Introduction

Connect two LEDs to a Bit Board and control them with a micro:bit

We'll make the LEDs blink on and off independently from each other.

  1. We'll use Maker Tape to connect the LEDs to the Bit Board on a LEGO baseplate. Connect the Negative (-) sides of the LEDs to a Ground (GND) hole on the Bit Board. Connect the Positive (+) side of the first LED to Pin 1 on the Bit Board.
    • We'll use Maker Tape to connect the LEDs to the Bit Board on a LEGO baseplate.

    • Connect the Negative (-) sides of the LEDs to a Ground (GND) hole on the Bit Board.

    • Connect the Positive (+) side of the first LED to Pin 1 on the Bit Board.

    • Connect the Positive (+) side of the second 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 Blink Separately program: https://makecode.microbit.org/_WTR1APfi3...

    • This code will make the LEDs blink on and off independently from each other, and at different rates.

    • We're using two different forever blocks in this code. One of the advantages of the micro:bit over other controllers is that it is very easy to have concurrent "forever" loops running at the same time.

    • 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 LEDs will be blinking at different rates, but you can easily change that by making changes to the code and reloading your new version onto the micro:bit
