Introduction: How to Make a Continuity Tester Extremely Easy
This a very easy to make a continuity tester , instant make continuity tester
Step 1: Have a Look on Video First
Step 2: Material Required
To make this continuity tester we don't need any high end items
lets see what we want
- A pencil
- A LED
- A remote with batteries
- Some piece of wires
Step 3: How to Make
After getting all the items.
Solder one with the one end of LED and keep other end of LED free we will use that end as a testing terminal.
stick the LED at tip of pencil so it became easy to handle and testing
now connect the wire from LED to the positive terminal of battery.
connect one wire with negative terminal of battery and its other end kept open
now that open end are our testing points
if you short then circuit will close and LED Glow.
in this way we can check continuity when ever we need
this tester is easy to make almost without any cost
please watch video for better understand
thanks for your attention

You need to add a resistor to limit the intensity in the Led or it
will burn. Another interest of having a current limiter is that you
won't destroy so many components when trying to test their "continuity".
Last, batteries will last longer.

would you put the resistor on the battery side or probe side

I wouldn't use it on anything but wires.
