hi,
i have an idea for a project to control a circuit with a serial port but i need some pointers on how to actually make the circuit i need.
i am completely new to circuit design but i have a [very] rough knowledge of how it works.
basically, i want 6 solenoids, and to be able to turn them on/off in any combination using a standard pc serial port.
as i said, im completely new to this, but as far as i can guess, what i want to do is going to be similar to bit encoding, except physically. i understand that it could be done by varying a current, and that current being reisisted/let through at different levels to activate different parts of the circuit. but thats about as far as i got before realising i had no idea how to do it
any help and information would be much appreciated.
