Digital Electronics TM. 1.2 Introduction to Analog.", "Image ImageDescription": "The 555 timer is an 8-pin IC that is capable of producing accurate time delays and/or oscillators. In the time delay mode, the delay is controlled by one external resistor and capacitor. In the oscillator mode, the frequency of oscillation and duty cycle are both controlled with two external resistors and one capacitor. Presents a brief overview of the 555 timer.
