Types of variables
If else condition
Serial Monitor:
The serial monitor is the 'tether' between the computer and your Arduino - it lets you send and
receive text messages, handy for debugging and also controlling the Arduino from a keyboard!
Baud Rate:
Baud rate refers to the number of signal or symbol changes that occur per second. A symbol is
one of several voltage, frequency, or phase changes.
Variable Declaration:
Variable:
Anything which is liable to change or vary is called variable.
Naming Rules of variables:
1.
2.
