i am using the following schematics for a NAND Gate. The two inputs of NAND Gate comes from output of two voltage comparators working in monoshot mode. on being triggered both the comparators give monoshot output for 10 seconds.
What i want is that only when both the comparators are on, the output of the NAND gate should be low and the led will not glow, otherwise the output will be high and LED will glow.
the gate is working fine, but with one problem. The ON time is getting Added...
What i mean is that if i trigger both the comparator at time t=0 seconds the output of both the comparators should be high for 10 seconds, hence the output of NAND Gate should be low for 10 seconds (LED IS OFF) and then go high again (LED glows),
the sequence is woking fine, except that the output of NAND Gate changes after t=20 seconds...can you please help?
