Programmable robot with micro:bit

(7) Press button-B of the micro:bit. then observe the micro:bit LED operation again.
micro:bit reads the sensor’s value from analog input ADC1 and shows on its
LED display.
(8) Stick the black tape on the floor. Place the robot by the sensor position must
over the black tape.
(9) Press button-A of micro:bit then observe the micro:bit LED operation.
micro:bit reads the sensor’s value from analog input ADC0 and shows on its
LED display. The value must low because the sensor detects the black surface. It is
during 0 to 4095. Normally the black surface will be detect data lower 1000
(10) Press button-B of micro:bit. then observe the micro:bit LED operation again.
micro:bit reads the sensor’s value from analog input ADC1 and shows on its
LED display.
User can use these same steps for the Line tracing robot example in the next
chapter.
