Hi there everyone.
Thank you for taking the time to click on my post. I am new to programming and I am a bit struggling with some things I am trying to make my Arduino do. I have both a Uno R3 and Mega 2560 R3.
So I am working on this Metal Sculpture. It would be my sixth creation and I would like to make it tech infused... So it's basically a metal bust that would detect upcoming people. I want it to open it's eyes mechanically and electronically as a person approach and closes as they leave... not on a timer, but by it's distance... i also want an alarm to sound 1m away from it... I want it's eyes to be dim up green as it opens and dims down as it moves away and eyes shuts. I also want red for when it's within 1.5m.
So right now I have figured out the tf-mini and lights per distance. not the dimming part though. I have added a sweep code but now they seem to run at the same time and won't detect disance but servo is random and lights are random.
I will add my code and yeah... it's a mess.
I am willing to take any advice.

Example code for Benewake TFMini time-of-flight distance sensor.
by Peter Jansen (December 11/2017)
This example code is in the public domain.
This example communicates to the TFMini using a SoftwareSerial port at 115200,
while communicating the distance results through the default Arduino hardware
Serial debug port.
SoftwareSerial for some boards can be unreliable at high speeds (such as 115200).
The driver includes some limited error detection and automatic retries, that
means it can generally work with SoftwareSerial on (for example) an UNO without
the end-user noticing many communications glitches, as long as a constant refresh
rate is not required.
The (UNO) circuit:
* Uno RX is digital pin 10 (connect to TX of TF Mini)
* Uno TX is digital pin 11 (connect to RX of TF Mini)
