I am follwing https://bittle.petoi.com/4-configuration and I want to run the tests, like the Buzzer test.
My question is what happens after I have tested?
I am new to Arduino and the NyBoard so I don't know what happens with a sketch.
Does it run forever until I turn the battery off?
Does it stay forever on the board or is it in RAM and then disappears?
Does it take up memory?
Does it erase the prestored routines?
Can I send a command like "beep()" on the Serial Monitor? or is it only what is written in the "void setup()" function?
How many sketches can I upload?
How do I choose a sketch?
Side note: We only maintain the OpenCat codes on GitHub. We always make sure the WriteInstinct.ino and OpenCat.ino are from the same release. The codecraft interface is developed by another company. It's a wrapper based on OpenCat.ino. It may be outdated in the future.
