This is a listing for an electronic combination lock kit that we developed using the LS7222 combination lock IC as a platform. When you purchase this kit, we will send you a PCB, and all the parts required. Instructions for assembly are all given in the video above. There is also a demonstration in the video on how to use the kit with your MCU. We also briefly talk about the data sheet circuit, and talk about how you can go about manipulating the functionality of the circuit by changing some passive components on the board. The instructions are ALL in the video, so if you're interested, have a look. WE ALSO SELL THESE ASSEMBLED! Just look through our store! If you have any questions, send us a message!
This kit includes:
1) A Custom PCB (Printed circuit board).
2) All of the components required to build the kit.
3) Round the clock access to the instructional video =) We will send a piece of paper with a reminder of how to view the instructional video on our website.. Or... You can just come back to this listing and see it again here!
