I wanted to somehow improve the standard alarm clock, so I made one that wakes you up gently by only waking you up when you're not in your deep sleep. An added bonus is that It plays the Super Mario Theme Song as its alarm.
How it works:
It is more pleasant to wake up in the morning if you are not woken during your REM cycle of sleep.You tend to move around more when you're not in your REM cycle, so this alarm clock will only go off if a certain amount of motion is detected after a set alarm time. As a fail-safe, if the required amount of motion is not detected, the alarm will go off an hour after the set time.
Step 1: Materials
In order to create this clock, you'll need:
DS1307 I2C Real Time Clock Module+Board (SainSmart)
PIR Motion Sensor (Futurlec)
RGB LCD Shield with keypad (adafruit)
9V Wall Adapter Power Supply
Custom Shield (helpful for hooking up different elements to the Arduino in addition to the LCD shield)
Additional wires and boards for connecting components
