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 a short push for something else. One crucial thing is, that ...

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.

K. Whittingham’s cunning push button circuit After I proposed: PIC reset and I/O on the same push-button? K. Wittingham responded: “Why not use a D-Flip Flop with the switch connected to clock, and ...

With an unlikely GFCI in the fan’s circuit main, this use of the ground wire could cause false tripping. Figure 2 This is the PCB layout for the circuit. Figure 3 Here is the completed board for this ...

[Victor] sends in this quick project on turning an Emergency Stop Push button into a ‘Build’ button. From the looks of it, this project uses a Teensy 2.0, which sports an ATMEGA32U4.
