INTRODUCTION

WHAT IS MICRO:BIT?

Micro:bit is a pocket sized microcontroller
designed for kids and beginners learning how

to program.
Micro:bit comes with a variety of on-board
modules including 25 LED light that also
support light detection , 2 programmable

buttons, motion detector, compass and
bluetooth.

5. TURN ON LED
Aims:

To use a button to turn an external LED 'on'
To use a resistor to create resistance in the flow of electric
current

This experiment will use a variable to track whether an LED
should be turned on or off when a button on BBC micro:bit is
pressed. Using a digital wire, we can change the status of the

LED from off (0) to on (1).

6. USING THE BBC MICRO:BIT TO CONTROL A SERVO

Aims:
To control a servo using the micro:bit

This experiment will using a battery pack to provide power
directly to the servo and only using the BBC micro:bit to
supply the control signal to the servo is the best way to

protect your BBC micro:bit from harm and to ensure that you
are getting the full amount of torque from the servo

Coding:

Steps:
1.The servo has a three wire connector. The brown wire is
ground, the red wire is positive and the orange wire is the
signal wire. The BBC micro:bit will send instructions to the
servo from the P0 pin via the servo's signal wire.
2. Use the jumper wires to connect the circuit using the
connector block
3. Use the crocodile clips to connect jumper wires and BBC
micro:bit.

7. SIMPLE EXPERIMENT USING SERVO AND PIEZO BUZZER

Aims:
To learn how to control both servo and piezo buzzer using
micro:bit

This experiment included the BBC micro:bit comes with piezo
buzzer and servo in this kit serve that a good deal in adding
audio and motor movement to your application. Using a
battery pack to provide power directly to the servo and
buzzer.
