Connections between arduino and rfid are given in the table below.
Homemade solinode door lock.
The door lock solenoids from the seventies gms are the ones to use.
If the solenoid is made of steel or once steel is magnetized it will keep magnetism the solenoid cannot be controlled by the current the advantages of the solenoid will disappear.

They look like a can with a rod coming out of one end usually formed into a loop with a rubber insulating disc in the loop.
The solenoid has wide applications in our daily life it can be applied into solenoid pneumatic control valve solenoid operated the hydraulic valve and etc.
And they re real solenoids not rack and pinion motors like the stuff used later.
The positive pin of the buzzer is connected to digital pin 4 of arduino and the gnd pin is connected to the ground pin of arduino.
A 10k resistor is used between the vcc and out pin of the hall effect sensor.
Hey guys in this video i am going to show how to make a simple solenoid for experiment.
These guys are strong.
