Twitter Enabled Text to Speech. Let the world know what you're eating for breakfast with an 80's style vocal synthesizer!
This project uses an Arduino to send your Twitter stream to a voice generator chip called the SpeakJet. The setup that I use here can also be extended to other applications where you'd want to translate text into speech, some ideas: -a robot which announces things or responds to its environment by speaking -some kind of assitive technology for the deaf or handicapped -at the very least, it's a fun alternative to using the serial monitor to print data from the Arduino In this setup the Arduino requests and receives information from Twitter via an Ethernet shield, which is directly plugged into a router (the USB connection shown in the picture is being used solely for power, not data transmission). An intermediary chip called the TTS256 translates serial text data from the Arduino into a series of allophones to send to the SpeakJet. A demo of the SpeakJet's voice can be found here.
Parts List: How to make a remote-control sentient web-puppet by hacking Twitter, Google, Skype, Arduino and Processing! How to manipulate a physical object over the web just by using common web services and their accessible data feeds, with some added open source stuff to decode and manipulate that data, and ultimately use the data to move and control physical hardware.
Twitr_janus - a prototype web-controlled puppet This Instructable describes Twitr_janus - a puppet I made to see if it was possible to mash up free digital web services (Twitter, Google Spreadsheets and forms, Netvibes and Skype) with open source hardware and code (Arduino language and environment, Processing and related Processing libraries) and use them to manipulate an object over the web. It turned out it was indeed possible! See how Twitr_janus works and see how you can use these ideas to build your own remotely-controlled physical objects. It was built from cheap, easily available stuff, some of it salvaged. Here's Twitr_janus in action, describing itself and how it works... Summary of what it can do... The puppet can: Arduino - Control DC Motor via Bluetooth. * created by Rui Santos, * Control DC motor with Smartphone via bluetooth int motorPin1 = 3; // pin 2 on L293D IC int motorPin2 = 4; // pin 7 on L293D IC int enablePin = 5; // pin 1 on L293D IC int state; int flag=0; //makes sure that the serial only prints once the state void setup() { // sets the pins as outputs: pinMode(motorPin1, OUTPUT); pinMode(motorPin2, OUTPUT); pinMode(enablePin, OUTPUT); // sets enablePin high so that motor can turn on: digitalWrite(enablePin, HIGH); // initialize serial communication at 9600 bits per second: Serial.begin(9600); void loop() { //if some date is sent, reads it and saves in state if(Serial.available() > 0){ state = Serial.read(); flag=0;
