How do you reprogram a door keypad?
Programming a Keypad PIN
- Be sure to clear the garage door area of any obstructions.
- Locate the LEARN button on the door control.
- Press the LEARN button twice. The LED will flash.
- Enter a 4-digit PIN of your choice on the keypad, and press ENTER.
- The opener lights will blink, indicating the PIN programming is complete.
How to make a door lock with Arduino?
In the previous post, you learned about RFID and keypad based door lock system in which you had to first scan the right tag and then enter the correct password to open the door lock. Now we are going to add the Sim900 module in that system to make it an RFID and Keypad based Door lock and alert system using Arduino.
How does RFID door lock and alert system work?
Upon scanning the right tag and entering right pass, it will open door and send confirmation message otherwise it will send alert message. In the previous post, you learned about RFID and keypad based door lock system in which you had to first scan the right tag and then enter the correct password to open the door lock.
How does the Arduino connect to the keypad?
The I2C LCD communicates with the Arduino through the I2C protocol. Different Arduino boards have different I2C pins. The I2C pins on Arduino Uno and Arduino Nano are A4, A5. Next connect the keypad with Arduino. The 4X4 keypad has 8 connections but we don’t require the last column of keypad.
How does the RFID reader work on an Arduino?
The RFID reader communicates with the Arduino through the SPI protocol and different Arduino boards have different SPI pins. To test if the RFID reader is working properly or not, upload the “dumpinfo” from the examples in the Arduino and see if it is showing the information of the tags on the serial monitor or not.
