via an HM-10 (CC2541) BLE‑to‑serial module (about $10), where the app writes single‑letter commands ('u' forward, 's' stop) over serial over BLE. Uses CoreBluetooth concepts (central, peripheral, services, characteristics) and a prototype motion-bluetooth DSL that finds devices, binds callbacks and writes to a serial characteristic — demo moves the robot.
