daw9000 2:2f72859d7247 26 Using the BBC MicroBit.
daw9000 2:2f72859d7247 27 This program shows the Temperature which can be adjusted up or down to reflect true ambient temperature using B (down) and A (up).
daw9000 2:2f72859d7247 28 Pressing A+B together changes mode from temperature to compass text heading display to compass heading graphic. Pressing A+B will circle around the three
daw9000 2:2f72859d7247 29 modes.
daw9000 2:2f72859d7247 30 Touching pins GND and P0 dims display, GND and P1 brightens display. GND and P2 shows actual device temperature.
