In the Arduino IDE, use Ctrl T or CMD T to format your code then copy the complete sketch.

Use the </> icon from the ‘reply menu’ to attach the copied sketch.

Thank you for properly posting the sketch. :slightly_smiling_face:

Following the forum rules is eventual so we can better help you.

What Arduino do you have ?

We also require you to post a schematic of your circuit and a good image of your wiring.

Links to the hardware is also needed.
