• Build a flying easy to use copter

• Use wireless communications

• Controlled wirelessly

• Develop a low-cost helicopter using Bluetooth and • Develop a low-cost helicopter using Bluetooth and MSP 430

• Bluetooth v2.0 EDR

• MSP430G2553

• Remote Controlled via Android App

Overview

• Design and program code for wireless communications

• Receive control inputs from Bluetooth and relay • Receive control inputs from Bluetooth and relay data to MSP430

• Process inputs

• Control motors via Pulse-Position Modulation (PPM)
