If I attached an LED to a serial port, could I turn the light on by sending constant 1s?
I know nearly nothing about serial programming…
I’ve got Arch Linux running. Would it be possible to write a constant stream of 1′s to keep an LED light going, if that light were connected to the serial port?
Of course it’s not designed to work with devices like that, but shouldn’t it still work? The LED should get the little pulse, and then that pulse will continue back to the computer. Who’s to know the difference between the LED and another computer?
1) The pulse doesn’t “continue back to the computer”. But that’s irrelevant.
2) The pin (a serial port has many pins you can use) is probably at about 10 volts. When you send a pulse it goes to -10 volts. Both are voltage to the LED and, assuming you have the proper current-limiting resistor, will light the LED. IOW, pin “on” or “off” (high or low) will light the LED. You’ll need an RS-232 to 5 volt level converter (+10 becomes 0, -12 becomes 5 volts) and about a 500-1k ohm resistor. And, on a PC, if you’re using the data out pin, you’ll have to tell the port that there’s a dataset connected to the port (by strapping a few pins).
3) If you just want to keep the LED lit (as in use it as a little flashlight), just connect it through a dropping resistor to a serial port pin.
4) That’s serial as in 9 pin or 25 pin. If you’re thinking of using a USB port, that’s a whole different ball of data.
