Reed Switch Module
We have ✅ 47 available of the LB-24-REED in our Sydney warehouse.
A reed switch is an electrical switch which is operated when a magnetic field is brought near to it.
Digital Output (DO)
GND: In electronics, we define a point in a circuit to be a kind of zero volts or 0V reference point, on which to base all other voltage measurements. This point is called ground or GND.
3.3V : 'VCC' stands for Voltage Common Collector. We'll connect the VCC pin to 3.3V on the micro:bit
Voltage is the difference in potential between two points. As it is difficult to talk about voltage without a reference point, we need another point to compare it to.
The Reed Switch Module appears in the following collections:
