Morning Alarm
Intro: Morning Alarm
This alarm will wake you up if light from sunrise gets into the LDR but this works best in the summer.
STEP 1: Building the Circuit
Ldr->5v
Ldr second pin-> resistor
Resistor and ldr connection->a0
resistor second pin->GND
STEP 2: Getting a Speaker
You can use a soaker from a toy, almost any speaker will work just hook it up to pin 13 and ground but if this doesn't work try pin 12.
STEP 3: Programming It
Here's the code.
