Let’s get physical! Programming LEDs and Servos with your micro:bit

What's all this stuff?

Let’s Jump in!

Code for LED (light emitting diode)

When connecting LEDs to your micro:bit:

​

1. Always connect ground (GND) first.
2. Then connect to your chosen pin.

LED Challenge #1

Try changing this number to 700 and see what happens. What about 500? 200?

LED Challenge #2

Experiment with these two blocks: what is the difference between analog and digital?

LED Challenge #3: Make the light blink

LED Challenge #4

Have the LED turn ON when Button A is pushed and turn OFF when Button B is pushed.

Programming a servo to move!

Micro:bit and Servo Setup

You will need:

​

-1 Servo

​

-3 Pigtail alligator clips

What do the colors on the servo wires mean?

Black = Ground

Red = 3 V/Power

White = Pin #/Control Signal

1. Connect the pins to the servo

​

2. Connect the alligator clips to the micro:bit

-Black to ground

-Red to 3V

-White to Pin (does it matter which pin you connect it to?)
