Hi
I am building a light sensor project which i have designed. I am measuring ambient light using LDR and passing it to my computer using Parallel port. then i am defining some preset voltages in the CPU, which i will compare with the LDR output. The difference of this is what i want to give to the LED Lamp through serial port. But i am not getting the right way to do it.
Can anyone give me the idea to of how to connect the serial port to the LED lamp???
I am doing C programming in linux for this project.
Help as soon as possible will be appreciated!!!
Thanks,
