    0 EZ0 sensor

    Above is a simple distance sensor I bought.
    I want to turn on LED's for a distance to a wall warning device.

    RED = stop!
    Amber = Warning prepare to stop
    Green = ok to drive

    I will simulate using a Dragon 12+ plus microcontroller board and debug 12.

    I need code for this in Assembler language.

    Once I have it I want to consider sounds such that:
    RED led = constant warning chime
    Yellow = slow beep
    Green = no beep
    Flashing red LED = you are closer than 1.0 feet to a wall and are about to hit.

    I will use the AN analog o/p of the maxbotix sensor.
    The device turns out a voltage corresponding to the distance.

    So, when you are at 5 feet or greater from a wall we should turn on a green LED.

    If we are at 2.5 to 4.9 feet we should turn on a Yellow led.

    If we are at 2.4 feet to 1.5 feet = red.

    I have the idea that anything under 1.4 to 0 feet should flash a red led!!!

    Does anyone have and idea how to do this or how to at least program the microcontroller so that it can illuminated the corresponding LED's?
