lazy Man Remote

The arduino based IR remote glove for TV is a very simple remote that can be built in less than one hour, it only require simple passive electronic components beside the arduino itself this idea came to mind while I was playing around with the IR_REMOTE library.

The most unusual thing is the key scan method, I derive the key inputs from a 4Bit Bus because it offer more possible keys than an equal number traditional Pin-per-pin key arrangement. It require pull-Down resistors to make sure the bus is return 0 when there is no valid key press.

The arduino is powered via a USB cable conected to a powerbank.

Note this project is far from perfect and is only for experimenting purpose and my note work for you since is for the TELEFUNKEN TLEDD-32FHDB TV.

Findig the Key Codes

since most part of our IR remotes dont have any details aboute there codes and comunication protocols we have to do the djob our self read the instructables in the link bellow to guide you.

Solder All the Components to Arduino

Solder the 4 wires to the 1k resistors then solder the resisters to arduino From D4 to D7 to create a pull-down voltage to prevent unintentional key presses and one wire to the arduino 5V.

Solder the IR out wire to arduino D3 and solder it to IR LED positive terminal, and the IR LED negative terminal to arduino GND, “I haven’t use a current limiting resistor because it make the IR LED useless ”.

Make the Touch Pads

The touch pads are made using fine copper wires wrapped around the finger of the glove

Join Everything Together

While wirering everything together make sure that D0 is ate the most left finger and D3 is ate the right and the remaining finer is the touch VCC (+5V/3.3V).
