Car packing system

I have four hc_sr04 , 8 led , 1 ir sensor, 1 servo motor, and 1buzzer . I also have problem with program. Plz write a program for me. Operation is each sensor have 2 led(red and green) , when object is less than 5cm the red led will trun on and green will off, else green will on and red off. It is for car parcking. And at the entry gate ir sensor detect incoming car and servo will open the gate and buzzer will turn on for 1 sec. I have only 2 days to finish it. Plz help me. :frowning:

I also have problem with program.

What program?

Plz write a program for me.

$100/hour. Four hour minimum. When the first $400 arrives, I'll get started.

Operation is each sensor have 2 led(red and green)

Did you buy them that way? It seems to me that the LEDs are controlled by the Arduino, NOT the sensor.

when object is less than 5cm the red led will trun on and green will off, else green will on and red off. It is for car parcking.

Five centimeters? Have you tried parking a real car that close to another car? I hope you don't live anywhere near me, with this silly parking assistant in use.

I have only 2 days to finish it.

You are screwed, then. Why did you wait until the last minute?

More info, drawings, link to IR sensor, more detailed description, etc.

Take this to the “Gigs and Collaborations” sub. Protip: in english, ‘Plz’ is spelled 'Please".
