555 Timer/Oscillator

Basics of 555 Timer/Oscillator This is 8 pin IC for accurate time delays and oscillations in circuit. By controlling the capacitor time constant, the time delay and square wave generation time period is controlled. The time delay is controlled by single resistor and capacitor circuit and the square wave form is controlled by two resistors […]
