Dear Sir,
The PDF contains the circuit for device control and we have used the same circuit without any changes.The only addition we have done are the flyback diodes across each relay coil.
The issue we are facing is,when we try to turn on a "tube light" using a relay, more than one relay gets "clicked" and which in turn switches on more than one device.This happens only with tube lights(old pattern ones with choke and starter).When we tested the circuit with bulbs and CFLs ,the circuit performed properly.We have also tested our source program by attaching LED to the parallel port, and we are pretty much sure that there is nothing wrong in the bits being sent to the parallel port.Our circuit has also been tested separately,and the results are positive.
So what possibly might be the cause of this abnormal functioning of the relay when the tube lights are connected as the load instead of bulbs or CFLs?
Regards.
