555 Timers – How Bistable Mode Works – The Learning Circuit

Karen has been digging into 555 timers for a bit now. In a previous video, she did an overview of the 3 different modes in which a 555 timer can be used. In this video, Karen goes into further detail about one of those modes: Bistable. In bistable mode, signals at two inputs are used to manually set the output of the 555 timer high or low. For example, one button could trigger the output to turn a light on, while a second button could reset the output to turn the light off. This video goes over what is happening in the 555 timer internally to make this type of circuit work. Karen also presents a practical example on a breadboard to show using a 555 timer in bistable mode: https://bit.ly/2wF2xtP
