I'm just a software programmers who are interested in hardware caused by things like arduino. But there is one thing that makes me not ready to do something with arduino, I am afraid to make a mistake in connecting the cables to other cables such as the short-circuit trigger by mistake components installed on arduino thus making a PIN is connected directly to the GROUND that can cause damage to my device.
What I want to ask the arduino team directly via email (https://www.arduino.cc/en/Main/ContactUs) but instead directed to this forum is what should be done to avoid damage, and is there any other way for the prevention of damage instead using the shield/hat such as Ruggeduino shield to make me comfortable even though errors occur unintentionally.
There is no short-circuit prevention feature, besides careful and thorough?
Arduino Team? Anyone? Thank you in advance.
