Arduino sensor and 2 lights code help

[mikeykun]

Hi, i would like to start a project in arduino but i am having trouble in making one because currently i have no idea how to start a code for the 2 lights to function. I read many topics in these forums but none of them worked for me, so please assist me here i would like to have the sensor to detect a distance and it would turn the red led on/green led on.

Step by step.

You shoukd be able to find examlke code that just reads the sensor and prints to the serial monitor.

On the IDE, libraries often come with examples. Look there first.

Have fun getting that going first. Worry about what to do and how with the numbers that gives you as a later step.

Hi @mikeykun,

welcome to the arduino-forum.

@mikeykun

If you want to receive really good help you have to help your helpers by providing detail-information

• what exact type of microcontroller are you using?
• what kind of sensor are you using for measuring the distance?
• depending on the type of LEDs and the type of microcontroller you are using different resistors are nescessary to avoid destroying your leds and your microcontroller.

Your topic is lacking about every detail possible. What kind of sensor? What kind of lights?

I suggest that you start studying the examples that come with the IDE. I'm sure there are examples how to control a LED; the LED can possibly later be replaced by something else. I'm also quite sure that there are examples how to read a button or an analogue signal. Later you can replace that by the code for a digital or analogue sensor.
