guys this really simple code makes my relay Board Buzz whenever i connect the power Supply to it i need Help please with it quick
i connect positive from the supply to JD-VCC and ground to ground and 5V to VCC in the relay Board
what's Wrong ? I need the most simple solution

You seem to have avoided all the useful information such as ...

  • What Arduino board are you using?
  • What relay board are you using - post a link to its datasheet?
  • What power supply are you using?
  • How have you everything connected - make a simple pencil drawing and post a photo of the drawing. See this Simple Image Guide

And anything else that you know about it and we don't.

...R

post a drawing of what is connected where... what do you have on Pin 3 for example ?

4

Using Arduino UNO
Using 8Channel 5V Relay Board Compatible With RaspberryPi And Arduino
Using 5V 30A PowerSupply

5

No devices Connected I'm Simulating All Sensors with normal Wires
Connecting them with each other Simulating them working
I"M NOT CONNECTING REAL SENSORS

6

so nothing is connected to pin 3? it's floating? ... that's your problem in that case

Jumper Wires EveryWhere

going where? see answer #5

A bread Board And then I connect them with each other with a switch to give a signal as there was a Sensor

please be specific...

Arduino Pin 3 <-- wire --> breadboard <---> switch <---> ? ? ? (5V, GND, something else)

any pull down resistor?

--> if you don't have a pull down resistor, when your switch is not active you have a floating input (since you don't use the built in pullup) and can't really trust what you read there.... so you'll get HIGH and LOW and your loop will very quickly turn on and off your relays...

is that how things are wired?

I asked you in Reply #1 to post a drawing showing all your connections.

We are still waiting.

PS ... And a verbal description of wiring is too easy to misunderstand - it must be a diagram.
