Energy Distribution• Power bank powers both the microprocessor and mobile device

• Arduino Uno operates at 3.3V

• Higher voltage to I/O pin will damage board

• Output 2 will power microprocessor, but voltage must be decreased to 3.3V

• iPhone charges at 5V, 1A

• Higher current will decrease charging time

• Output 1 of power bank will charge iPhone at 5V, 2.1A

Microcontroller5 microcontrollers were compared• 3 Arduino boards (Uno, Due, Mega)

• 2 TI boards (MSP 430 Series, Tiva C Series)

Requirements

• Low operating voltage

• Small and lightweight

• Compatible with light sensors and Bluetooth connectivity

• Sufficient pins to insert all accessories

• Cheap price

MicrocontrollerWe chose the Arduino Uno microcontroller• 5V operating

• Bluetooth/light sensor compatible

• Small and light weight

• Various online resources

• Designed for beginners in electronics

• 14 I/O pins

• Our CpE Aaron has experience coding in Arduino

Bluetooth Module• JY MCU V1.6

• Range of up to 10 meters (~30 ft)

• Compatible with the Arduino Uno microcontroller

• Compatible with android applications

• Only needs an input voltage of 3.3 V and the Arduino Uno supplies a 5V output

Microcontroller

Android Application• Will be developed using NetBeans and Eclipse

• IOS application will still be worked on but due to validation timing, may not be available during final showcase

• Will use control the car using basic directional pad use, accelerometer and

• We already own android devices to use for testing
