WRONGCO Wake 'N Shower Travel Alarm Clock

Rube Goldberg style alarm clock system,The entire system is powered from a 12V battery and a 100W inverter. There is a solar panel for recharge.

while the alarm clock radio is ON or Wake to Music, radio stations play as normal, with a light organ providing visual entertainment

HOWEVER 

the alarm setting gives a 10 second (or more) cold shower to the sleeper when the alarm goes off.

The light organ is Arduino based and MSGEQ7 control .

The light organ software is updated (from its orginal 2015 program) to detect the alarm audio signature and then turns on a relay to drive the sizable 11 gallons/minute aquarium pump.

You Gotta watch the hilarious video:

  EqiilizerLEDsWakeNshower

  is started from EquilizerLEDsRev1_Working is  EquilizerLEDsRev0_Working with bands 1 and 7 with lower thresholds

  EquilizerLEDsRev0_Working is a relabled version of Test 3 Working, based on Test2Working

  showing the MSWGEQ7 is reading an analog input from a ipod earphone jack, and providing volts from the multiplexor.

  -> added pot to analog input 1 for threshold adjust on LED trigger

  -> add a PB to D6 to run a test routine that strobes the lights

  -> add ULN2803 driver for LEDS, requires to un-invert the HIGH LOW states

  control interface to MSGEQ7 IC

  strobe control for equalizer bands, read in multiplexed voltage per band, drive outputs LEDs

  Arduino D4 wires to MSGEQ7 pin 4 strobe

  Arduino D5 wires to MSGEQ7 pin 7 reset

  all ins have pull ups

  Arduino D7 = 63Hz LED , LOW = ON

  Arduino D8 = 160Hz LED

  Arduino D9 = 400Hz LED

  Arduino D10 = 1kHz LED

  Arduino D11 = 2.5 kHz LED

  Arduino D12 = 6kHz LED

  Arduino D13 = 16kHz LED

  Arduino A0 wires to MSGEQ7 pin 3 Vout

The WakeNShower audio input comes from an alarm clock, tapped from its speaker thru an audio transformer.

The code adds a relay output to D3.

The alarm sound is a loud 1kHz square wave that triggers D10 thru D13.

Use those signals to determine if the alarm sounded, and to pick up the relay.

The relay activates a water pump for the shower.
