Introduction: Rotary Phone Dial + Arduino + Invisible Ink = Birthday Present
About: Retired Math teacher who needs a hobby! So I tinker with stuff: Arduino, welding, my 1958 TR-3 , my tennis serve
More About duboisvb »
I have a number of rotary dial phones and phone parts which I thought I could use in some silly way.
I starting with this instructable https://www.instructables.com/id/Interface-a-rotary-phone-dial-to-an-Arduino/
When I finished, I have a item which works as follows:
- dial any number or sequence of numbers
- press the big red button to test that sequence.
- the arduino will play a song based on the first digit of the sequence dialed.
- But if the correct sequence is dialed, in this case my daughters name, the arduino will play the "Happy Birthday song" , spin the metal screen and light the UV leds. This will reveal the "Happy Birthday message I wrote on the screen with the invisible ink pen.
video to follow
So basically what I have is:
The Arduino records the rotary phone input as a string and then the code checks for a particular string.
If it is not that string, it then plays one of 5 songs that are encoded in the sketch.
If it is the correct string then the arduino instructs the servo to turn and lights the UV lights and plays the birthday song.
The code follows:
I found pieces of it here and there. The tone function is used along with a pitches.h file.
/* 3/21/12 - started to make project with rotary dial
- to be used for birthday present for Christine
- idea:
dialing numbers will play a different song
dialing her name will light LEDs which will show the Happy birthday messgae
or the Happy aniversity for Harrie and Riek
- starting with the code for the batphonev1
- need to make many changes
-v2 - begin looking at watys to have many songs or notes
