    What type of Arduino? On some pin 1 is one of the hardware serial pins. You can’t use that pin for other things like LCDs if you are using serial. Commented Jun 26, 2020 at 1:07
  • @Delta_G The board is Arduino Uno and you are right. Changing the pin from 1 to 3 solved the issue. Tnx! I wonder how many of 846,000 viewers of this youtube had the same issue? youtube.com/watch?v=dZZynJLmTn8&pbjreload=101 :-) Commented Jun 26, 2020 at 1:16

  • @jsotola the question was downvoted so I thought perhaps I misrepresented the issue. I restored the previous title to your suggestion. tnx. Commented Jun 26, 2020 at 2:02
  • somebody probably downvoted the post because you did not check which pins are used by the serial port Commented Jun 26, 2020 at 2:11
