The number of the LED is held in an 'int' variable rather than being a text string. Serial. print can take either a text string enclosed in double-quotes, or an 'int' or …

Introduction to Arduino

Arduino is able to detect whether there is a voltage applied to one of its pins and report it through the digitalRead() function. There is a difference between an on/off sensor (which detects the presence of an object) and an analog sensor, whose value continuously changes.

essages from your computer to an Arduino board (over USB) and also to receive messages from the Arduino. The message “Enter LED Number 0 to 9 or 'x' to clear” has been sent by the Arduino, and it is telling us what you want to turn on (where 0 is the bottom LED, 1 is the next one up right up to 7 for the top LED). Try typing the
