Hacking a TV with Arduino uno

how to build an Arduino TV annoyer

Most of those projects are aimed toward network hacking and data gathering, like every good hacking project, however this one, the DIY Arduino-based TV annoyer, is strictly for fun and laughs. Put simply, this small device canactivate TVs when you want them off, and switch TVs off once you want them on. think about it as an easy aprilFool’s gag, or something a bit more innocuous and less aggravating than the always-classic annoy-a-tron from ThinkGeek.

Arduino fans, this project turns TVs on once you need them off. It makes an ideal April Fools’ Day joke or gag gift—or, within the spirit of Evil Week, use it anytime of year to drive folks crazy. you can hide it in something unnoticeable, and assuming you have already got an Arduino and tools, it prices less than $1.50 to make.

Step One: What we need:

1x Infrared Detector ($0.78) http://goo.gl/6sSN6

1x Wide angle Infrared led ($0.23) http://goo.gl/5PFlS

Some wire (preferably solid-core, twenty two gauge or so) (About $7-$8 at your local hardware/electronics store)
Tools1x USB A-B cable (for programming the Arduino) ($2.95) http://goo.gl/3f6rx

1x soldering iron (Optional) (About $15-$25 at your local hardware/electronics store)

1x Spool of thin solder (About $10 at your local hardware/electronics store)

1x Arduino IDE (can be downloaded here)

1x 10 Ohm resistance (Brown, Black, Black, Gold) ($0.05) http://goo.gl/UiKDs

1x USB A-B cable (for programming the Arduino) ($2.95) http://goo.gl/3f6rx1x 47 Ohm resistor (Yellow, Purple, Black, Gold) ($0.10) http://goo.gl/89jXQ

1x Arduino Uno (or equivalent) ($25.00) http://goo.gl/p9wVs

1x narrow angle Infrared led ($0.23) http://goo.gl/67sCf

1x 2N3904 PNP electronic transistor (or equivalent) ($0.08) http://goo.gl/XD3jI

1x Solderless breadboard (About $5-$6 at your local electronics store)

1x laptop (I would hope you know where to get one of these)1x 10 Ohm resistance (Brown, Black, Black, Gold) ($0.05) http://goo.gl/UiKDs

1x 47 Ohm resistor (Yellow, Purple, Black, Gold) ($0.10) http://goo.gl/89jXQ

Step Two: Wiring

Time to assemble! I did this on a solderless board.
1. connect IR Detector. ensure the dome on it is facing you.
2. Connect the left pin of the detector to Arduino Digital pin 2, the center pin to Ground, and also the right pin to +3.3V.
3. connect the 2N3904 NPN electronic transistor. ensure the flat aspect is facing you.
4. Connect the left pin of the electronic transistor to the forty seven Ohm resistance, the center pin through the tenOhm resistance to Arduino Digital pin three (PWM), and also the right pin to Ground.
5. Connect the cathodes (negative, features a shorter leg, and also the aspect is marked with a flat half to point the cathode) to the other end of the forty seven Ohm resistance, and also the anodes (longer lead, not the cathode) to +3.3V.

Step Three: transfer the Sketch

Now for the programming. Connect your Arduino to the pc using the USB A-B cable, then transfer the .ZIP file. In the .ZIP file, there ought to be a folder known as “TV_Annoyer.” Copy this folder into your Arduino volume folder. On a Windows machine this can be sometimes placed in “C:\Users\\Documents\Arduino.”

Open the sketch within the Arduino IDE (downloaded from the Arduino.cc website), and transfer it to the Arduino board. If it does not transfer right, strive these troubleshooting tips:

1. Restart the Arduino IDE.
2. try unplugging/replugging the Arduino into the pc.
3. ensure that your Arduino is correctly connected to your pc.
4. Check if your correct board is chosen within the “Tools>Board” menu at the highest of the IDE.
5. ensure the correct COM port is chosen within the “Tools>Port” menu at the highest of the IDE. you’ll check thatCOM port your Arduino is on by (on a Windows machine) clicking the “Start” button, and sorting out “Device Manager”. Then click the arrow next to the “Ports (COM & LPT)” choice. Your Arduino board ought to get on that list, next to the COM port it’s connected to.

Step 4: Use It!

After you have successfully connected everything and uploaded the sketch to the Arduino, it’s ready to be used! check it out by putting it close to your TV, plugging it in to a power supply, and clicking the TV’s remote. ensure that the IR LEDs are pointing at the TV and also the dome on the IR Detector is facing towards the remote.
