Led control code is not working. LED is not glowing through mobile app.
can you please share screenshot of your codes.
Can you take a snap of your connections and send over here?
Make sure the wires are clear in the image.
Keep a note, longer pin is anode and shorter pin is cathode.
- Have you inserted the pin properly?
- Have you tried other pins and LEDs as well?
Let me know so that I can find you out the best possible way to get you the output.
Mostly the error occuring with LED’s is the one has to note the anode(+) and cathode(-) make sure the longer pin is connected to supply and shorter one is grounded.
Double check the code as well, digitalWrite(“pin number”,“Value”) mention the correct pin number.
Hope this helps!
