Literally the shittest fake OBD fuel saver yet

But obviously the cheapest microcontroller is still too expensive for the scammers, so they've reduced the circuitry to the minimum possible.
I say the minimum possible, but they could actually just have used a flashing LED and resistor, with the button shorting the LED for "user interaction".
