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. What he really needed in ...

The electronic analogue of the push–button switcher uses bistable elements (Figure 1), which are turned on by applying a high-level voltage to the input of the element and turned off by applying a low ...

Push the switch and T2, a BS170 NFET ... R1, R2, R6, and C3 form an RC time delay circuit that protects against switch bounce. OUT-14 of the 4060 goes high after 27 minutes and turns on T3, which ...

I am trying to design a little circuit to control a light. I am trying to design a little circuit to control a light. It is supposed to be a one-push-button affair, with a long push for something and ...

[Ed] was tasked with adding push-button degaussing to an arcade cabinet ... power supply decoupling cap to power the new deguassing circuit and connected the SSR to the Arduino as an open ...
