I finally made an LED blink using an arduino. I had to download the arduino software again with a borrowed computer because my PC died. The code for blinking an LED was already provided so I just copied and pasted it onto the arduino processing software.
I tried to make an LED blink once before, but it did not work. I was having trouble again today, but I went online to see if there were any troubleshooting tips. First, an online forum told me to check to see if the correct arduino was chosen. After I checked, the LED still wouldn’t blink. The online forum then told me to check the port. When I switched around the ports, the LED started to blink!!!
