Hi
I have the SRF05 - Low Cost Ultrasonic Range Finder
from robot-electronics.co.uk.
spec is in https://www.robot-electronics.co.uk/htm/srf05tech.htm
one of the pin of this component is high proportional to range (close range is short time of high,100us to 25ms).
Does someone knows how to use a led that will represent the proportional distanse.
The led need to flash faster when the range is short.
Thank you
