Unlocking a Combination Lock Using a Stepper Motor |
Project Description | |
In this project you will use a stepper motor to unlock a standard combination lock. The power of this project is that it uses an old computer such as a 286, 386, or 486 and a few parts that should cost less than $5.00. Instead of building from scratch I have repurposed one of the robots from my previous robotics project. You can read up on that project here. |
How-To the Build Unlocking Device | |
Instructions | An overview and description of how to build the unlocking device. |
Schematics and Drawings | An electronic schematic of the device. This is a repurposing of the robotics schematic. |
Pictures | Pictures, showing the device connected to a lock including a video of it working. |
The Software | This is the software used. The complete annotated source code is provided as well as a executable copy. It's very alpha but it demonstrates the basic concept. |
