Step 2: Circuit Diagram

Step 3: Working Explanation

Hi in this circuit 555 timer ic is use to generate a specific pulse at output pin number 3

this pulse will gice high and low signal due to which the bi color led glow once red and once green

a transistor is used to amplify the output current to drive led

You can set any delay for ON OFF using different value of capacitors

Thanks
