We are starting from the basics- Astable Multivibrator . The internal structure of a 555 Timer IC consists of 2 comparators and a SR latch. Components: 1. 7805 IC 2. 555 Timer 3. Led 4. Resistors-220 ohm, 100k ohm, 1k ohm 5. capacitors- 1 microfarad, 0.01 microfarad, 0.1 microfarad 6. Connecting wires, Breadboard Circuit Diagram: Working: I found the following source to be a great summarizer in addition to the video made by Ben Eater. It delved into the theory more. https://youtu.be/iJYm_BGqa1A?feature=shared Fig 2: Source- 'All about Electronics' Inference: It works based on charging and discharging of the capacitor through the resistors. The voltage is compared and '0' or '1' is sent from the comparator. When S=1, R=0-> Q=1 When S=0, R=1->Q=0 When S=0,R=0->Q=previous state The charging and discharging results in a square wave output Fig 3: Source- 'All about Electronics' The timing/frequency/duty cycle is fixed in order to know the value o...
