b'ARDUINO PRO TIPARDUINO SERIAL MONITOR: The Blink | Arduino 1.8.9Serial Monitor is one of the Arduino IDEsSerial Monitormany great included features. WhenBlinkworking with embedded systems, it helps to see and understand the values that your program is trying to work with, and it can be a powerful debugging tool when you run into issues where your code is not behaving the way you expected it to. This Arduino/Genuino Uno on/dev/cu.usbserialDNO18JWScircuit introduces you to the Serial Monitor by showing you how to print the valuesSerial Monitor button in the upper-right of from your potentiometer to it. To see thesethe Arduino IDE.values, click the Serial Monitor button, found in the upper-right corner of the IDE in most recent versions. You can also selectTools > Serial Monitor from the menu.You should see numeric values print out in the monitor. Turning the potentiometer changes the value as well as the delay between each print.If you are having trouble seeing the values, ensure that you have selected 9600 Serial Monitor printoutbaud and have auto scroll and baud-rate menu. checked.CODE TO NOTEA variable is a placeholder for values that may change in your code. You must introduce, or declare, INTEGER VARIABLES: variables before you use them. Here were declaring a int potPosition; variable called potPosition of type int (integer). We will cover more types of variables in later circuits. Dont forget that variable names are case-sensitive!23 : circuit 1b'
