Homemade solinode door lock.
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.
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.
Connections between arduino and rfid are given in the table below.
I built this for my garage door for less than 30 0.
And they re real solenoids not rack and pinion motors like the stuff used later.
A 10k resistor is used between the vcc and out pin of the hall effect sensor.
These guys are strong.
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.
Build a remote control deadbolt.
