Greetings.
I have a simple 555 astable circuit with a 16 seconds Mark (HIGH) and a 0.3 seconds Space (LOW): Pic.
I want to reset the circuit every time I feel like resetting it. This means that every time I press a button or send an electric signal, I want the 16 second HIGH countdown to go back to 0 and start again.
This means that if the output has been HIGH for 10 seconds and I press the button, the output will be LOW in 16 seconds and, when that happens, I can say that the output was HIGH for 26 seconds.
According to the first image in this page, the way this can be done is by fully discharging the timing capacitor (C1 in that page's image and C2 in the image I linked to above).
Using the Reset pin makes the output go LOW, which is definitely not what I want.
So here is my question: how do I discharge that capacitor?
Will this work (the point is: I send a 5V signal from an Arduino, or something else)?
I am effectively short-circuiting the capacitor - is it... well... bad?
Thank you!
