Does anyone know of a way to hook up a thermistor or something up to the computer to measure or record the temperature in the room? Right now I am just trying to make something simple and cheap that I can hook up to the serial port, parallel port or USB port. It doesn’t matter where I hook it up as long as it is fairly easy for now Eventually I would like to make or buy a data logger so it would be more versatile and I could do other things with it. (When possible I like to make my own things because their usually less expensive, I can make it the way I want it and I can usually learn a lot from the experience). About 15 years ago with the help of a friend of mine at the time I made a circuit that I think used a 555 and a thermistor circuit that plugged into the joystick port of an old Atari computer. The computer counted the pulses which went faster or slower depending on the temperature. I don't remember much more than that. Right now I want to collect the data say every minute or 5 or 10 and send it to an excel spreadsheet or something to make a graph of what the temperature has been for the last day, week or month. Any help is appreciated.
Thanks,
Mike
