What is Arduino?
Arduino :- It is an open-source electronics platform ( Basically a programmable electronics board ) which are used to create real life projects. Now, you must wonder what is an open-source? well, open-source means any platform whose source code are easily available, one can easily use it anywhere without anyone's permission. Now, how does an Arduino look like? Umm ! So here you go:- Okay, so after seeing the Arduino we can infer that:- It contains 14(0-13) digital input output pins , out of which 6 pins(marked with curly sign) can be used as PWM pins. It has 6 Analog input(only) pins marked A0 to A5 from which we can receive analog values. The digital pins (from 0-13) works on 8-bit mode means that they can give output or receive input having analog values (for Analog or PWM pins) ranging from 0-255. The 6 Analog pins works on 10-bit mode means they give values ranging between 0-1023.
