Im new to arduino and were creating a simple timer using arduino wemos d1h- esp 8266 based. I based the code and the arrangent of the wires from a youtube video but when I plug it, the led did not open. So we tried to isolate the led to test it but it still doesn't work. What could we do yo fix this
Welcome to the forum
We will need a lot more detail
Please post your sketch here, using code tags when you do, and a schematic showing the components of your project and how they are connected. A photo of a hand drawn circuit is good enough
In my experience the easiest way to tidy up the code and add the code tags is as follows
Start by tidying up your code by using Tools/Auto Format in the IDE to make it easier to read. Then use Edit/Copy for Forum and paste what was copied in a new reply. Code tags will have been added to the code to make it easy to read in the forum thus making it easier to provide help.
