Ex02 - Interactive LEDs
1
1
Connect three LEDs with P0, P1, P2 pins and GND.
1. GND is the ground Pin (Negative)
2. P0/P1/P2 is the Pin of the Microbit we
can programmable to control
releasing electricity or not.
Use your fingers to control LED
2
LED have two feets, the longer one is positive and shorter one is negative.
