Assignment
Build a prototype Arduino UNO-based alarm clock, which should also display temperature and humidity values. It will be a standalone gadget powered by a 9 volt battery or AC adapter. A connection to the computer will only be required to update the firmware. Time information will remain saved even if the external power becomes unavailable.
All the components and modules required to build it are available in the kit. Only the 9V battery (holder is part of the kit) or an AC adapter will be required to be purchased for the final demonstration and continued standalone use.
The following modules and components will be used:
• Arduino UNO board
• 1602 LCD display
• DS3231 I2C real time clock
• DHT11 temperature and humidity sensor
• Piezo buzzer
• 9V battery connector and jack
• LEDs, pushbuttons, resistors, wires, and so forth, as required
Required features:
• Ongoing display of time, temperature, and humidity
• Date, month, year, and day of week, on demand
• Setting or editing time and date
• Setting of an alarm.
