If you have two paper clips on you the process will be that much easier.
Open and closed a servo door lock.
Servo at 0 position door is closed.
When you insert the bent paperclip stick the straightened paperclip beneath it and move it around.
Void loop char key keypad getkey.
Arduino uno mega x1 breadboard x1 4 4 keypad x1 servo motor x1 red led x1 green led x1 220 ohm x2 jumper cable code listing is here on arduino door lock.
Rfid and keypad door lock and alert system using arduino.
Bend one of the paperclips and fold out the other one as straight as possible.
If the state is high the door is open.
If the state is low the door is closed.
When i saw this i instantly wanted my own for my door.
The servo is connected to pin 11.
In this project we will do an automatic door lock system using a 4 4 keypad and servo motor controlled by arduino.
Recently i rewatched the amazing spiderman in one scene peter parker locks and unlocks his door from his desk using a remote.
Heres how i made it.
This operation can be used to actuate a door lock or a latch to enable you to remotely lock and unlock a door or gate.
After some wiggling your lock will hopefully open.
The command to close the lock after or is pushed.
It will open door and send confirmation message otherwise it will send alert message.
If the state changes from high to low the door closing event is detected.
If key key if the lock is open it can be locked again by pushing o r on the keypad.
After a bit of tinkering i got a working model.
The required circuit is a simple pulse generator based on a 555 timer arduino or pic microcontroller.
