Wow Eric, that's awesome :D. I'm going to study this diagram and i will make another one with a decoder and latchs to learn, i will post the result here. Which software for simulating will you use to do this?
P.D. Send me the visual basic code if you want i will learn from it, but the program...
Yes i write in Visual Basic. But eric, which sensor are you using with the MCP3204? And another important question, can i use the SAME parallel port to control the relays and input the values of the sensors to PC?
Thank you!
Thank you Ericgibbs, the small program that you post works very well.
Now the problem are the sensors, i am totally lost here, i don't understand at all the MCP3204 and MCP3208 usage. Which type of sensor output i need?? I can see the cheap ones output "capacitance value" and the more...
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...
