Extended Arduino Libraries
The following are some of the extended Arduino libraries which are useful to code and easy to understand.
1)pinMode(pin, mode): Used in void setup() to configure a specific pin to behave either as input or output.
2)digitalRead(pin): Reads a value from a specific digital pin and results either high or low.
3)digitalWrite(pin, value): It is opposite of digitalRead(). In this the value is written on digital pin.
4)analogRead(pin): Reads the value from the particular analog pin with a 10-bit resolution.
5)analogWrite(pin, value): The provided value is written on the analog pin.
6)delay(ms): It pauses your program for the amount of time as mentioned in millisecond.
7)Serial.begin(rate): this function starts the serial port and sets the baud rate for data transmission serially.
8) Serial.Printin(data): Prints the data on the serial Monitor.
