In a conventional door lock, there is a key to pull or push the latch, and we have to operate it manually, but in a solenoid lock, the latch can be operated automatically by applying a voltage across ...

This design is based off the Adafruit Crikit and MIDI Solenoid Drumkit that they did, but instead uses a non-blocking delay and can handle more solenoids. The Solenoids are connected to 5V/12V and a ...

Solenoids are very commonly used actuators in many process automation systems. There are many types of solenoid, for instance, there are solenoid valves which can be used to open or close water or gas ...

This simple fingerprint door unlock project using Arduino can be very useful for door security, forensics, crime investigation, personal identification, attendance system and much more. In the future, ...

Adafruit has this week announced a new addition to their range of products with the new availability of a 5V Mini Push-Pull Solenoid which is now available to purchase priced at $4.95. The new ...

This RFID Based Access Control System is built around Arduino UNO board, RFID reader module, solenoid lock and a few other components. RFID is a non-contact, automatic identification technology that ...

A solenoid is a type of electromagnet which does a push or pull motion. I used to think controlling a solenoid would be complicated because it would require an advanced micro controller such as ...
