Hello all!
I want to control multiple Relays from a PC and get the values from various sensors (temperature and humidity). But my skills in electronics are low, so anyone can help me to design a smalll circuit to interact with the relays and with the sensors from any port of the pc please?
I did a research in internet and i found the pinouts of the parallel port and the pinouts of the serial port and various schematics but i don't know if they are what i need. Here is what i found:
**broken link removed**
This is for the relays i think, is it ok? zero resistors?
I want to use about 5-6 sensors (humidity and temperature). I looked in Digikey.com but i don't know which one is the best for my use, and or the easy ones to conect to the serial or parallel port. Any suggestions here please?
Thanks!
P.D. Sorry for my english! I'm still learning.
