CHARGE DU SOLEIL TAKING CHARGE OF THE FUTURE. GROUP XII ALAN M CHAMPAGNE, EE AARON MITCHELL, CPE DANIEL ZAPATA, EE
Summary Solar-powered remote-controlled vehicle with mobile device charging capabilities Consists of five (5) parts 1. Energy collection 2. Energy storage 3. Energy distribution 4. Interactive android application 5. Microprocessor
Goals Charge cell phones, tablets, and cameras outdoors Minimize reliance of electrical power via wall outlets Create a fun, innovative way to charge electronic devices using an alternative energy source
Objectives Energy collection Utilize solar panel to collect solar energy outdoors Energy storage Use battery to store collected energy Allows for charging in poorly lit conditions Energy distribution Split stored energy two (2) ways Powers microprocessor and mobile device simultaneously
Objectives Interactive Android application Touchscreen controls to move car forward, backward, and left to right Accelerometer controls to move the car Microprocessor Process signals from the application and run corresponding motor USB Powered directly from hub

Energy Storage +5V Fixed-Voltage Regulator 7805 Used to regulate output voltage of solar panel to +5V Ideal for use with input voltage requirements of power bank
Energy Storage Capabilities up to +5V at 1A Maximum Input Voltage: 35V DC Price: $1.99 (set of 10 units)
Energy Storage Vinsic Ultra Slim power bank Dual USB ports Ultra-slim design Aluminum alloy construction LED battery capacity indicator
Energy Storage Capacity: 2000mAh USB Port: 2 x USB Input: 5V, 2A Output 1: 5V, 2.1A Output 2: 5V, 1A Dimensions: 6.81 x 4.8 x 0.51 in Weight: 1.17 lb Price: $49.90
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
Microcontroller 5 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
Microcontroller We 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
