WebYou can use the Arduino environment’s built-in serial monitor to communicate with an Arduino board. Click the serial monitor button in the toolbar and select the same baud rate used in the call to begin (). Serial communication on pins TX/RX uses TTL logic levels (5V or 3.3V depending on the board). WebReads the value from a specified digital pin, either HIGHor LOW. Syntax digitalRead(pin) Parameters pin: the Arduino pin number you want to read Returns HIGHor LOW Example Code Sets pin 13 to the same value as pin 7, declared as an input. int ledPin = 13; // LED connected to digital pin 13 int inPin = 7; // pushbutton connected to digital pin 7 son of magic rick riordan
