Intruder alarm using ubits

[LiyouZhou]

Problem: I have a door mounted ubit, with a magnet mounted to the frame.

1. 2 microbits not physically connected to each other
2. One detecting magnetic field, if the field strength is > 100000. Send a radio signal.
3. The second ubit constantly listens to radio signals, if a signal is received, light up all leds.

Steps:

1. try sending a radio signal and see if it is received
2. Try reading the magnetometer in a loop and print out the strength. Experiment with magnet and what the reading you get.
