Thanks

Welcome to the group.

Please try and explain exactly what’s needed.

Before asking questions:

If your sketch was generated with an AI like ChatGPT or by someone else tell us in your post.

  • Questioners know what their hardware and software looks like but the volunteers here do not; you need to fully explain what’s not working, and how it is supposed to work.
  • Please read all the posting guidelines before asking your questions; follow these guidelines in your post.
  • As always, show us a good schematic of your proposed circuit.
  • Show us good images of your ‘actual’ wiring.
  • Give WEB links to major components.
  • In the Arduino IDE, use Ctrl T or CMD T to format your code, then copy the complete sketch.
  • Use the < CODE / > icon from the ‘posting menu’ to attach your copied sketch.

When you follow the posting guidelines, volunteers can be more effective.

And we have to guess what stuff you have?
No thanks.

I have relay module, ultrasonic sensor, 12v white led strip, 12v power supply and the arduino

7

can we have the reference of the components:
because there are a lot of type of relay module, a lot of type of ultrasonic sensor and so on.

thank you very much

for the code, the first thing you should do is an algorhytme.
Do you have one ?

11

No, can u help?

12

Have you worked through any of the simple introductory examples in the IDE?

13

here is the algorhytm I'm thinking about:

1: LED OFF

2: IF THE SENSOR RECEIVES DATA
THEN TURN ON THE RELAY MODULE
ELSE GO BACK TO THE BEGINNING

3: IF THE SENSOR RECEIVES DATA
THEN TURN OFF THE RELAY MODULE
ELSE GO BACK TO THE PREVIOUS STEP

but for the code it will be more difficult because i am also a beginner but I can give it a try later.

14

An ultrasound ranger will typically "RECEIVE DATA" or it will timeout.

(Please don't SHOUT)

Thanks for help!

Have you discovered Wokwi yet??
HC-SR04 Ultrasonic Sensor Example

have fun.. ~q

17

I'm curious - does the simulator mimic late returns from the previous ping, if you ping too frequently?
Is it a configurable option?

18

only param i see on it is initial distance..

No idea, I don't have a paid account, so maybe there's more??

sorry.. ~q

So, I'm guessing no correction for ambient temperature either.

I'm a beginner in prog
