Digital Wall Clock with Temperature Sensor using Arduino Kit Android Project – SRS Document

Digital Wall Clock with Temperature Sensor using Arduino Kit Android Project – SRS Document.

Project Domain / Category:

Digital Logic Designing / Embedded System Programming

Abstract / Introduction:

A digital clock is a type of clock that displays the time digitally (i.e. in numerals or other symbols), as opposed to an analog clock. To represent the time, most digital clocks use 7-segment displays.

As the name indicates, each 7-segment display consists of seven LEDs (segment). Each segment is independent and when illuminated as a group with other 7-segment displays, forms part of a numerical digit (both Decimal and Hex) to be displayed.

In this project, we are going to design a digital wall clock using 7-segment displays to represent time as well as the room temperature.

However, to display the digit, we will be designing each of the 7-segment display my own instead of taking the industry manufactured 7-segment displays

Functional Requirements:

  • The clock will display the current time in HH: MM AM/PM format.
  • The clock must be able to display time in any format (12-hour or 24-hour format). To change the displayed time format, a toggle button will be used.
  • The clock will display the room temperature in either Celsius (⁰c) and Fahrenheit (⁰F) scale. To change the temperature display format, a toggle button will be used.
  • The clock will be equipped with a numeric keypad and control buttons to allow the user to change/update time.
  • This will be a DC-powered digital wall clock which will be operated using a rechargeable battery and a DC charger.

Tools and Equipment:

  • Any Microcontrollers OR Arduino kit
  • C/C++ Programming Language
  • Assembly Language
  • Circuit Designing Software’s (OrCAD Spice, Workbench)
  • Keil Embedded Development Kit
  • Microcontroller Burner Kit
  • Circuit Components (LEDs, Resistors, Capacitors, oscillators, etc.)
  • Temperature Sensor
  • Rechargeable battery, Charging adapter

Important Instructions:

  • This project requires deep knowledge related to Digital Logic Designing, Circuit theory, and Microcontroller programming. Without these skills, you will not be able to complete this project successfully.
  • The project must be provided in the presentable form.
  • The project must be designed by the student himself/herself.
  • In case of any customization desired by the user in the project, the student must consult the supervisor first to seek permission.
