b'CODE TO NOTEIn circuit 2A, you made songs using a buzzer and the tone() NO TONEfunction, but you gave the function three parameters: a pin FUNCTION: number, a frequency and a duration. You can leave out the third parameter, and the tone will play until you change it or turn it noTone(pin_number); off. noTone() turns off a pin that has been activated with the tone() command.CODING CHALLENGESCHANGE THE SERVO BEHAVIOR: Try changing the way your servo behaves when the distance sensor is triggered.CHANGE THE ALARM SETTINGS: Try altering the code so the alarm goes off from much farther or closer distances.ADD A SECOND MECHANISM: Time to use your imagination! Try your hand at making different objects move with your servo motor. Dont have a cat? Make an interactive pop-up story, room alarm, treat dispenser or automatic fish feeder. TROUBLESHOOTINGThe RGB LED colors arentCheck the connection for the wire and resistor connected to working or a color iseach leg of the LED. Ensure the RGB LED is inserted in the missing correct orientation.Open up the Serial Monitor on your computer. You should The distance sensorsee a stream of distances being printed in the monitor. If doesnt seem to work they are all reading 0 or jumping around, check the wiring on your sensor.Ultrasonic noise pollution will interfere with your distance sensor readings. If you aim two distance sensors at each other, they will confuse each other. The distance sensor still Some air-conditioning systems may also emit noises doesnt workin the ultrasonic range. Try pointing your sensor away from the other distance sensors or moving to a different location.69 : circuit 3c'
