Hello Everyone,
i have circuit with two ICs , AND Gate and a 555 Timer
The output of the AND GATE IC is the input Voltage of 555 Timer
i am using timer to blink the LED connected at the pin '3',
Here is the circuit ,
AND gate IC 14 pin is connected to VCC and 7 pin to Ground,
since the input voltage of Timer is the Output of AND GATE ic ,
what should be the ground of Timer ???
I so confused
when i am connecting Timer ground to the Same ground as AND Gate ic then the LED connected at the output terminal of Timer is not blinking it is remain in 'ON' state.
