Introduction: Arduino PHP Text and Data to Speech - an Automatic Weatherman
In my continuing efforts to stay one step ahead of the forthcoming ai apocalypse, I have started teaching machines to speak in a human-ish voice so that we can all be future friends together. Here, I'm going to show how text and data can be woven together to produce audio 'sound bytes' for broadcast on a loudspeaker.
Think about it like this - imagine an automated weather man who might replace the one on the radio. He has all the data right at his finger tips - all we got to do is make him sound human. Our data is coming from a real weather station that updates every ten minutes onto the internet.
This is a deceptively easy and fun project and the Arduino hardware is very simple to set up - essentially just an Adafruit Fona Feather and an Emic text to speech module. I'm using a GPRS Fona module, but this could be replaced with a wifi version, but with different code (not so easy).
But what on earth is PHP? ..... I've no idea what is stands for, but basically it's a special language and protocol that can manipulate data and spit out very simple and useful information in easy to read formats. In this case, the PHP webpage displays an extremely simple long line of text (see video) that is picked up by the Feather module and fed into the Emic down a serial bus. If we tried to use an HTML webpage the readout would include all the HTML background code and not just what you'd see on a website - PHP conveniently hides all it's internal 'working' code from being published.
If you want to see the actual PHP readout with the text and data intermingled, click here:

and if you cant be bothered to create your own PHP file (which can be rather tricky) - just use mine at the above address.
Special thanks to a kindly fellow called shamyl who hacked the Emic2 Arduino library and created a hardware serial compatible version:

Step 2: PHP Code
Here is an example of what the PHP code might look like. Looking at the block of text that starts with "hello my friend", it's essential that there are no large gaps between the words. The '..' is used to create pauses. Tabs must never be used!
The actual data is retrieved from a database with commands such as:
<? echo $hourminutes; ?>
and woven into text as shown below, with passwords etc. as XXXXXXXXXXXXXXX:
<?php
// this refreshes current page after 2 seconds.
header( "refresh:2;" );
include ("getid.php");
$host="localhost"; // Host name
$username="XXXXXXXXXXXXXX"; // Mysql username
$password="XXXXXXXXXXXXXX"; // Mysql password
$db_name="XXXXXXXXXXXXXXX"; // Database name
$tbl_name="XXXXXXXXXXXXXXX"; // Table name
// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
// Retrieve data from database
$sql2="SELECT * FROM XXXXXXXXXXXXXXX ORDER BY id DESC LIMIT 1";
$result2=mysql_query($sql2);
?><?php
// Start looping rows in mysql database.
while($rows=mysql_fetch_array($result2)){
?>Hello my friend .. how are you doing? .. Here is a quick run down of the weather outside .. the current reading eye dee is <? echo $rows['id']; ?> .. and the last reading was on <? echo $day; ?>
.. at <? echo $hourminutes; ?> hours .. the windpseed was <? echo $rows['windspeed']; ?> knots .. with a maximum gust of <? echo $rows['windgust']; ?> knots .. and the wind direction was <? echo $rows['windway']; ?> .. degrees .. The outside temperature was <? echo $rows['tempout']; ?> .. degrees celcius. .. The battery volts was <? echo $rows['volts']; ?> .. volts. .. and the humidity was at <? echo $rows['humidity']; ?> .. per cent .. Thankyou for listening .. and have a nice day .. oh .. one last thing ..please dont forget to vote for this instructable in the make noise competition.
<?php
// close while loop
}
?><?php
// close MySQL connection
mysql_close();
?>

Step 4: Singing Weather Man
The emic2 can also be programmed to sing songs. I revamped the layout using a MEGA2560, Adafruit SIM800L Fona shield and a DS3231 real time clock (RTC) using the code below to get it singing. The first 12 lines of code shows how to connect the gadgets:
WARNING: The singing weather man is rather silly and may offend persons of a more serious nature. He's also very patriotic!
Singing is achieved using something called the 'DecTalk parser' and 'Phonemes' and using this example code and the datasheet attached, you can produce your own little ditties! The crucial example piece of code is here, which sings "God bless America":
emicSerial.println("P0");
emicSerial.println("S [:phone arpa speak on][:rate 190][:n0][ GAA<400,12>DD<200,15>B<200,10>LLEH<200,19>EH<500,22>S<200,18>AH<100,18>MEH<200,16>K<100,13>AH<200,12>][:n0]");
emicSerial.print('\n');
And here's the code in it's entirety:
#define rxPin 11 // Serial input (connects to Emic 2's SOUT pin)
#define txPin 12 // Serial output (connects to Emic 2's SIN pin)
