This device notifies the user of alerts via high intensity flashing lights and through the use of a shaker. The device is controlled by the user wirelessly via Bluetooth through a handheld device such as a cell phone. Functional Overview: • Customer Needs: • Small and lightweight for travel • Flashing high intensity LEDs • Bed shaker adapter • Rechargeable batteries • LCD display to view time and notifications • Low battery indication LED • Bluetooth to communicate to Android® devices • Receives notifications of text messages and emails. • Mobile Application to set/cancel alarms and control High Intensity LED and shaker. • User friendly • Physical alarm turn off on physical device • On/Off switch for travel • Durable housing design BlueGiga ® WT12 UART Android ® Device GPIO Bed Shaker GPIO LCD Display Raspberry Pi ® GPIO Alert LED’s 12V DC Power Supply Electrical Overview: PCB Layout: 12 V Li-Ion Battery Charge Controller 6 - 12 V 8.2- 6 V 5 V On/Off Indication Circuit Warning LED 6 - 12 V 5V Regulator TX/RX Screen Out 5 V 12 V LCD Screen 5 V Raspberry Pi 3.3 V 5 V Bluetooth WT12 Mobile Application Interface: 3.3 V Alarm Off 3.3 V 3.3 V Shaker On/Off On/Off Shaker Switch High Intensity LEDs Switch High Intensity LEDs Software Overview: Thermal Analysis: LCDDriver.py +begin(in cols : int, in rows : int) +home() +clear() +setCursor(in col : int, in row : int) +autoscroll() -write4bits(in bits : byte, in char_mode : bool = False) +pulseEnable() +message(in text : string) Case Design: • Results: • Fully functional alarm clock with bed shaker and high intensity LEDs. • Able to communicate with Android ® mobile devices via Bluetooth to receive emails and text messages which can be displayed on the device’s LCD screen. • User friendly mobile application that controls enabling/disabling alarms, high intensity LED flashing patterns, and bed shaker shaking intensities.
