CONTROL ANY CIRCUIT WITH A TV REMOTE DSD PROJECT OVERVIEW

GROUP MEMBERS SARAH KHAN SAMIRA SIDDIQUA TASBIHA TABASSUM ANTORA

GOAL  Control multiple appliances and electronics using a single remote  An ordinary TV remote could be used

Arduino Microcontroller AC Power Adapter/Laptop 38 kHz Infrared Receiver Module Red LED Green LED Momentary Pushbutton Switch MATERIALS REQUIRED 100 ohm Resistors 5V Relay Modules BreadBoard Diodes

38 kHz Infrared Receiver Module detect the signal from the remote Red LEDWhen wrong password is entered, it light up Green LedWhen correct password is entered,it light up Arduinoserial monitor function to observe the value for the signals, password, And appliances observation. It is also where interfacing is done and program are stored. RelayActs as a switch. And also arduino wont work on bigger appliances, and we use relay for bigger voltage supply. DiodeTo prevent damage to relay. COMPONENTS

PROCESS Devices are interfaced and switched using different keys of the remote ARDUINO Microcontroll er is used to control the inputs and outputs. Infrared receiver is used to receive the infrared signals from TV Remote.

MAIN IDEA Hardware:  Receiver detect the signal from the Remote  Different button have different values  The signal value from each button are recorded.  The necessary signal value are taken and programmed.  Allocated different signal values for each of the outputs(appliances) uniquely.

MAIN IDEA Software PasswordIRemoteServo password.ap pend(number ); password.res et(); password.ev aluate() irrecv.enableI RIn(); irrecv.decode (&results); irrecv.resume (); myservo.atta ch(9); myservo.writ e(angle);

password.append(number);Append a character to the currently guessed password password.reset();Reset the currently guessed password password.evaluate()Is the guessed password equal to the target password? irrecv.enableIRIn();Start the reciever irrecv.decode(&results)Deoode the signal and turn it to value irrecv.resume();Ready to receive the next signal myservo.attach(9);Servo input myservo.write(angle);Move the servo to the specified angle

BUILDING THE CIRCUIT

DIFFICULTIES  Servo: Figuring out which angle work best  Signals from different remote was detected

RECOVER Servo: Trial And Error Reciever: Coding the button as much as possible. Isolated Case.

BENEFITS  Convenient  Cheap  Weak body people  Patient  Handicapped  Tired people

Future Development  Screen System for display  Better security related(Password)  Android System  Bigger appliances
