UltraSonic Sensor #5

Open osalas0013 opened 4 years ago

osalas0013 commented 4 years ago

//Function will read analog pin connect to ultrasonic sensor //That value will be assigned to a global variable. Call it 'brightness' void ReadSensor()

//Function will use analogWrite to assign the value 'brightness' to your PWM in void LEDBrightness()
