Timer 555 bistable – alternative 2

The timer 555-brick can also be connected in a different way, by maintaining its flip-flop functionality. Resetting can be done by using the reset-input instead of the threshold-input. The red LED turns off, when the upper left push button is pressed. Again all signals at the output remain stored, until an alternative input is made. Its not important which type of switch element is used. In addition to the buttons used in this experiment, also MOSFETs and other electronic switching elements can be used in the circuit.
