I would require all LEDs to be at 30% brightness, and LEDs to be 100% brightness when vehicle movement is being detected by IR sensors at LED1 and LED7.
You would have to come up with the circuit diagram, and coding according to what I've stated above.
Also, an explanation for the coding.
Hello,
I am Malik Umair Latif, experienced in Embedded System Designing and PCB Layout and Manufacturing.
I can give you the code in 1 hour counting from the moment you give me this job.
Rest we discussed in messages.
Regards,
Umair.
