I can't send program to the Arduino

I could check that Arduino IDE detects ALLBOT. But when I try to send programs to the Arduino Uno, an error occurs. What should I do? I make sure that the switch on the Arduino board is set to Program. I’m a Japanese school student and one of the Science club. Please help me!

Hello @samonndonn ,

I think you are not connected to the correct com port (PC with Arduino).

  • Connect the Arduino uno to the computer with a USB cable.
  • Set slide switch to Program position and open device manager.
  • Check by COM & LPT which COM port your Arduino has.
  • Then set this com port in the Arduino IDE software (tools => port).
