b'CODING CHALLENGESADD MORE COLORS: You can create many more colors with the RGB LED. Use the analogWrite() function to blend different values of red, green and blue together to make even more colors. You can divide the potentiometer value and make more nested if statements so that you can have more colors as you twist the knob. MULTI-COLOR BLINK: Try using delays and multiple color functions to have your RGB LED change between multiple colors when it is dark.CHANGE THE THRESHOLD: Try setting your threshold variable by reading the value of a potentiometer. By turning the potentiometer, you can then change the threshold level and adjust your night-light for different rooms.FADING THE LED: UseanalogWrite() to get your LED to pulse gently orsmoothly transition between colors.TROUBLESHOOTINGOpen the Serial Monitor and make sure that your photoresistor is returning values between 0 and 1023. Cover the photoresistor; the The LED nevervalues should change. If they do not change, check your circuit. turns on or off Make sure that your threshold variable sits in between the value that the photoresistor reads when it is bright and the value when it is dark (e.g., bright = 850, dark = 600, threshold = 700).My LED doesntMake sure that all three of the pins driving your RGB LED are set to show the colorsOUTPUT, using the pinMode() command in the setup section of the that I expect code. Then make sure that each leg of the LED is wired properly.Nothing is Try unplugging your USB cable and plugging it back in.
