{"title":"Reed Switch Module","handle":"reed-switch-module-1","url":"/products/reed-switch-module-1","description":"\nA reed switch is an electrical switch which is operated when a magnetic field is brought near to it. \nCheck out our tutorial here\nDigital 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\nVoltage 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. \n","vendor":"Little Bird","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4252,"title":"Default Title","sku":"LB-24-REED","price":4.24,"compare_at_price":8.6,"on_sale":true,"in_stock":true,"available_quantity":43,"option1":"Default Title"}]}
