NowyoushouldseeLEDsE0-E7flashing
in pairs, with a period of 400 ms. Touch
with your finger one of the on-board
thermistors (RT1, RT2, RT3, RT4) placed
on each corner of the board. By touching
the thermistor, you will increase its

temperature is detected by the DSC and
itwillchangetheLEDflashingpattern.If
you touch RT1, LEDs E0 and E1 will start
flashing with a period of 200 ms. All other
LEDs will be turned off. The thermistors
and the LEDs are related as follows:
Ifyouremoveyourfingerfromthe
thermistor, the LED flashing will return to
the default pattern.
