Hey Everyone....I need a little help on this code I'm a newbie but using AI to help me. I'v noticed that the AI's arent always the smartest. What i am needing this code to do is to use a dht22 temp sensor to measure temp and display (st7789 display) it in a gauge that fills the middle of the screen, with an arrow that is animated moving every 1 sec and creating a long tick mark in the color of green for unchanged, red for rise and blue for drop. Then I am using an ultrasonic sensor to measure distance starting at 12 inchs until touching the sensor. I want it in 1 inch increments and i am using timerfreetone to give me a low tone at 12 and increasing in pitch the lower it goes. I also having it display the distance on the screen. The problem is that i want the tones to be smooth and steady as they go up or down and continue to play as long as there is a reading in my parameters. Can anyone help me and please dont judge me for using AI 
here is the full code:
