The yellow light on the back of the micro:bit is the status LED.
It flashes yellow when the system wants to tell the user that something has happened.
See how the @boardname@ shows numbers, text, and displays images by watching this video about LEDs:

Button R on the back of the micro:bit is a system button. It has different uses.
When you have downloaded and run your code onto your micro:bit, press Button R to restart and run your program from the beginning.

## USB connection
When you plug in your micro:bit via [USB](/device/usb), it should appear as a ``MICROBIT`` drive.
@ -62,6 +71,10 @@ There is an accelerometer on your micro:bit which detects changes in the micro:b
It converts analogue information into digital form that can be used in micro:bit programs.
Output is in milli-g. The device will also detect a small number of standard actions e.g. shake, tilt and free-fall.
Watch this video to learn how the accelerometer works:

## Temperature
Temperatrue is measured on the @boardname@ by detecting how hot its physical CPU material is. Since it operates nearly as cool as the air around it, the temperature it measures for itself is a good approximation for the ambient temperature (the temperature near and around it).
