Okay.... after it taking longer than it should have, I figured out how to make the series of LEDs work!
Even at ten inch increments!!!

I figured out that I needed to write, threshold * 2 for the second LED. Then I did times 3 for the next, and then times 4!

I honestly can't believe I figured it out. I'm so dang proud of myself. Lol 😎
Thanks for the challenge!
So pumped!!!

thank u helped me before getting killed in the program class dude for forgetting to save the process

[veryvaughsome]

Great tutorial! does everything it says and does it well. now i gotta figure out how to make it turn on leds depending on distance

[Studs_Studio]

this is amazing! i made it so if youre too close a buzzer starts beeping. i want to use this on an rc car to automaticly stop

[motomichinakamura]

Is there any enclosure or casing available for this setting?

My little brother burst into laughter when he heard "Male to Female pins" lol

I want to make a disc shooter that can be attached to the arm, and I want to add a control system to it, basically when the palm "blocks" the shot, the disc shooter will not fire.
So I thought to connect this sensor to perform this operation, do you think it is correct? Does it suit my needs?

Rite Buddies Dude, Worked first time awesome! TFS, GB :)

Thanks for the detailed and easy to understand video helped me a lot !!

[Zemabri]

im using this against my dog, not for a distance sensor

[limuelmagbanua]

I'm having trouble tryna use a grove model of ultrasonic sensors, and it keeps calculating to 0

[MotomichiStudio]

How far can the sensor work in terms of distance?

[imahumanbeng]

does this work with arduino maker uno x???

[jomfawad]

does it work outdoor if theres sunlight?

[cal]

I am definitely failing this class omg

[kastriotgega]

Does it work for underground dedection?

[adityamandal]

In your Automatic Braking project using Ultrasonic sensor, I have changed the PING))) sensor to HCSR04. But there's a line in the code saying
distance = readUltrasonic(pingPin)
Now how to change that👆

[joshwatp]

When writing the exact same code it comes up with trigpin was not declared in this scope pinmode

[bfuh_]

Does this sensor also detect the intensity of the reflected wave?

[joshwatp]

Also saying pinmode was not declared in this scope
