1. Team #5 - HotJac Problem Hardware Design Software Design Results
Having come from temperate climates, our team was trying to solve the problem of layering or wearing bulky uncomfortable clothes during the winter.
There are already available options for this problem, but these solutions aren't affordable.
Our team is looking to create an optimal design that combines quality and affordability to provide heat and comfort to the average person during the long dreary winter days.
Overall Design
The hardware design composed of heating pads, a temperature sensor, an H-Bridge, HC-05 Bluetooth Module, an Arduino Uno and a battery.
Each of the components were picked from research and testing, and the arrows above show the connectivity path.
Design Description
The Arduino is used as a microcontroller to monitor the system.
The H-Bridge uses PWM to control and vary the temperature of the heating pads
The HC-05 is a Bluetooth 2.0 module that helps connect the system to the Android Application.
The Heating pads heat up from about 90 ºF to 140 ºF.
The rechargeable battery which would supply about 12V would power the Arduino and to the H- Bridge.
UI Design
The software design comprises android and arduino code. They run on a Samsung Galaxy S7 and Arduino Uno.
Functionality
The android app is used to control the heating pads’ power delivery and read the battery and temperature sensors continuously. It is also contains and instruction fragment which explains how to use the app itself.
Details
Android v23 with API from Google is used to obtain weather data.
Arduino and bluetooth libraries in android studio are used to allow connectivity
Arduino IDE with HC05 libraries are used to allow handshaking and configuration of the PWM
