I would like to read the signal from a sensor periodically, for example 0.5Hz, but my circuit does not have a microcontroller.
Firstly, I think that if I can implement a timer, like a 555timer, with some logic gates to read the signal from the sensor. However, when the timer is not enabling to read the sensor signal, the output of the circuit should be latch. I do not know how to implement this.
The truth table:
Or is there other simpler method?
Thank you very much.
