Microbit Introduction

BBC:Microbit

• Micro-processor for control physical devices

• Builtin sensors / actuators

• Bluetooth and radio communication

Sensor

• A type of input device - collect data for processor

• Gather data automatically from environment

• Sensor works continuously, non-stop 

• Sensor data are usually analogue

Actuator

• Actuator is a type of Output Device, which makes processed information into human readable / detectable form (i.e. physical)

• Actuator usually outputs in the following formats:

Some Types of Actuator Outputs

• Light (e.g. LED)

• Heat (e.g. Heater, Cooler)

• Motion (e.g. Motor)

• Sound (e.g. Buzzer)

• Electro-magnetic (e.g. Valve)
