Here we study a simple IC 555 based monostable circuit whose output monostable time duration starts only after the input trigger is released thus making sure that the trigger ON time duration is added with the monostable’s pre-programmed ON time duration. The idea was requested by Mr. John Brogan Technical Specifications I would like to […]

How to Trigger a Camera Remotely without Physical Presence
In this article I have explained a simple RF remote control circuit which can be used for activating a digital camera remotely, by a press of a button. The idea was requested by Mr. Pat Circuit Objectives and Requirements I’m Pat, from France. Congratulations for your blog & website about electronic’s devices : it’s the […]
Introduction to Schmitt Trigger
Almost any digital circuit used in modern high-speed data communications needs some form of Schmitt trigger action on its inputs. Why Schmitt Trigger is Used The main purpose of a Schmitt trigger here is to eliminate noise and interference on data lines and provide a nice clean digital output with fast edge transitions. The rise […]
