When a 555 timer is operating in Astable mode we obtain a pulse on the output pin whose ON time (Time high) and OFF time (Time low) can be controlled. This controlling can be done by selecting the appropriate values for the Resistor R1,R2 and capacitor C1. Electronics ponents: The 555 in Astable (Oscillator ... Another common way to use a 555 timer is in astable mode. The term astable simply means that the 555 has no stable state: Just as it gets settled into one state (say, the output at pin 3 high), it switches to the opposite state (output low). Then it switches back to the first state, and so on, ad ... 555 Timer as Pulse Width Modulation (PWM) Generator ... The 555 timer chip has been a staple of electronics tinkerers for decades as it can be configured into a wide range of different modes with just a handful of external components.
