Bi-Stable Mode(Flip-Flop): In bistable mode, both the output states are stable. At each interrupt, the output changes from low (0) to high (1) and vice versa, and stays there. For…
MONOSTABLE MULTIVIBRATOR IN 555 TIMER AND ITS APPLICATIONS
Mono stable mode: In this mode one state (either high or low state) is made as stable state, when interrupt is applied the circuit goes to unstable second state and…
555 TIMER AND ASTABLE MULTIVIBRATOR APPLICATIONS
Overview : The 555 Timer module is used to generate pulses for various purposes. It is a highly stable integrated circuit that can produce accurate time delays and oscillating pulses…
