 Programmable robot with micro:bit
3.1.4 Light Sensor
This is fantastic features of micro:bit. Normally
LED is output devices. This is different story of LED
operation. By reversing the LEDs of the screen to
become an input, the LED screen works as a basic
light sensor, allowing you to detect ambient light.
3.1.5 Temperature Sensor
This sensor allows the micro:bit to detect the
current ambient temperature, in degrees Celsius.
Really micro:bit does not detect the ambient
temperature directly. It detects the CPU operating
temperature. Because the micro:bit is open and
CPU inside the microcontroller meet the ambient
direct. We can assume the CPU temperature as
ambient temperature around the microcontroller
3.1.6 Accelerometer
An accelerometer measures the acceleration
of the micro:bit; this component senses when the
micro:bit is moved. It can also detect other actions,
e.g. shake, tilt, and free-fall.
The main device is NXP/Freescale MMA8653FC ;
3 axis accelerometer sensor. Resolution is 10-bit
