Simulation and Practical Implementation

Design, Simulate, and Build a Police Siren Light using BJT$.$ The LEDs should turn on$/$ off alternately giving a blinking $/$dancing appearance. Use a simple Astable multivibrator using two NPN BJT $(2$N$2222$A$).$

Components will be provided by your instructor for practical during your Lab hours:

Use a single $15$ V from NI Elvis Breadboard

Use $2$ BJT $2$ N$2222$A

Use $5$ LEDs on each side $(4$ RED $+4$ BLUE $=$ Total $8$ LEDs$)$

Capacitors, Resistors, and breadboard wires of your choice.

Task#$2-$ Analyze the below questions with the design or with the formula to support them: $($No Help is extended for this, the below question must be answered in the report$)$

Suggest a method to increase or decrease the flickering rate of the LED. Support this with a formula, Oscilloscope output in Multisim.

Do All LEDs Have the Same Characteristics? Explain in Details

I just need task $2-$ values for task $1(100$uF $,56$K $,510)$
