How can I read the I/O bit on a RS232c PC serial interface to light LEDs? Answered
I'm building a circuit to read bits from a RS232c PC serial interface and command LEDs groups, a bit a group. Bits are sent by a PHP code written on a site to accessed anywhere. The circuit board must then be plugged on the laptop at place where the LEDs are installed. Please, can anyone help me on building this project? I appreciate any help.
