Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I ...

This push-button fan switch design includes a timed automatic shut off, connections to the mains, and other minor changes from previous Design Ideas. ... The circuit mounts in the switch wall box in ...

After I proposed: PIC reset and I/O on the same push-button? K Wittingham responded: "Why not use a D-Flip Flop Switch connected to clock and via an RC to the Data input. Release switch quickly data ...

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 .

In this design, the output is connected to the input of the gadget when you press the push button (PB) once. For the next push, the output is disconnected. Wow the engineering world with your unique ...

The switch circuit consists of two transistors, a comparator, a flip flop and a monostable. As you might expect, the button triggers the flip flops to turn the triac on.
