• 555 timer help

  
  Electronic Circuits Projects Diagrams Free — Authority: 167
  I have found a simple 555 timer circuit; however, I need to change the button mechanism to something more suitable. It operates with an on-off push button switch but I am just wondering how pin 3 output could be turned on and off with a momentary switch instead of an on-off. only because i can only find a momentary ...
