Fig. 1: Debounce circuit When the switch is closed, the capacitor starts discharging through Rd, and hence the voltage output (Vout) becomes high. In the bouncing condition, thecapacitorstops the voltage at the input voltage (Vin) until it reaches Vcc or ground, preventing false triggering. ...
Working of the Hardware Debounce Circuit The circuit is consists of twoNand gates(74HC00 IC) forming aSR flip flop. As you can see in the circuit diagram whenever the toggle switches to the A side the output logic gets ‘HIGH’. Here, we have used an oscilloscope to detect ...

At this point, an electrical circuit specific to the enter key is closed (either directly or capacitively). This allows a small amount of current to flow into the logic circuitry of the keyboard, which scans the state of each key switch, debounces the electrical noise of the rapid ...

A Schmitt trigger is a comparator circuit that makes use of positive feedback to implement hysteresis and is used to remove noise from an analog signal while converting it to a digital one.
and it's a big (small) resistor...anyway with relay open what's your dc path to gnd? There is no path to ground in the original circuit with the relay open either, what's your point? Logged Shaydzmi Regular Contributor Posts: 117 Country: Re: What do I need to get this optocoup...

debounces the electrical noise of the rapid intermittent closure of the switch, and converts it to a keycode integer, in this case 13. The keyboard controller then encodes the keycode for transport to the computer. This is now almost universally over a Universal Serial Bus (USB) or Bluetooth...
To pick a zero point, let's choose the Enter key on the keyboard hitting the bottom of its range. At this point, an electrical circuit specific to the enter key is closed (either directly or capacitively). This allows a small amount of current to flow into the logic circuitry of the ...
