In this case, [Tod] wanted to use a momentary tactile switch to turn something on and off. Instead of going with a microcontroller he built the circuit around a 555 timer .

When the momentary push-button (PB) switch is closed, 12V from C3 is applied at A, causing T2 to turn on. This state grounds the Reset bus, turns on PFET T4 by putting V gs(on) on its gate through the ...

The timing interval of this timer is thus T=–1.1C 2 R 3 R 1 /R 2. Using appropriate values, you can obtain long time delays that you can't attain with the basic 555 circuit. But the real innovation ...

Inside a metal project box — grounded, of course — an ATtiny85 is connected to a button, an opto-isolated TRIAC AC power switch, and a ‘pilot’ light indicating power.

The new Trailblazer offers stable performance in urban and off-road environments. It features a system allowing drivers to switch between front-wheel and all-wheel drive modes with a button press.

The presence of the new C button has intrigued fans ever since it was revealed in Nintendo's original Switch 2 trailer, though GameChat has been met with a mixed pre-release response.

Switch 2 is available – Reviews are a long time coming The Switch 2 is available, as are its launch titles. However, interested parties still have to wait for reviews of the console and games.

Whatever you do, don’t press that button. It’s a trope that’s spanned pop culture for generations—and the real world, too. But where did this Big Red ...

My favorite smart switches are getting a useful upgrade (one they should’ve already had!).A new Auto-Off Timer in the Lutron app lets you set the switches to turn off a set amount of time after ...

If you press and hold down the Home button on the right Joy-Con, you can bring up a nifty Switch feature that's very helpful for quick tweaks and in TV mode.
