More information... information... information...

Looking more in depth into Arduino, we have now learnt about resistors, circuits, volt, different type of sensors, breadboard and light dependant resistor (there are different resistors that work for different purposes i.e. one that senses heartbeat and many more). It is also important to know details about the wires because a different colour wire is used for different purposes;

• RED = Voltage i.e. A1
• YELLOW = the Control
• BLACK = connects to Ground

On the other hand, I was confused what INT meant in the electronics context- it stands for integer which means a whole number that can not be dividable. So what is a variable? a string is a variable type but there are different variables as well- analogPIN is an example which is a holder for a number (a place to store information).

I have now become more familiar with Arduino even though at the beginning I was struggling and conscious about it.
