A continuity tester it's a fundamental tool to have but if you are in a jam without one you can make one out of a simple door and window alarm in this project i show you how.
Step 1: Watch the video
Watch the video and see how it works.
Step 2: Gather the material
You will need for this project:
- Door & Window Alarm
- Two Pieces of Wire
Step 3: Get started
This is a simple project just open apart the alarm and solder two wires between the battery and the reed switch and you're done, you can make the wires as long as you need.
When you close the circuit between the two wires the piezoelectric will buzzer teling that you have continuity.
Step 4: Final thoughts
This is a simple tool to make and although it's not the ideal tool it works great, and if you are testing a connection that it's trigger by a switch for exemple but they are far apart the loud speaker it's really easy to ear.
