💡 Digital Input and Output with an Arduino

Now we should connect the digital input to the physical output.

After downloading the Arduino software, I adjusted many times for the initial settings. Before connecting with the computer, I set up the breadboard. But in the beginning attempts, the tab always told, "stk500_recv(): programmer is not responding." After checking all the settings, I finally found that the board setting was incorrect, which explained why the error message came out.

I followed the instructions to run the program.

The ideal output!
