Arduino Nano Digital Alarm Clock With LCD and Buzze
To make a simple digital alarm clock using an Arduino Nano, 16×2 LCD, two push buttons, and a buzzer.
Supplies
DESHBOT SHIED
Arduino Nano
Lcd 16 x 2
Buzzer (inbuild)
Button (inbuild)
WORKING
The Arduino Nano keeps track of the current time and displays it on the 16×2 LCD. The D12 button is used to enter and set the alarm hour and minute. The D10 button increases the selected value and stops the buzzer when the alarm rings.
When the current time matches the programmed alarm time, the buzzer connected to D11 starts beeping. Pressing the D10 button stops the alarm.
