README
README.mdGesture Based Media controller
What is it
It's a device that controls your TV using IR signals to mimic your TV's remote control. It detects a gesture and then sends the signal that was coded for that gesture.
The reason I made it
I made it so I can control different media without having to touch anything with my dirty hands while eating.
Main modules used
- MCU: An ESP32
- Gesture Sensor: PAJ7620
- Display: OLED 0.96" SSD1306 Display
Pins and their usages
- GPIO4: IR LED
- GPIO15: IR receiver (TL1838)
- GPIO21: SDA (for both the Gesture Sensor and the display)
- GPIO22: SCL (for both the Gesture Sensor and the display)
- GPIO18: delete button (Internally pulled high)
How to recreate
You can either make the PCB with is here or connect everything on a breadboard (while using this as a reference) then you can flash the software provided here to your ESP32.
Gestures and their functions
- Move Up / Move Down:
Up Button / Down Button - Move Left / Move Right:
Left Button / Right Button - Move Forward:
OK button (for TV) - Circle Clockwise (CW) / Circle Counter-Clockwise (CCW):
Volume Up Button / Volume Down Button - Wave (shake):
switch between different TV/PC (Inoperative for now, PC functions will be available in V2)

Notes
- Please note that AI was used to help with some parts of the code and not all of it.
- This is the first version of this project and it doesn't have all of the functions. V2 will have battery percentage measurement, better UI, and will be compatible with both TV and PC with the ability to switch between them.

Questions
How big is the Media Controller PCB?
It measures 32 × 130 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Media Controller use?
34 parts, built around the MCP73831T-2ACI/OT-HXY, MIC5219-3.3YM5, SZYY0603Y and AO3401. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Media Controller KiCad files?
From the mkhairyx/Media_Controller repository on GitHub, at the commit this page was made from: the board is Source/KiCad/Media_Controller/Media_Controller.kicad_pcb and its schematic Source/KiCad/Media_Controller/Media_Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Media Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask mkhairyx before reusing the design.
