Project: Digital Code Lock

Check out the full tutorial blog for this project on our blog link:

Step 1: Installation

For this project, we will build a simple digital code lock that users can enter and key in. In this tutorial, we will show users how a digital code lock system works in an Arduino Interface.

By the end of this tutorial you will be able to : - Set up a digital code lock with Zio and basic 12 keys keypad - Be able to interface with Arduino IDE to program Zio with keypad - Create a program that asks users to enter a six-digit password to unlock - Be able to create a new six-digit password

Step 2: Assemble the circuit

Assemble the circuit following the diagram schematics.jpg attached to the sketch

Step 3: Load the code

Upload the code contained in this sketch on to your board
