Fading an LED

Fading an LED

Fading An LED: Connection

• Connect LED to pin 11 and GND
• Pins 3,5,6,9,10,11 are PWM pins
• Can simulate Voltages between 0V and 5V.

Fading An LED: Analog Blink

• Comment out //digitalWrite code and insert analogWrite instead.
• HIGH and LOW are replaced with a range from 0 to 255. (LOW = OFF = 0 | HIGH = ON = 255)
• Analog OUTPUTS are 2^8 bit information, aka 256 values, 0-255 inclusive.

Fading An LED: For Loops

• Use a for loop to repeat a command or process through an iteration.
• for loops require the use of { }
• Here we will have our LED Fade ON.

Fading An LED: Fading On and Off

• Copy the for Loop you use to Fade On the LED and change the parameters to go in the opposite direction.
