Astable Multivibrator (Oscillator) Using a 555 Timer IC

SOLVED: (a) Design an astable multivibrator using a 555 timer IC with a duty cycle of 72.1%. tON = 1.86 seconds and RB = 47 kilohms. (b) Write your solution on an A4 paper and draw the circuit diagram with proper pin and component labels. (c) Connect the circuit in TinkerCAD and simulate it. (d) Connect a 330-ohm resistor in series with an LED between the output terminal of the 555 timer and the ground. Observe how many seconds the LED is ON and how many seconds it is OFF. (e) Attach
