Hi Guys, hope all's well.
I was designing a dark-sensitive LED blinking circuit for myself and need some help. Following is all about my little project.
Scenario
I want to switch on my LED bank automatically in the dark. There are 150 LEDS in my LED bank. The attachment includes my design. However, while simulating on proteus, the circuit doesn't work and an error occurs. Can anyone help me fix this?
Note:-
What I need to know
Thanks

Note:-
- I am not using a ready-made LED lamp or light.
- There is only one LED (D1) showed on the schematic for simplicity instead of the LED bank. I will feed the output from the 555 timer to my LED bank via a transistor.
- The 1 megaohm resistor (R24) will be replaced with an LDR in the actual scenario for automatic switching purpose.
- I am designing this circuit without using a micrcontroller.
What I need to know
- Whether my design is correct or not.
- Why the proteus simulation displays that error.
Thanks
