Breakout board and magnetic reed switch wires
  • Sorry for the newbie question, but I am hopeless with electronics. I have a cheap (UK) reed switch, four wires: red, black, yellow and blue. I've put them into the breakout board's IN and GND in various combinations but it refuses to close the switch.

    Simple question then: which wires go where?!

    Yellow: ground
    Red: IN
