Firmly say "Time" and this bird will count the hours by bobbing forward and the minutes (in multiples of five) by bobbing backward. He does a little "wobble" between hours and minutes so that you will know, "the times, they are a changing."

Step 1:

An Arduino "listens" for sounds and operates a servo motor to display the time.

Major materials needed:

Arduino Radio Shack
small servo motor amazon.com
drinking bird amazon.com
acrylic butter dish homeandwine.com
breadboard jameco.com
2n2222a jameco.com
2 microfarad capacitor jameco.com
9 volt dc power supply jameco.com
microphone jameco.com

Step 2:

Above is an abbreviated flow diagram for the software.

Software:

#include <Servo.h>

int ledPin = 13;
int minute=0;
int hour=7; //start time at 7
int valm=0;
int valm1=0;

Servo myservo;

static unsigned long lastTick = 0; // set up a local variable to hold the last time we moved forward five minutes
// move forward five minutes every 300000 milliseconds

void setup() { //set outputs and inputs
myservo.attach(5);
pinMode(ledPin, OUTPUT);

}

void loop() {

if (millis() - lastTick >= 300000) {
lastTick = millis();
minute++;

}

// move forward one hour every 12 five minute intervals
if (minute >=12) {
hour++;
minute = 0; // reset minutes to zero
}

if (hour >=13) {
hour=1;
minute = 0; // reset minutes to zero
}
valm=analogRead(0);
if(valm>400){
   delay (10);
   valm=analogRead(0);
   if(valm>300){

}

Step 3:

Wire up the microphone assembly on the breadboard.

Step 4:

Separate the drinking bird from his legs. Drill a couple of holes on one side of the leg assembly and glue the servo motor (I used Gorilla glue) to the legs.

Step 5:

Drill a hole in one side of the bird's "axle."

Step 6:

Drill a hole in the servo arm.

Step 7:

Fasten the servo arm to the bird with a screw.

Step 8:

Twist the bird "axle/servo arm" assembly and screw the arm into the servo motor.

Step 9:

Twist the bird/arm into its final position. Tape the end of the arm to secure it and prevent slippage. I used aluminum duct tape.

Step 10:

Connect the Arduino to your computer and upload the software.

Place double sided tape on the Arduino and breadboards. Stick them to the butter dish.

Step 11:

Cut the end off the cable that comes from the servo motor (red, black, white).

Step 12:

Solder one end of a jumper wire to each end of the servo cable.

Step 13:

Plug all the wires into place.

Step 14:

Plug the clock in--it will default to seven o'clock.

Each press of the red button will advance the clock five minutes. If the time is 8:15, press the red button 15 times.

You may want to stop occasionally and say "Time" to the bird--making sure you don't overshoot your target time.

That's it--enjoy!
