Ultrasonic sensor and ledstrip color problem

So I've made a parking sensor with the Ultrasonic sensor and a ledstrip. But the ledstrip doesn't turn yellow or green. I think it has to do with the Thresholds. Can anyone help me to set this up? I also want a longer distance greater than 1 meter. This is my code:

Hello @user95613, Welcome to Espruino, a 'Javascript' microcontroller.

May I ask what board you are using, and would you post here the results of running process.env in the IDE please?

I'm using the Arduino Uno

Wouldn't your post serve you better in the 'Arduino' community as this forum is for those that support Espruino?

Yes, I'm afraid you have the wrong forum.

This forum is purely for JavaScript code on the Espruino microcontrollers - what you've posted is Arduino code for an Arduino
