Week 8: Arduino Programming

• pinMode(pin #, OUTPUT or INPUT): tells the Arduino which pin is active and whether or not they send out voltage. You need to set pin mode of the pin you are using so that the Arduino knows you're using it for output or input

• analogWrite(pin #, 0-255): tells the Arduino how much voltage to send from a specific pin on a scale of 0-255 (0 sets it to 0V, 255 sets it to 5V)

• digitalWrite(pin #, HIGH or LOW): HIGH sets the pin to 5V, LOW sets the pin to 0V

• Semicolons go after every statement like pinMode(); analogWrite(); and digitalWrite();

• Remember to not touch your mouth when working with electronics, and wash your hands after you work with them to avoid getting lead poisoning
