I want to resume an Arduino course and in preparation I decided to test my Arduino. I tried to get the onboard led to light up but it was already on when I connected the arduino to the computer. I then obtained and uploaded the sketch to turn the led off but it doesn’t do anything. I decided to purchase a new board to see if it would work, thus confirming a fault with my existing board but the nice man in the shop suggested I ask the hive mind. How do I test my board to ensure that it is working well? If it is then the problem is elsewhere. If the problem is with my computer, then I will come back to you.
Hello @Geoffrey172055 ,
Did you upload the Blink sketch included in the Arduino IDE?
If you wrote your own code did you include:
May not be the problem but just in case.
EDIT: Check if the IDE says
Done Uploading so we know if the code actually uploaded.
Hello Geoffrey and Jaden,
Can you send through a screen capture of the error message you get when attempting to upload to the board. The diagnostics in the Arduino IDE are invaluable in troubleshooting hardware issues. Thanks
Thanks very much for the reply. I have to go out this evening. Will get back to you asap tomorrow.
OK, I guess I might be the arduino chimp here. I set up and uploaded the blink sketch from examples and it worked so the board is OK. It is currently blinking away now. I guess it will stop when I upload something else. I’ll go back now and do the whole course again and this time, keep going until I finish it. Thanks for your help and it is great to know about this resource.
