i have made a simple circuit to switch on/off devices using relay, but I am unable to send a signal from computer to the device.
As i am on WIndows XP, i cannot use a simple function of C outportb(), they winXP wont allow, and certainly it does not
well then i tried connection USB wire to the circuit and it works the same as parallel port, i mean it also gives +5v. I just want a simple program which can send +5v and 0 to the USB or parallel port, but with XP i am unable to do that
Is there a way out ? i mean with C# or C++, while i was googling i found a DLL "inpout32.dll" and a sample code, but it doesnt seem to be working.
just give me advice, no matter whatever language it is, may be its java,python,perl.. but do it..thanks
Please help me.. thanks a lot
thanks for ur time
