📌Problem Statement
-------------------------
I have a lot of trouble waking up early in the morning especially, guys when i work for you. Essentially this project allows you to open a relay at the time you set using the keypad and lcd. This relay can control many appliance from turning your tv or radio on to opening the window shutters in the morning. Lets begin !

-------------------------
📌 Circuit Design
-------------------------
If your wiring the relay to open shutters in the morning just open the switch housing and connect two wires between one in each terminal. Setting the time is very simple. First press the star key and enter the time you want it to go off then press the hash key to confirm. You can turn the alarm on and off using the hash key.
