How many times do you need to set your alarm clock before you actually climb out of bed in the morning?
We all have a tendency to check an alarm clocks setting at bed time to make sure it is set right. This clock is almost similar to the one the author previously made, instead of using MSP430 but PIC24. RTCC pheripheral was used for timekeeping while LifePO4 battery as the source of power supply that is charged using USB charger. He also used photo transistor to dim the display in the dark.
As always the author is kind enough to include the source code for us to understand how the project runs. You can also watch the video which walks us through the process. For the display, he used a 7 segment display included with MOSFET placed under it. This bedside alarm clock has what you’d expect from an alarm clock.
