Arduino

Hardware

ESP8266

The ESP8266 is used to connect the lock to the internet. I'm using an NodeMCU devboard because of the various GPIO, the integrated powersupply and because a shield to drive the solenoid is availiable.

Other Hardware

• NodeMCU Motor Shield
  • Used to drive the solenoid as it requires far more current than a microcontroller could provide
• Solenoid
  • Small "ZYE1-0530" type solenoid i got from Amazon, for application in a real house there are some availiable that can be directly mounted to the door.
