CH1-C - LED Fade Loop

We'll use Maker Tape to connect the LED to the Bit Board on a LEGO baseplate.

Connect the Negative (-) side of the LED to a Ground (GND) hole on the Bit Board.

Connect the Positive (+) side of the LED to Pin 8 on the Bit Board.

You'll notice the Ground on the Bit Board (as well as the LED and other Crazy Circuits components we'll use) is color coded White.

We're going to load the following code for our LED Fade Loop program: https://makecode.microbit.org/_ePaF4fYHr...

This code will make the LED gradually get brighter waiting a 5 milliseconds between each step. We'll use a for loop to do this.

We'll us the analog write command but instead of typing in a number we'll use a variable that changes with each iteration of the loop.

Our loop will save us a lot of typing since we don't have to add 256 analog write commands all with a different number.

We've also added the pause command because the micro:bit can run so fast that without you might not even see the LED slowly fade up from 0 to 256.

Once the code is loaded it should start running immediately.

You can power the micro:bit via the USB cable you used to load the code or you can use a battery pack plugged into the Bit Board.

The LED should start off then get gradually brighter in smooth steps.
