Here are some common delay values for common time delays. One Second delay Example Use delay(1000) to pause for 1 second. 30 seconds delay Example Use delay(30000) to pause for 30 seconds. 1 minute delay Example Use delay(60000) to pause for 1 minute (60 seconds). ...
If the name consists of more than one word, capital letters are used for every new word, because you can't use spaces. Choosing appropriate names for your variables will make a huge difference in the readability of your code. With 'int delayTime;', the variable is correctly declared, but...

delay(100); } You can try to compile the code right now with the Build button, however, you won’t be successful. The reason is probably pretty obvious, you haven’t installed the libraries. To do that you’ll need to use the PlatformIO Library Manager. Using The Library Manager Open ...

delay(1000); } Each one of these errors, though minor, will stop your program from working. It can be quite frustrating at first to tell exactly what is wrong, though it does get much easier with time. A good tip to getting used to Arduino programming is to have another program open ...
