RFID Locking Mechanism
Hi and welcome back to my blog,
Today I worked with a RFID shield from Aus Electronics Direct (https://www.auselectronicsdirect.com.au/rfid-read-and-write-module-kit-for-arduino-project). I used the instructions from Viral Science Creator (https://www.viralsciencecreativity.com/tutorials/arduino-rfid-solenoid-lock). The RFID module is simple and consist of a read and a write function. It uses a radio frequency finder and can detect the individual card numbers which can then allow you to alter code to create an output for when the card is read. For this project I used the read function to create the output of unlocking a solenoid. I used a small 5V solenoid from Core Electronics (https://core-electronics.com.au/solenoid-5v-small.html) and 3x 18650 cell batteries from Hobby King (https://hobbyking.com/en_us/18650-type-2500mah-3-7v-8c.html)(they were the cheapest and safest and available in Australia). By following the instructions I was easily able to produce the locking system I will use in my project (see video and image below). They are a decent amount of wires going from the shield to the Arudino and then to the batteries and relay which is connected to the solenoid. I can combat that by designing and manufacturing a PCB (Printed Circuit Board) or trim down the wire length to make it more compact.
That's all for today, thanks for reading.
Cheers, Perry.
